Hi Dr. Bruce Been using most of these these techniques for a few decades with great success.We have grown monsters in 3 gallon pots but they require watering once to twice a day. I feel that it is the oxygen to the roots from drying out so quickly that really excels the performance of the plant along with the other parameters,the same idea on an ebb and flow table. Love the way you put everything in layman's terms. You are a great teacher. Thank you.
No. 100 gallon? That's absurd. Even if you meant 10. And those fabric pots are overrated pieces of shit. I threw them all away because they were worthless and I bought 3 gallon molded plastic pots, because the molded plastic pots last for years and years and you don't need some crap fabric pot to "prune your roots" or whatever duplicitous tricks they are utilizing NOW to sell them. And in a 3-gallon plastic grow container I pulled down one plant that weighed 223 grams which is the largest indoor plant I've grown yet, but...I can usually average 3-4 ounces a plant. Which is respectable. Just a month or so ago I pulled down a plant that weighed 140 grams which is 5 ounces. I dont weigh them all individually but I do occasionally to get an idea. You have to be (and this goes for everyone doing this as a new hobby) In the 25 years I've been growing, I have never seen a bigger glut of shit being marketed with more dubious bullshit claims. Everybody wants your money from the seed sellers to the people at Leafy, and they will tell you (insert random product here ) is the most advanced whatever and it's very popular, and if you just purchase (insert random product here) you will almost effortlessly grow the biggest hardest best shit on the block. And these people are PROFESSIONAL sales people they DONT grow pot they sell equipment to suckers. Here's the secret, because I'm a little pissed and I want people to Never buy weed from a legal shop, because the same people who are the venture capitalists with the money behind the bud tender and all of hippies that are the face of the business are the same people that made money jailing people for pot. Trust me the marijuana you can grow yourself in a tent or closet will be just as good if not better than the profiteers who invaded the industry and want YOUR money. Now, the secret, find someone in the real world who wants make nothing of you pick their brain. Do ALOT of research a semester or even two would be better. But the people with normal cognitive ability and a GOID work ethic are going to be smoking killer pot for a dollar or two a gram. Maybe even 4 but they won't get ripped off on shitty equipment because they were warned, by me, that the in marijuana industry you are chum swimming with sharks.

Good morning Doctor. Thank you for sharing this amazing, beneficial knowledge with us. We highly appreciate it. Please do not ever stop doing the good you are doing. Bless you. And bless anyone reading this comment.
You sir just taught me how to successfully run an indoor facility I thank you for you and your team for the hard work y'all put every second to learn something that helps us all.
Take it with a grain of salt bro, alot of stuff he says is bang on but alot of it doesn't stack up in the real world, you throw 1500ppfd and 60dli at 30c without co2 at your plants and they'll be crippled or just burnt to death not maxing yeild lol. Living soil is a great way to go and coco is an awesome media if using liquid nutes like canna they're great and a few other brands but some have legit scientific studies behind them, blue lab is better equipment, if ya light cycle is cmh or hps etc or 24hr or 18hr or 20/4hr the ppfd to dli changes etc etc and you can see in another vid how banging plants with more than 750ppfd can be harmful for alot of reasons but better yet look at modern growers pushing 900-1100ppfd and having to heavily supplement co2 and cooling ect it's a balancing act and all strain dependent. New vid by first smoke of the day took a tour in mangos facility and 1 room is dedicated to this by strain, different light, different water different nutes different spectrum etc
For years I have watched dr.B and the first time I watched him it was like watching something in German, and through education and learning I have actually understood 90% of this sermon. Even though I wasn't able to convert ppm's from EC at the time of explanation.thanks.
As someone who (didnt) fully understood certain aspects of cannabis growing this does more than a wonderful job at explaining cannabis growth. marvellous job my friend :) Cant wait to start my first indoor cannabis grow in a couple weeks.
Thank you for taking the time to share your work. This is crucial for science based growing. Some people would pay a lot of money for this type of information, and Dr Bugbee is on here teaching a masterclass for free.
Im a biotechnologist engineer and this Dr. knows the fundamentals for plant growth. I mean, its very different when someone explains you with science instead of internet tips with no fundamentals. Excellent!! Viva la ciencia ! Saluos de Chile
Dr Bugbee, interested parties all around the world we thank you for sharing your experience information for free. Apogee's prices are a bit expensive but sharing the info for free, shows that you care. I am already shaving for quantum sensor from Apogee.
Pikos Apikos it’s not free if you see large increases in sales from your content. I find it valuable as well, but don’t suspect it’s entirely altruistic.
That was the best explanation I've seen..I appreciate the knowledge that you shared and I know it will help me extremely well. I cant thank you enough..your the best Bruce..keep up the great work
Heisenberg, is that you? haha! Appreciate you share this well researched piece of information! This really helps us understanding the plant and its behaviour! Great!
.. such a fan! Mad props to Dr. Bugbee and Team. I've learned so much from the artist practitioners on RUclips, but without a scientific base, the horticultural artist is inventing wheels blindfolded. This video pulls so much together in such a useful format. I'm going to go ahead and beg for a version of this dedicated to Soil Grows. Thank you!
Thank you very much Dr. Bruce. I'm learning a lot from you which is necessary for my education because I refuse to go into debt for school. Your work is highly important and appreciated.
Very good lecture, I would like to see one on a totally organic grow. I know the plants don't care where their nutrition comes from but I don't like to feed every day and I am experimenting with a mix of peat, perlite, lime, 2 kinds of compost and chicken manure. I have always used a regular fertilizer but this year wanted to try something different and maybe less work intensive. I hope that it comes out ok it is only an experiment but it still sucks if something doesn't work like you expect. I hope that it works out ok or at least hope that I can correct any issues should they arise. Great video and so much great information.
228 mentally challenged individuals couldn’t understand a single thing,,, keep it up Doctor Bugbee!! it’s amazing having access to this kind of professional approach about such a divine flower. Thank You a lot Doc!!!!!!!
Mate, as you have studied under Bruce, I am wondering the choices of media. He was very unclear about it in the video. IDEALLY 50% Peat 50% Vermiculite This is the bit I was not sure about: Substitutes for Peat were Coir and Hydra-Fibre? Substitute for Vermiculite was Perlite? Is that right?
Man it's been so hard to find more information on cannabis growing online after I reached a certain point... So I decided to take cannabis sciences. But your teaching me on a more advanced level... Man keep it up. Your dope bro. ❤
Hey there Dr. Bugbee. I really enjoyed watching several of your videos. This one in particular. I have been operating a legal cannabis business for 12 years. Most of this time I had growers doing the work that I could trust. I have paid close attention to them and how they work with the plants. I am finding less and less employees that really know what they are doing so I have taken a lead role in my gardens currently. I do a lot of what you say but one thing that stood out to me is: I have been taught to increase nitrogen in veg and decrease it in flower and so the numbers of my NPK's would differ in each stage Do you suggest feeding it the same nutrients all the way from veg through flower?
Hello guys, when pushing the plant to is maximum yields as per the advice in the video, lowering the nitrogen in flowering will lower the EC or Ppm of the feed allowing you to push more of the phosphorus and potassium it requires for producing buds, nitrogen is in high demand in the vegetative stage but can be lowered in flower to push for maximum yields as it's not used so much for budding Hope this helps
I've seen in a few other videos some people (Harley Smith being one of them) saying that you can put your plants to sleep by going all red light for 15 minutes at the end of your daily light cycle. I suppose it would be imitating sunset but I wanted to ask if you had any thoughts on this or if you and your team had looked into maximizing sleep cycles? It would seem like getting your plant into it's sleep cycle and shutting down photosynthesis quickly at the end of day would allow the plant to switch over to consuming the excess nutrients from the day to grow the plant. If all those nutrients are used up, could you wake up the plant with the same flash of red showing sunrise? You went into different light spectrums briefly but I wanted to ask about a bit more detail on your white +red recommend. I want to understand what the extra red is doing and what benefits you've seen from doing so. These are great videos and it's awesome to see cannabis research going on at my alma mater. Please keep them coming I would love to keep up with your progress and learn more about this fascinating subject.
Always love to see the uploads! Thanks for sharing your knowledge and showing us around your spacs. Are you able to share any of your other methods or procedures? I've got a few plants in my Canadian garden that I would like to grow to their maximum potential. Are you using the same EC and NPK ratios throughout the lifecycle; vegetative and generative?
When you don't get to go to college this sort of lecture is just priceless. I wish he did an extended series of these with all the science and material.
Dr. Bugbee is about to announce a 2022 version of his cannabis class. They are still finalizing the details, but you can find more information at www.cannabis.usu.edu and you can also sign up for the mailing list at this link: forms.office.com/Pages/ResponsePage.aspx?id=my81rGProkyc-fTEAEfO_49cb10JTAlJg8TrIOfBdrBURFM5WlpUWEtFME85OFgwMVExRVdCQlEyRi4u
Great video...but ambient (~400ppm) is only going to be useful during veg or flowering with lower light. At 1000-1500 micromols you should be supplementing CO2 at 1000-1500ppm. Temperature, nutrient concentration, light intensity, and CO2 concentration should increase in unison for maximum yields.
Fantastic video, I'm from Canada and I'm trying to fine tune my growing techniques now that it is legal to grow at home. Currently trying my first indoor grow now. Keep making videos and I'll keep watching them! Cheers !
Peat is a bit acidic for most plants - I always use it but always amend it with some ashes to bring the PH into neutral range. Other things most people avoid but probably shouldn't include clay and sand. Clay does a wonderful job of retaining moisture during dry spells for outdoor plantings especially. Sand (washed sand) is also excellent for keeping the soil from clumping and becoming waterlogged and ensures good drainage and aeration of the roots. My favorite amendment is worm castings. These will have baby worm eggs in them so your soil will quickly develop it's own worms and their worm poop is the best nutrient ever invented. So the final amendment is kitchen waste compost - everything from banana peels to old fridge leftovers all go into the compost and the worms love compost mixed in (their favorite food).
@John Jacob Jingle Heimer Schmitt many could say those things are hard to acquire in wild... mushroom growbags are e better option and easily attainable in nature where most humans live. Plastic bags are all you would need not free from a store or sadly the wild its all over
Photosyntech I find that without supplementing CO2 the maximum intensity at the canopy should be 500-700 micromols/second which is a DLI of 21.6-30.2 mol
I've been running 500 watts of lm301 led in a 2x4 tent in a custom made bar fixture for a year now. Room temp is 78 with tent temps at 83, humidity at 60%. No co2 at all, no deficiencies. 10 bars of photoboost strips with 2 meanwell 240 drivers. The plants can get within 6 inches or less without burning and I've got great yields. The trick is to test your runoff. If your ec is rising, then make your solution more dilute until runoff is what you expect. You can run 2000 ppfd like this. That's what they do outside, there's no reason you can't replicate this inside as well. There is no co2 enrichment outside, and inside it is elevated already.
Great insights, thank you doctor. In the past, I did exactly what you have said here to do with amazing results. Gorge Cervantes and Ed Rosenthal were my teachers and the information was solid. Were in the zone now and have come to just mimic nature as best we can and the plants basically grow themselves. Thanks for the awesome video.
Thanks for always dropping knowledge! I was wondering if Dr. Bugbee could do a lesson on clone propagation. To show us environment and proper techniques. To bust myths or confirm 45°angles make a difference or if a node is required at the end etc.
The reason for 45 degree angles is just to increase the surface area for root growth. It isn't necessary but can help. Cutting at or just under a node can help because there are more auxins at these areas of the plant, but the propagation method you use will determine how much this has an impact overall.
I fucking love this man, Im experimenting with my first batch of plants home grown and this kind of content helps so much. I've been watching videos of experienced canna growers doing their thing and its interesting but this takes the cake because its an in-depth explanation of the rundowns the youtubers give on the science . Thank you for your service Mr Bugbee
Thank you Dr. Bugbee for an informative video. Im a 2nd year masters student at Kansas State University doing research on high CBD hemp. This is informative and will help with statistical data on our grow for next year to be able to quantify yield data effectively.
The light used is irrelevant. He states to use whatever the most economic method possible to hit the target DLI. Max umol around 1500 for peak production. I think his entire recipe is based off hitting that 1500umol or 60DLI mark. My question is, does he use the same nutrient solution mix throughout the entire grow? Is there a ramp up?
Was the 20-10-20 for veg? I love how he was talking about lifting the pots and knowing. It helps you move along faster having that skill. Also, Dr. Bruce is most definitely the man!
I wondered the same thing... But i think he Means all the Way Thru wth 20 10 20... I was thinking 10 20 20 idk... All i have though is 15 30 15 for Flowering...
watch Harley Smith videos. He talks about applying a general fertilizer, which this is, and then "spoon feeding" the plant at different stages to give them just what they need at that moment. Also very informative.
have watched every video religously, several times over. this man can show you everything you need to know about growing canabis as well as lots of other stuff. hell he feeds people on mars!!!!
I forwarded this question to Dr Bugbee and he sent this reply: We use the same 20-10-20 solution throughout the life cycle. The optimum input EC is about 1.5 milliSiemens per cm. It is particularly important to keep checking the leachate from the containers to make sure it doesn’t get too high or too low during flowering. The optimum electrical conductivity for the leachate is between 1 and 2 milliSiemens per cm. These are typical units of EC meters; and these are the units of the Hannah, model DiST 4 meter www.hannainst.com/hi98304-dist-4-ec-tester.html?gclid=CjwKCAjw95D0BRBFEiwAcO1KDDtJngMK_6G1yJJ_g8As1bQHl5nAsTT0r-4WNOtRjv9nLX33NxB3ERoC3OwQAvD_BwE The Hannah model DiST 3 reads in microSiemens per cm. The optimum on this meter is thus 1000 to 2000 microSeimens per cm. Either meter is fine, but the DiST 3 over-ranges at 2000, so the DiST model 4 is usually a better choice. The exact fertilizer we use is Peters Professional 20-10-20 - Peat-lite special. The Peat-lite special has higher levels of micronutrients than the general purpose 20-10-20 fertilizer. The higher micronutrient concentration is beneficial-as long as growers keep the overall EC from getting too high. Here is the link to a technical paper I wrote on nutrient management: www.researchgate.net/publication/284231562_Nutrient_management_in_recirculating_hydroponic_culture
@@ApogeeInstrumentsInc In many situations, one powder is not enough because the calcium cannot be part of it. Bruce has the calcium in the media already so he's ok. In my case, I am in Coco and perlite without lime in it. (though it is buffered with Ca and Mg). I was recently using another full line of nutrients with RO water. How ever, I realized that I can leverage the quality of my tap water. It comes in at 50 ppm Ca, so I can reach my calcium requirement by mixing an all purpose blend like 20-10-20 in it. It has carbonates too which are beneficial to buffer the solution and make it resistant to swings in the media. I just need to add acid to bring the pH to where I want it.
@@ApogeeInstrumentsInc I could not find Peters or Jacks 20-10-20 Peat Lite in Europe at all.But after long search i could find "Gobbi 20-10-20" from Italie , what meets the specs from 20-10-20 Peters Peat Lite exactly.Thanks for the knowledge!
@@ApogeeInstrumentsInc Serious question. I decided to try out this method, and when I water the EC is always higher than what I put in. I tried testing each substrate component (I replicated the one in the video, albeit with different brands), and each individual substrate seems to have little affect on the EC. But when they are put together, and I am watering through, the water is coming out with EC of between 2-2.3 mS/cm, even when reducing the input EC to less than 1 mS/cm. I suspect there is a ionic reaction taking place, but I have literally NO clue. The plants seem to be doing ok. Perhaps in the video, you are supposed to take into account the delta EC of the mixture, but it was not mentioned?
Project NEMESI5 Depending on your media, you may need to flush it before planting. As far as build up over time. Water more and more often and your run off will be more consistent. I’ve lowered my ec to .9-1 ec and have been getting great results. Your light intensity, humidity and temperature will also change how the plants uptake nutrients. When it’s dryer, the plants transpire more water, leaving nutrients in the soil. The same thing happens when light intensity is too high. You can have complete control over this by understanding how it’s all connected! Super cool stuff.
Does this also apply for hydroponics? Or what would you advice for hydroponic indoor growing? And is there a way how to increase CBD in spite of THC? Thanks.
In case anybody is making note of the measurements, I would like to point out that at 36:36, the unit of conductivity on the meter was shown in mS/cm instead of mS/m as stated by Dr. Bugbee on the whiteboard.
ideal light: 1500 μmol
ideal temp: 25-30º celsius
ideal humidity: 40-60%
ideal ventilation: active extraction and intraction, and inside ventilation that moves leafs slightly. this will also positively affect co2.
ideal soil: 50% peat, 50% vermiculite, dolomitic lime (1,41g per lt. of soil), gypsum (0,35g per lt)
ideal fertilizer: npk 20-10-20 (0,6g per lt of water), ecc: 1-1,5ms.
ideal watering: slightly overwater (until 10% of water comes out from the bottom of the pot, which should have a tray below). always water with fertilizer. ecc of tray water should remain between 1 and 1,5ms

Take it with a grain of salt bro, alot of stuff he says is bang on but alot of it doesn't stack up in the real world, you throw 1500ppfd and 60dli at 30c without co2 at your plants and they'll be crippled or just burnt to death not maxing yeild lol. Living soil is a great way to go and coco is an awesome media if using liquid nutes like canna they're great and a few other brands but some have legit scientific studies behind them, blue lab is better equipment, if ya light cycle is cmh or hps etc or 24hr or 18hr or 20/4hr the ppfd to dli changes etc etc and you can see in another vid how banging plants with more than 750ppfd can be harmful for alot of reasons but better yet look at modern growers pushing 900-1100ppfd and having to heavily supplement co2 and cooling ect it's a balancing act and all strain dependent. New vid by first smoke of the day took a tour in mangos facility and 1 room is dedicated to this by strain, different light, different water different nutes different spectrum etc
Just discovered your videos as I sprout my first grow, Dr. Bugbee. Thank you for making so much information available, this is a treasure trove!
For years I have watched dr.B and the first time I watched him it was like watching something in German, and through education and learning I have actually understood 90% of this sermon. Even though I wasn't able to convert ppm's from EC at the time of explanation.thanks.
As someone who (didnt) fully understood certain aspects of cannabis growing this does more than a wonderful job at explaining cannabis growth. marvellous job my friend :) Cant wait to start my first indoor cannabis grow in a couple weeks.
Whoa it’s J. Cole!!
How did it go ?
Taking notes the entire time. Thank you Dr. Bugbee for sharing your knowledge with the world.
For the metric, thats 1.41g/L for the lime, and 1.06g/3L for the gypsum
does he mean the entire medium (peat+X) or just for the peat?
I would think the entire medium.
@@MadCatzLover I understand he is speaking about the entire medium too.
i did this, pH of run off coming out to 5.1 and below
@@TheGrowCave And what's the initial pH of the water/water + nutrients?
@@FiesteArg 6.3, strain calls for 6.1. been doing 6.5 since soil was low. Added more lime and they are doing great. WIll start pH'ing to 6.1 next week
I've taken more notes on this video than I have in several of my classes
Dr. Bruce Bugbee dropping knowledge? You know I'll be here family!
Thank you for taking the time to share your work. This is crucial for science based growing. Some people would pay a lot of money for this type of information, and Dr Bugbee is on here teaching a masterclass for free.
at first just thought he was a stoner in a lab coat, then he started writing on the board. Only teachers write like that lol
You know bruce is serious when he decides to change pen colour
Very grateful to the professor for sharing this info with us 🇬🇧👌
erasing with his hand lol
he probably has BBQ sandals on
I almost spited out my coffee! Haha!
🤣😂😂
I love learning about cannabis from Professor Bugbee !!
I have read so many guides online, had problems with the products they sell as grow-kids..... and then I found this. THIS here really works. Thank You
Im a biotechnologist engineer and this Dr. knows the fundamentals for plant growth. I mean, its very different when someone explains you with science instead of internet tips with no fundamentals. Excellent!! Viva la ciencia ! Saluos de Chile
This Dude is my true Personal Master of Cannabis Science! Appreciated, your Honor!
i feel like I need to download this video just in case they take it down. Bugbee the weed god.
This video is highly underrated. I personally think it’s legendary.
this one is a gem . compact , scientific , simple language . the best from what i have seen . thank you sir
Dr Bugbee, interested parties all around the world we thank you for sharing your experience information for free. Apogee's prices are a bit expensive but sharing the info for free, shows that you care. I am already shaving for quantum sensor from Apogee.

@@levonstilson9032 Your statement is per definition wrong.
I come back and watch this ever so often and it always helps to refresh thanks Doc
That was the best explanation I've seen..I appreciate the knowledge that you shared and I know it will help me extremely well. I cant thank you enough..your the best Bruce..keep up the great work
Heisenberg, is that you? haha! Appreciate you share this well researched piece of information! This really helps us understanding the plant and its behaviour! Great!

.. such a fan! Mad props to Dr. Bugbee and Team. I've learned so much from the artist practitioners on RUclips, but without a scientific base, the horticultural artist is inventing wheels blindfolded. This video pulls so much together in such a useful format. I'm going to go ahead and beg for a version of this dedicated to Soil Grows. Thank you!
what light are you using? i’m alittle lost on what i should get
@@laronthomas2006I'm assuming you've figured it out? Otherwise I can help.
So helpful, you're a great teacher and quite obviously a great scientist. Thank you for your work.
Oh man I could sit in his lectures 8 hours straight. Amazing.Fine way to represent industry products also.
Thank you very much Dr. Bruce. I'm learning a lot from you which is necessary for my education because I refuse to go into debt for school. Your work is highly important and appreciated.
❤aaa❤
Thank you so much for your videos . I could watch them all day.
MATE... I love your work. It's like you know I'm listening & how to make me understand easily.
Great content & delivery thank you Sir .
i'm officially watching all of the professors cannabis videos, when i'm done with those i'll check out the rest of his videos.
Very good lecture, I would like to see one on a totally organic grow. I know the plants don't care where their nutrition comes from but I don't like to feed every day and I am experimenting with a mix of peat, perlite, lime, 2 kinds of compost and chicken manure. I have always used a regular fertilizer but this year wanted to try something different and maybe less work intensive. I hope that it comes out ok it is only an experiment but it still sucks if something doesn't work like you expect. I hope that it works out ok or at least hope that I can correct any issues should they arise. Great video and so much great information.
228 mentally challenged individuals couldn’t understand a single thing,,, keep it up Doctor Bugbee!! it’s amazing having access to this kind of professional approach about such a divine flower. Thank You a lot Doc!!!!!!!
Yeah Bruce. Definitely learned alot through your courses . Really appreciate you taking time for us . Awesome teacher !!!
Mate, as you have studied under Bruce, I am wondering the choices of media. He was very unclear about it in the video.
IDEALLY
50% Peat
50% Vermiculite
This is the bit I was not sure about:
Substitutes for Peat were Coir and Hydra-Fibre?
Substitute for Vermiculite was Perlite?
Is that right?
This video is gold!
This guy just teached how USU grows pot!
Thank you Dr. Bugbee!!!
love you Bruce! keep teaching us, your style is awesome, u are a wise professional!
It's great to see a professional video on this. It's nice to have real documented science, and not just theory. Great work Dr.!
When science meets the nature! Most informative video I've watched! Thanks a lot for your efforts!
Man it's been so hard to find more information on cannabis growing online after I reached a certain point... So I decided to take cannabis sciences. But your teaching me on a more advanced level... Man keep it up. Your dope bro. ❤
Hey there Dr. Bugbee. I really enjoyed watching several of your videos. This one in particular. I have been operating a legal cannabis business for 12 years. Most of this time I had growers doing the work that I could trust. I have paid close attention to them and how they work with the plants. I am finding less and less employees that really know what they are doing so I have taken a lead role in my gardens currently. I do a lot of what you say but one thing that stood out to me is: I have been taught to increase nitrogen in veg and decrease it in flower and so the numbers of my NPK's would differ in each stage Do you suggest feeding it the same nutrients all the way from veg through flower?
This is my question as well.
Hello guys, when pushing the plant to is maximum yields as per the advice in the video, lowering the nitrogen in flowering will lower the EC or Ppm of the feed allowing you to push more of the phosphorus and potassium it requires for producing buds, nitrogen is in high demand in the vegetative stage but can be lowered in flower to push for maximum yields as it's not used so much for budding
Hope this helps
+1 to this question
Dr. BRUCE BUGBEE IS A TRUE GIFT. THANK GOD FOR NUGSMASHER, SO COOL TOO BE YOUR OWN CONSTRATE CO.
I've seen in a few other videos some people (Harley Smith being one of them) saying that you can put your plants to sleep by going all red light for 15 minutes at the end of your daily light cycle. I suppose it would be imitating sunset but I wanted to ask if you had any thoughts on this or if you and your team had looked into maximizing sleep cycles? It would seem like getting your plant into it's sleep cycle and shutting down photosynthesis quickly at the end of day would allow the plant to switch over to consuming the excess nutrients from the day to grow the plant. If all those nutrients are used up, could you wake up the plant with the same flash of red showing sunrise?
You went into different light spectrums briefly but I wanted to ask about a bit more detail on your white +red recommend. I want to understand what the extra red is doing and what benefits you've seen from doing so.
These are great videos and it's awesome to see cannabis research going on at my alma mater. Please keep them coming I would love to keep up with your progress and learn more about this fascinating subject.
in one of his videos about cannabis he said they dont need a transition time.
Thank you Bruce. I just can't get enough of your instruction.
Always love to see the uploads! Thanks for sharing your knowledge and showing us around your spacs.
Are you able to share any of your other methods or procedures? I've got a few plants in my Canadian garden that I would like to grow to their maximum potential.
Are you using the same EC and NPK ratios throughout the lifecycle; vegetative and generative?
When you don't get to go to college this sort of lecture is just priceless. I wish he did an extended series of these with all the science and material.
Dr. Bugbee is about to announce a 2022 version of his cannabis class. They are still finalizing the details, but you can find more information at www.cannabis.usu.edu and you can also sign up for the mailing list at this link: forms.office.com/Pages/ResponsePage.aspx?id=my81rGProkyc-fTEAEfO_49cb10JTAlJg8TrIOfBdrBURFM5WlpUWEtFME85OFgwMVExRVdCQlEyRi4u
@@ApogeeInstrumentsInc youtube never told me you messaged me this. I will be signing up for the next semester no doubt, thank you!
Fantastic information.
Would've loved to hear more about nutrient scheduling.
Thank you Mr.Bugbee
Great video...but ambient (~400ppm) is only going to be useful during veg or flowering with lower light. At 1000-1500 micromols you should be supplementing CO2 at 1000-1500ppm. Temperature, nutrient concentration, light intensity, and CO2 concentration should increase in unison for maximum yields.
Thank you Dr! You’re a gift to society that keeps giving❤
GO BRUCE!! Thanks, Thanks for Being on MIGRO as well.
Migro announced some kind of co-operation with Dr Bruce.
Seen him on it.. shanes a cool guy too.
I watch you when I'm doing to much and I need to slow it down keeps me in line thank you
Fantastic video, I'm from Canada and I'm trying to fine tune my growing techniques now that it is legal to grow at home. Currently trying my first indoor grow now. Keep making videos and I'll keep watching them!
Cheers !
How did it go?
Peat is a bit acidic for most plants - I always use it but always amend it with some ashes to bring the PH into neutral range. Other things most people avoid but probably shouldn't include clay and sand. Clay does a wonderful job of retaining moisture during dry spells for outdoor plantings especially. Sand (washed sand) is also excellent for keeping the soil from clumping and becoming waterlogged and ensures good drainage and aeration of the roots. My favorite amendment is worm castings. These will have baby worm eggs in them so your soil will quickly develop it's own worms and their worm poop is the best nutrient ever invented. So the final amendment is kitchen waste compost - everything from banana peels to old fridge leftovers all go into the compost and the worms love compost mixed in (their favorite food).
Another fantastic video! I'd like to know what the maximum recommended DLI is when not enriching with CO2.
@John Jacob Jingle Heimer Schmitt many could say those things are hard to acquire in wild... mushroom growbags are e better option and easily attainable in nature where most humans live. Plastic bags are all you would need not free from a store or sadly the wild its all over
Photosyntech I find that without supplementing CO2 the maximum intensity at the canopy should be 500-700 micromols/second which is a DLI of 21.6-30.2 mol
I've been running 500 watts of lm301 led in a 2x4 tent in a custom made bar fixture for a year now. Room temp is 78 with tent temps at 83, humidity at 60%. No co2 at all, no deficiencies. 10 bars of photoboost strips with 2 meanwell 240 drivers. The plants can get within 6 inches or less without burning and I've got great yields. The trick is to test your runoff. If your ec is rising, then make your solution more dilute until runoff is what you expect. You can run 2000 ppfd like this. That's what they do outside, there's no reason you can't replicate this inside as well. There is no co2 enrichment outside, and inside it is elevated already.
Great insights, thank you doctor.
In the past, I did exactly what you have said here to do with amazing results.
Gorge Cervantes and Ed Rosenthal were my teachers and the information was solid.
Were in the zone now and have come to just mimic nature as best we can and the plants basically grow themselves.
Thanks for the awesome video.
Thanks for always dropping knowledge! I was wondering if Dr. Bugbee could do a lesson on clone propagation. To show us environment and proper techniques. To bust myths or confirm 45°angles make a difference or if a node is required at the end etc.
The reason for 45 degree angles is just to increase the surface area for root growth. It isn't necessary but can help. Cutting at or just under a node can help because there are more auxins at these areas of the plant, but the propagation method you use will determine how much this has an impact overall.
I fucking love this man, Im experimenting with my first batch of plants home grown and this kind of content helps so much. I've been watching videos of experienced canna growers doing their thing and its interesting but this takes the cake because its an in-depth explanation of the rundowns the youtubers give on the science . Thank you for your service Mr Bugbee
He makes me wonder if im just doing everything wrong.
Probably
Thank you Dr. Bugbee for an informative video. Im a 2nd year masters student at Kansas State University doing research on high CBD hemp. This is informative and will help with statistical data on our grow for next year to be able to quantify yield data effectively.
Great info, as always! What type of lighting are you using to grow your research plants?
Viparspectra 300’s
Lol
Bruce uses hps dual spectrum
Flowering and vegetation
The light used is irrelevant. He states to use whatever the most economic method possible to hit the target DLI. Max umol around 1500 for peak production.
I think his entire recipe is based off hitting that 1500umol or 60DLI mark.
My question is, does he use the same nutrient solution mix throughout the entire grow? Is there a ramp up?
Thanks for all your hard work Mr. B my family and I learn something from you every time we watch. Salud!

Thanks Doc about the information, Doc may I know about nutrient solution in flowering phase ? hows the dosage ?? Thanks if u reply :)
Was the 20-10-20 for veg? I love how he was talking about lifting the pots and knowing. It helps you move along faster having that skill. Also, Dr. Bruce is most definitely the man!
Yeah I want to know too, if the 20-10-20 if for veg only….
What about the NPK levels for the flowering stage???
I wondered the same thing... But i think he Means all the Way Thru wth 20 10 20... I was thinking 10 20 20 idk... All i have though is 15 30 15 for Flowering...
watch Harley Smith videos. He talks about applying a general fertilizer, which this is, and then "spoon feeding" the plant at different stages to give them just what they need at that moment. Also very informative.
have watched every video religously, several times over. this man can show you everything you need to know about growing canabis as well as lots of other stuff. hell he feeds people on mars!!!!
Is 20-10-20 fertilizer used throughout the entire grow or is a different NPK used in flowering? Thank you
I forwarded this question to Dr Bugbee and he sent this reply:
We use the same 20-10-20 solution throughout the life cycle. The optimum input EC is about 1.5 milliSiemens per cm. It is particularly important to keep checking the leachate from the containers to make sure it doesn’t get too high or too low during flowering. The optimum electrical conductivity for the leachate is between 1 and 2 milliSiemens per cm.
These are typical units of EC meters; and these are the units of the Hannah, model DiST 4 meter www.hannainst.com/hi98304-dist-4-ec-tester.html?gclid=CjwKCAjw95D0BRBFEiwAcO1KDDtJngMK_6G1yJJ_g8As1bQHl5nAsTT0r-4WNOtRjv9nLX33NxB3ERoC3OwQAvD_BwE
The Hannah model DiST 3 reads in microSiemens per cm. The optimum on this meter is thus 1000 to 2000 microSeimens per cm. Either meter is fine, but the DiST 3 over-ranges at 2000, so the DiST model 4 is usually a better choice.
The exact fertilizer we use is Peters Professional 20-10-20 - Peat-lite special. The Peat-lite special has higher levels of micronutrients than the general purpose 20-10-20 fertilizer. The higher micronutrient concentration is beneficial-as long as growers keep the overall EC from getting too high.
Here is the link to a technical paper I wrote on nutrient management:
www.researchgate.net/publication/284231562_Nutrient_management_in_recirculating_hydroponic_culture
@@ApogeeInstrumentsInc In many situations, one powder is not enough because the calcium cannot be part of it. Bruce has the calcium in the media already so he's ok. In my case, I am in Coco and perlite without lime in it. (though it is buffered with Ca and Mg). I was recently using another full line of nutrients with RO water. How ever, I realized that I can leverage the quality of my tap water. It comes in at 50 ppm Ca, so I can reach my calcium requirement by mixing an all purpose blend like 20-10-20 in it. It has carbonates too which are beneficial to buffer the solution and make it resistant to swings in the media. I just need to add acid to bring the pH to where I want it.
@@ApogeeInstrumentsInc I could not find Peters or Jacks 20-10-20 Peat Lite in Europe at all.But after long search i could find "Gobbi 20-10-20" from Italie , what meets the specs from 20-10-20 Peters Peat Lite exactly.Thanks for the knowledge!
@@ApogeeInstrumentsInc Serious question. I decided to try out this method, and when I water the EC is always higher than what I put in. I tried testing each substrate component (I replicated the one in the video, albeit with different brands), and each individual substrate seems to have little affect on the EC. But when they are put together, and I am watering through, the water is coming out with EC of between 2-2.3 mS/cm, even when reducing the input EC to less than 1 mS/cm. I suspect there is a ionic reaction taking place, but I have literally NO clue. The plants seem to be doing ok. Perhaps in the video, you are supposed to take into account the delta EC of the mixture, but it was not mentioned?
Project NEMESI5 Depending on your media, you may need to flush it before planting. As far as build up over time. Water more and more often and your run off will be more consistent. I’ve lowered my ec to .9-1 ec and have been getting great results. Your light intensity, humidity and temperature will also change how the plants uptake nutrients. When it’s dryer, the plants transpire more water, leaving nutrients in the soil. The same thing happens when light intensity is too high. You can have complete control over this by understanding how it’s all connected! Super cool stuff.
Another fantastic seminar Bruce (U.K.)
Does this also apply for hydroponics? Or what would you advice for hydroponic indoor growing? And is there a way how to increase CBD in spite of THC? Thanks.
To increase CBD just wait longer to harvest. Get a microscope the more amber pistoles you see the more CBD.
@@divineshrek That is CBN, not CBD.

seriously people..hes telling you how to grow medicine efficiently..from the type of optimal soil, how to make it, what and when to feed it.
Do you feed the same during vegetative and flower? Doesnt weed need alot of calmag, does this fertilizar has any?
In case anybody is making note of the measurements, I would like to point out that at 36:36, the unit of conductivity on the meter was shown in mS/cm instead of mS/m as stated by Dr. Bugbee on the whiteboard.
