Big respect to both you on behalf of everyone on here who watches your great videos
thank you very much
I hate it when a great product is too expensive for me.:)@@MIGROLIGHT
Well said my friend
This guy has raised my game big time! Mad respect..
same here
yup, cleared up many myths and made me understand some fundamentals truely.
Great to hear, makes it worthwhile, thanks for the feedback and best of luck
big ups it's all you mate you wanted to learn more and you seeking it out
I just aquired one of your PAR meters and it makes it soooo much easier to adjust light intensity and height above the crops. It eliminates the math errors w lesser meters that must be converted.
Thank you Doc, one of if not my most important tools.
I feel Dr. Bugbee is going to change my game too.
Thank you Shane and Dr Bugbee.
Bruce bugbee is the man
With the knowledge of
The plant.
Great Video, I always love listening to Dr. Bugbee. 🔥🔥
“So anyway we started blasting them” 😂😂
@25:13 LMAOOO
this guy is a legend
2 guys I've spent hours listening to. Great questions for the Doc, well done!
Thanks dr. Bruce Bugbee, you are needed in this life 🙏 Great work 👌 and thanks Shane 💯👏🏻
This was such a great watch. Will be coming back to this one numerous times, no doubt. Cheers chaps 👍🏻
The Master Dr. Bruce Bugbee. Always fantastic and interesting content.
I have learned so much, in the last few years from both of you. I greatly appreciate any/all information you release. Thank you!
Thanks so much for this and all of the other info that you put out into the community! Dr. Bugbee is always great.
I really like your enthusiasm, great to watch your presentation of those stunning plants 👍☺️
What marvelous knowledge of plant growth and light
Two great minds come together!! I’m locked in on this one!
Awesome. Been looking forward to seeing what Bruce has learned. I'm going to buy a light just because you got him to talk.
In a 2x2 or 3x3 space, it is not about economics always. Its entertainment.
Second comment is. Why don't you hook a dimmer up to a C02 meter and select a preset over canopy height based on approx DLI levels relative to current C02 supply? Then it can self adjust to be even more economical for the other half.
Thanks for this episode. Always good to see Master Bugbee.
24:10 This section is nuts. I always start my seedlings low then move them, and they get that odd blistering/discoloration look on the leaves. I guess I should just let the things pop under full power. Think I might test that today. I might be overthinking this one.
51:19 This section on lighting under/in the canopy is pretty good. As a scrogger who sometimes deals with tight node spacing, I use the mylar side of old grow tent fabric to cover the tops of milk crates I use as platforms acting to essentially raise the shiny floor of my tent to be just under my scrog's canopy. Really brightens it up a bit and wont cost you much. The crates keep the circulation adequate. You could probably use something even better but I had the crates. It will also confuse the hell out of any aphids should you be so unlucky.
Hope everyone is looking forward to spring. Good luck to everyone especially you outdoor folks.
same on the seedling light sensitivity... perhaps seedlings were never innately sensitive to light, but merely adapted to the low light conditions they were started under, and then moved to a very different intensity.
@@andrewstephens8790 I was talking it over in a group today and this seems to check out. At any rate, i have 35 bag seeds in just to see how it goes. might have to ditch the lit seedling dome for a xs1500 pro or something like that.
Nice trick imma have tell this pretty damn guud grower i kno that trick n c how it works😉
I think allot of this info only applies to hydroponics. As someone that starts in supersoil and runs in living soil I have found time and again that anything over 800 in veg causes leaf stress (turning) possibly because of the overall water uptake. With seedlings I don't reduce the light intensity as much as increase distance, bringing the light closer every couple days essentially going from 300 to 700 over a 2 week period. Seems to work well. 👍
ive lined my grow room with that foil heat deflector stuff you put behind radiators , super reflective for the light
Thankyou both for taking the time to make this happen been wanting to watch this for weeks!!! Thanks again GROWMIES
So wait to give red +far red till done stretching then I can put them asleep and wake plants up with red +far red during flower I think I reading this right.😮?!
@@keithgustafson7786 ya u can I mean I use reds in veg now I do crypto chrome signaling for sunrise and then run Emerson for the rest of the day staying below 10%overrall ppfd of 660nm so plants don't bleach...been doing end of day reds for years now even run it in veg too
Thank you so much for this Shane. I have been excitedly waiting for this.
Outstanding lecture, one of the most informative I've seen in a long time. Respect.
Not a lecture. It was a commercial couched in bookends of not new information. Disappointed
I produce my Co2 with an Fzone fish tank generator for 100 bucks. I fill it with industrial grade Citric acid powder and bicarb, used by cleaning companies. 10kg of each cost me 65 bucks and last me about 15 weeks. in my 4x4 in a 10 x 7 lung room. at 900 - 1000 ppm. I do have to reload it every couple of days. As I found doubling the quantity didn't double the time I got from it. so reduced to 200g of each. Controlled by the IAQ Monitor Controller with solenoid and lights out cut off function. 140 bucks. I have to set my dehumidifier in the lung room at 10% below the desired tent RH in order to get the balance..
Thanks for sharing
Works but does not last long... most use co2 scuba size tanks, which do not last even a week, buddy... i got paid to pickup co2 tanks before in Denver every weekz heh... many tank refills.
a mushroom tent is more efficient and you get product... buildAsoil jeremy proves this (that channel and this one is the top no nonsense for homegrowers to get correct information without the salesman biases)
@@dertythegroweryou started 16 years ago but no grow videos? Why are you commenting with no evidence to talk? Everyone grows differently play boi
Très intéressante vidéo merci messieurs
Stay Safe
I love it when Dr Bruce spills the beans and this round was an absolute food fight. 🥰 Thanks Shane, Thanks Dr Bruce, your work is very much appreciated.
This is fantastic information. Thank You
I'm sold on intra canopy lighting after running it recently. The overall quality went up, and so did the yield. The upper canopy was getting 700-900ppfd of a red leaning light with far red. The under canopy was getting up to 200ppfd of a blue leaning light. The lights under the canopy stayed on the full 12 hours a day from day 21F onward.
Proven by medicropper about ten years ago, buddy... literally here on video many years ago 😅
Where the under canopy lights uvir bars thanks.
@concreter6832 no there not, i used the Mars Hydro VG80 bars under the canopy at pot hieght. They are a visibly blue light but full spectrum. Above the canopy I use mars hydro TSL2000'S. Which are visibly orange with plenty of red and far red.
Great show guys got a whole lot of info there I definitely have to come rewatch this on to get it more to sink in
I really enjoy your interviews with Dr Bruce, I've been growing for 10 yrs or so and learned most of what I know by making mistakes from bro science, now my grows are are solid but I still watch your vids to keep up with new science THANK YOU for what you do
Don't completely discount bro science and learning from your mistakes. My most favorite bro science guy was from my hometown in Brantford Canada. He was a deaf/speech teacher named Alexander Graham Bell who invented the telephone.
There are some New Yorkers who claim he got the idea from an Italian immigrant who had a working phone in his home and was visited by Bell but it's never been fully proven.
Bro science is great especially when people like Dr. Bruce share the real science so we have knowledge to work with. I created a huge pest infestation a little bit by accident in my outdoor grow shed with my first crack at RWDC and it was a ton of fun learning all the different and even experimental ways to kill them.
I love listening to this guy .
This man is a treasure!!! I need to do his course on the university
I WONDER IF HE COULD MAKE A ONLINE CONDENCED VERSION
Fantastic! content, thanks Guys.
The idea that we can speed up veg state is incredible, def want to read more about that.
same here mate 👍
Love talks like this thank you both for the amazing information!
I always had issues with nutrient deficiency. After listening to a podcast with bruce where he said he pushes EC to 6+ during first 3 weeks of flower with elevated Co2. I pushed EC to 3 for first 3 weeks and there is almost no deficiencies. Bruce is a hero
hi, as a biggener i have nutriment deficyency with my plant but i dont speak very well in enlgish, what EC mean ?
@@jdavidblais Electrical Conductivity. It is a way to meassure how much nutrient is in the water
@@christoffer6527is this only used for hydro grows?
I love Bruce he is such a kind human being with amazing amounts of knowledge and understanding. I dont think people realize how important and necessary these DLI sensors will be. As the world increases in temperature, the ability to grow gardens in backyards and random locations with limited amouts of sun will become more accessible; these sensors would be able to lyk how many people are able to grow their own food in their locations. Even people who live in apartment buildings who use windows to grow during certain parts of the year will also know how much extra supplemental lighting to give to their plants, food and herbs!
enjoying the deep dive
On this topic, where myths and pseudo-science from armchair experts abound, it's always a privilage to listen to reliable, evidence based scientific fact. Your channel and of couse Bruce, always deliver. Thanks!
I was just thinking about you today when i was thinking about what id love to do in life! And then i hop on here and immediately see you and a new video! Love it! Thanks for all your info and work! 👊🏻🤘🏻
Bugbee, The Bruce... Legend
Always a great conversation!
top tier content as usual 🤝 thank you so much
Thank you so much i learn so much here.
A Master at Work
Two men whose experience and opinions I trust and respect!
You guys are Angels...doing the lords work there brothers! Thank you gentlemen! Great as always
GREAT CONTENT!!!🙏🙌
yea my best grows are fall to winter in Arizona. starting them when its still warm and then finishing during december or january is the best grow season for me (indoor). inside the house it gets to the low 60's for flower which is great for the anthrocyanin production.
THANKS APPOGEE THANKS SO MUCH BRUCE
My apogee 610 is constantly monitoring in my tent! Good shit!!!
Amazing video thanks for sharing.
I like it a lot. Watch all buys really good quality, and the doctor is going change the way I grow guaranteed
Thx so much,,,would like to hear the prof on feeding(npk,,ppm)
Great show , great info
Outstanding!
Great episode. Oregon CBD has triploid cannabis breeding dialed in. They released their 1st triploids in 2021 I believe.. Now they have released triploids for Type 1 cannabis as well. They hired an experienced PhD to do the work.
thanks as always
In soil with only organic inputs I've found that anything over 800 in veg causes leaves to turn, and actually stresses the plants. Good info in general, but also important to keep in mind they are referencing very specific grow methods.
Humboldt Seed Company are working with Triploids, Shane. I'm not sure if they're publicly available, but I've seen video of the plants, and they explain how they do the work. Very interesting work they're doing!👍💯✌️
They are just a smaller pack of 3
I have them they are not new once you top them the extra branch disappears. It is a mutation and I personally would steer clear of them.
Thank you for great info and video. So basically I can use light mover on plants and it will be enough light ? Thank you.
A lot of people are not talking about VPD (perfecting temp and humidity per cultivar) enough, but are focusing on uvc and UVB and ppfd/dli..
when those are not as crucial as the VPD chart numbers.
56:00 🎯👌
Vpd is important
Push it to the limits
Like hey man
Thank you
--START WARM AND COOL OFF--
That explains why my best crop (16oz one 600w hps) was achieved in the coldest months and that I blasted the room with freezing temps.
A light scientist without sun spots just wouldn't be as believable!!!!!!! God bless 🙏
Nascent Iodine takes care of those sun spots Doc.
Great information 👍🏾
What an amazing mind. Great vid!
Thanks!
Amazing video !
The original Doctor Green Thumb..
Great content 👌
Yup, that’s what I do. I don’t use a dome. I use high intensity light right away for my seedlings but I keep the humidity in about 50% and the temperature is about 26 and they’re loving it.
Movin' on up! Nice work bro!!
awesome interview thx to both of you \m/ \m/
thanks!
Great interview!
Thanks for the video. Wish i was in the US to study under Prof Bugbee. Also happy to hear the health look is short term. Kind regards.
True. It is not that easy, even if you are here with much experience... the education requirement is pretty expensive and a longer degree study than most growers will ever get or be able to afford at his college(or most colleges)
@@dertythegrower yeah I didn't really think about the reality of the situation, was more a compliment 😜
You probably can. His course from Utah State University is online. Registration opens sometime this month (March) for the fall class. cost $1495.
Wow a DLI of 100 on a controlled cannabis plant. That's so bright. I can't imagine the lights for that test.
Very impressive and great content.
1200ppm co2 at 4000 micromoles per square inch per second, For 12 hours.
Bugbee is the GOAT!
Thats dr bruce from the light/soil video way back!🤙 man that was a great video
loving the content!
Mutch Love!
Thanks for sharing your Knowledge
My pleasure!
Shane bringing the goods!
I found mycrobal rock dust and frass to be so good i never check anything but leaf health ever since i started it. And DJ Shorts 11 on 13 off on flower cycle does show different phenotype expressions.
Some advocate for a 6C/10F temp swing between day and night during flower. Is 17C/63F night and a C23/F73 day a reasonable shift or are we better off opting for a smaller shift, perhaps a 2C/4F shift like 18C/64F night and 20C/68F day for example? Dr. Bugbee's emphasis on temp is an eye opener!
What the industry needs is a chart like a phase chart. including feed concentrations, dli, co2 and most importantly temperature(plant vs atmos). there balance and relationship is obviously of utmost importance and i would dream of being a golden ratio for any plant due to finding a plants optimum dli and therefor optimum co2 and feed rates. As my machinist father taught me, it always comes down to speeds n feeds.
thanks
Finally a dose of fact and science..something that can actually be paid attention too! thank you both very much as always gods within the industry 🔥💯
Great show again, thanks Shane and Dr Bugbee! If an autoflower is under 24/0 lighting but still receives a DLI of 60, will the lesser intensity needed have any effect on quality?
I bought P.E. thrasher spore syringe and knocked up some grain yesterday, along with making up some liquid culture with it. Im using monotubs, have some hygrometer and thermometers consistently monitoring. Ive done a lot of research but its definitely more information than i thought it would be. Very fun, and i figure if i can get any of these going then maybe il be downhill from here! This is my very first time btw so fingers crossed ❤
Respect 🙏🏽
thx! i learned a lot and still got so many questions. is there a gentic or strain which is the most effective concerning photosynthetical datas? what about outdoor green fingerprint; input/output? what might be the role of cannabis in a green transformation?
Keep her LIT🔥
I worked in the Cannabis industry for quite a while and agree with about everything this guy has to say.
I use a 2liter bottle with turbo yeast and 2cups sugar for co2 and I change it out every 3-5days. Leaving 3bottles hanging in my grow tent. I could definitely see the plants absorbing the extra co2 because after I didn't add the bottles to the room. You could see scar marks on the plant leaf with a cell phone microscope.
I want to do the same for my grow. Did it have any impact on smell or taste. People say this mixture stinks.
Hello Shane
Is the photobio 4 footer any good for side lighting, I saw it on an AC INFINITY tube video with the ion light 16 inch.
we have not tested these lights unfortunately
Are these measurements for both autoflowers and photo period?
How much weight from a M2? Is 2 pound out of a 400w led good? Asking for a friend
So what light or how are you getting 2300 ppfd at the top of the canopy without lgiht bleaching or burn? What spectrum
Great info! Shane could you please spec bar lights:
1) Phillips greenpower toplighting linear 2.2
2)Fluence VYPR 3p
3) ThinkGrow model-I plus
All with dimmers. I appreciate all your efforts bringing technical knowledge to the bro-science knuckle heads. PEOPLES
Love u guys
epic interview
I've been Dr Bruce bugsby for a few years now I also been following Dr Harley Smith for a while I think I probably watched all the videos and all the migro. I also noticed call migro always has the latest light measurement technology as far as the parameters new parameters that are always coming out I was just wondering since you don't have to stop all of them I wouldn't mind if you let me have one of the old ones I'd be very grateful I'm just saying I know that's how you always get the newest ones that come out before anybody else does so you got to do something with the old ones are still new to me very expensive how I treated with a lot of respect I can't afford one so I go off of Old School mathematics I don't have that luxury I wish I did do you think I can have one of those old ones you got I'm just joking unless you're really going to let me have one LOL I love the work that you do and I plan to grow old along the side of you why you do your research thanks for the up-to-date info and research I really appreciate it makes a lot of sense with Bruce bugsby how about the temperature variable in the stretch plus the fire Red and on that note with the UVC I tried that one time and I came back a couple days later my plants were starting to have a lot of leaves to burn burning all overthis was days after I use the UVC light and it wasn't even that powerful well the outcome was had a big mess to clean then after find the genetics sorry for the long comment but I would really love one of those parameters the old ones LOL thanks for sharing your researching info can't wait to see you next video
Harley is a great consultant who actually consulted on the grow in my banner... I geeked out and all the farm laughed that I talked about him after for a while... he now got hired in my local state grows commercially.. 😅 A lot of people used to look up to him like a lab grower, much like we do Doctor Bruce 😅
Bro, you only wave uvc for five seconds per day... proven to get rid of pm
uvc is simply waved over plants, once or twice per day (CleanLightNL or cleanlightusa has the limitation instructions brother)
Well I had infestation years ago when my younger days and I thought that my vegetables would be okay I left that thing on for hours lesson learned the hard way
