Great video straight to the point.
How does CO2 affect the optimal temperature? Since the most efficient way is to slowly increase CO2 EC and PAR... would be optimal to do the same with temperature or keep it at some point?
Thanks!
I think you made the most effective 6 minutes of grow information i have ever came across.
Agreed
I have ever COME across
I think the technical aspects,was ott,as to contemplate reaching that levle of technical pro-ess with a grow,you should have alot of grows under your belt,and if you don't know by this time about your plants,rather than seeking this level of technical input,I'd stop growing! I think your optimum audience is better aimed at novice grower's,with a lower technical aspects,
@@timp8472 right. It’s a good video but not that good!!!
These vids are the definbitely the handiest I've come across on RUclips. Top work! Many thanks. :)
I often come back to older videos and refresh 😅 my brain. I have learned so much from this channel!
Thank you so much for presenting data. Most of the grow guides on you tube also give great info but without the data its hard to make informed decisions on how to fix your grow.
For an Irishman you make things sound complicated, l got my information,,thank you, it could have taken 2 mins though, hey ho cheers keep safe,
Excellent video Shane! I just subscribed. Thank you very much!
love how your always medicated in videos👊🏼, stay you Shane, solid
Big up Irish man, great info as always bud.
I would love to see an updated and expanded version of this video. Maybe combining some of your other experiments into it, or just a real world demonstration of the research.
Everything I wanted to know in one video. Thank you
Thanks, Shane! You're a goldmine of growing information.
Much Gratitude and Appreciation Beautiful Souls
Good video, fun to see that this information is clearly 5 years old. Co2 and par levels have gone up verry much since then.
Hi your the man well done awesome I have learnt a lot a massive amount
Shane...awesome video...keep them coming...fyi..light intensity is reduced by a square value and only a 50 percent in height increase will reduce par by 100 % percent
Good video, good information. Happy Thanksgiving to you and yours. ✌🏻😎
Excellent video thank you for all the information you put out for everyone I have been subscribed to your channel for about a year now and you you have taught me alot so once again thanks and please continue to keep posting new content and information.

very informative and straight forward, i like your vidoes man
I love that youre usimg a pier reviewed paper. I took 4 mycelium and coco bags and opened them and put them in a tote. Now i just feed my mycelium oatmeal. The co2 stays at 1750 as suggested by utah state Bruce bugbee and harvey from npk university videos. The relative humidity is in the high 80s and so i need to vent the humidity off while retaining the co2. So enter the dehumidifier. Now i have a terarium powered by led only light and mycelium farmed co2.
Awesome! What mycelium/coco products did you use?
Great information on growing plants indoors.
you got straight to the point
I can't wait till may I throw seeds outside and they take off here in Arizona
you're looking like a Japanese sniper in this vid Shane must have been some bang of those "tomatoes"
oh my god theyve infiltrated
😆 thats hilariously awesome 👊🏼, copy right that shit
That's why I started to watch Shane's videos originally. He always looked so fawkin baked. I loved it and still do.
good video for beginers but you left out humidity, when i first started it was a problem not my par or c02
Great knowledge thank you watching from New Zealand 🇳🇿 😊
Love this info dude is on point
Great info, thanks!
Great video cheers Shane 🍻
I have been wanting to add an LED some where in my grow set-up. I have been saving for one your lights are amazing for the indoor grower thank you for making lighting for the home grower cant wait to try one of your great lights
Hi. Thanks for the nice comment. Email me and I will try to help you with a deal on a light. Thanks again. Shane
MIGRO all the led lights I have seen say that they need to be switched off after 5or6 hours off use & need to cool down for 20 mins are they all like that ??? so for a 600watt bulb I would need 4 300watt 3leds lights and alternate so some can rest is that the idea or can u name a led lights to replace my 600watt 😎🌲
Hello. You don't need to switch off LED lights to cool them down and you can switch them on and off quickly.
To replace a 600w hps the MIGRO 400 will give you more light and a better yield. Thank you for your comment
Hello, Shane. Thanks for the informative video. It seems like Migro makes a very quality led light solution. I am in the researching process of purchasing a proper led light. So far I like what I am hearing/reading. What would you recommend for a 10 plant grow in 5 gallon smart pots? Thanks again!
Hello Sean. Sounds like a 5x5? I'd recommend the MIGRO 600 for grow that size.
Very nice, clear and succinct.
Informative video! Good stuff.
The best man of all the time!!
As he stated eact strain is different. Some only perform high altitude so light nuits or temp won't have such an affect as others
Great explanation of PAR, you seem to have partook of ... Happy.
Great info. Exactly what we are finding
Thank you!
Thnx for passing the knowledge .
Great video. Thanks. Cheers
Co2 is heavy therefore falls to the floor. If you have your exhale co2 bag above a fan , it will be spread throughout your grow tent BEFORE being sucked through your exhaust , therefore it does not need to be closed circuit.
great work thank you
Good stuff 👍👍 2 thumbs up.
Thank you for this Video 👍
Excellent video...thank you
Great video. Migro
Cheers Dude!
Thankyou for the information
We’re going to be living on a boat and want to grow some basic greens and herbs. Do you think this could be successful? How would you suggest going about it? We’lll be in tropical climates most of the time. Love your channel!
Thx for the video! Excellent content! How much does RH factor in?
a nice reference to reinforce knowledge learnt Thanks MIGRO
Anthony Demitre migro for the win!
I have a co2 tank and controller in my tent. I exhaust my tent with an in-line fan into the room. I have no problem keeping my co2 1200-1500, but s 10lb tank lasts me less than a week $$$
start brewing beer :)
Hi Shane. You do great work. I totally find your videos comprehensive and easy to understand. The heat gun trick, awesome! I grow my garden outside for almost 4 months. I start my plants in early June and bring them inside when the Autumn rains come. The plants are 5-6 feet tall. This year 13 plants! I grow them in 8 gallon grow bags so they are movable. Going from real sunlight to LED. I have 5-6 years of this method, Always successful. But I always worried about light burn and setting distance. You just provided me with the tools to set this variable, thank you, thank you, thank you.
Jeff from Seattle USA.
A hard to answer question for me is the optimum 850 max par study and if it was done on a 12-12, or an 18-6? Also if 12-12 is max 850 par than can I run 8 on 16 off at a higher par for the same DLI level? (est 1100-1250 par). For now I just leave it at 11 on and raise it to 850, then taper down to 10hrs in the last two weeks for natures DLI curve to preserve terpenes. I use 12-1 and it recommends 8 hr flowering as cannabis is a short day flowering plant. But then DLI and this max 850 par has me wondering if its possible without co2, as cannabis grows at night and can benefit from longer nights, while studies show it's done taking up light after 8 hours.
Welldone migrow best brand so far
I will have a tent setup indoors but there is no way to do ducting and getting the external air in or out directly from the tent. So my question is would it be ok to just circulate the air in and out of the tent indoors? The house itself is big and the people living in it providing co2 with additionaly multiple daily opening of the windows with fresh air should work right?
Hi sir can you use a smart plug dimmer to dim a led grow light I've searched everywhere and can't find any clear answer
Any ideas on what the temperature should be in a underground shipping container grow room?????
You are great! thanks for your videos :)
ruclips.net/video/eqLeh__itgE/видео.html
Well done, thanks a lot.
Btw you need a shop and a distributor here in Canada, there is going to be a huge market in a less 8 months the cannabis is going to be legal and we will be able to grow at least 4 plants each. And that without those who has a med licence like people like me....
Big market to come...
Way to go MIGRO for making great products!
Thanks for the comment. We ship out to Canada every week now. You Canadians like your tech it seems!
MIGRO absolutely, but mostly we love great services. I can wait to get a pair of your lights. I will be placing an order soon.
Should I get a par meter or a lux meter for my hlg 260 watt v2 grow light?
Simple easy useful knowledge, cheers 👍
Thanks mate god bless
I just got the grow300. What's a great but cheap meter I can grab up? Thanks
thank you good sir
Some really great ideas,I will have to give it a try.
Great info, if I watched videos like your putting out now then I wouldn't have made half the stupid mistakes I did when starting out👍
Think I'm going to have to supplement with some form of co2 as I'm just recirculating air and not pulling in fresh air.
In a small grow area the co2 bags are a great option.
Thanks I'll put them on the list👍
The Budget Grower
Sorry my English ...
I'm getting air from outside a window ..in a urban area !
Do you think I have god co2 level ?
My temperature is never up 30°c
My humidity is about 25 the low to 35/40 the highest !
My grow room is 80x80 and 160cm
And I'm using an HPS 400watt dimmable and a led 130watt of actual power !
Normal air is around 300 to 400 ppm and is more than enough for your grow man, supplementing with added co2 is only beneficial if you have a sealed grow room and the temps are at 30 degrees +👍
Hi Shane how many plants can I put under a 600w lumii black hps kit?
Just found you. Keep up the good work!! New sub.
good stuff... Is there an update that takes into account VPD?
I've been looking at upgrading to l.e.d lights but I've read people have experienced smaller yields???? I dont quite understand how as you are using the correct monochromatic light the plants need anyone got any views on the difference between lights an there experiences only reason I started looking at the l.e.d lights is for cost efficiency as obviously running l.e.d will be cheaper
thx shane
Would a candle add CO²? If I don't leave it in there more than 15 minutes,?
than you for the info
What is the optimal temperatures for a flower room?
nothing new... but you're on the good track as a marketeer... good job!
keep up this good work for ''simple'' consumers to attract to your product(s)
We all had to begin somewhere! Remember how confusing it was to get started? Especially before the internet how to's (if you're unlucky enough to be my vintage lol)
These lights are no joke.ul soon eat ur words;) top work shain pure class.happy growing every1;)
Can you please help me with my drivers on Mars Hydro TS 3000 the older model ones with I/o and v/o with a screwdriver
Do you lose micro moles when lowering light intensity, with about 700-800 par levels?
Wow... This was back when atmospheric CO² was only 370ppm. It's something like 413 right now in 2020.
great
We need to burn more coal globally to maximize growth imagine that worlds hunger problem solved
@@matik4165 I don't think it'll work like that given global warming and the changing climate. It'll be starvation for millions if not billions in the long run.
I was kidding but ok
With adding co2 the chart u posted didn’t go past 700 ppm. At what point does the growth rate start to level out? What is the best cost effective amount of co2 to add? 1,000ppm? 1400 ppm?
How do one handle the heat and humidity in an enclosed room.?
Great video! Question: I am growing Peppers under a Spectro Light Blast 400w. But the fruits on all the plants are half the size compared to my outdoor plants. Is it correct that the amount of light hours should drop to increase frutation? And should there be a difference in night and day temperature? Thx greet Gijs
Look on google. You have a wealth of information at your finger tips
So my room is sealed and I keep the co2 anywhere form 1000 -1200 I thinking maybe 1500 when going from veg to bud. With a Humboldt indica strain. They seem to be loving it. Would u raise or lower co2 respectively? Nice vid. Thanks
I don't understand why u need 60 times x hr renew the inside air. To decrease temperature .
If I use air conditioning inside the room set at 25 C degrees and keep close and inject CO2 . Is this a way to keep the best indoor condition ?
This is very good
Can you add co2 when fans and lights are off?
Great video. I want to do a test of ambient c02 vs c02 levels in a living space ie bedroom/house/apartment. I wonder if the increase in c02 would be significant enough to benefit the plant or if it would be negligible.
Did you do it?
Acording to the article he reffered to: "Furthermore, elevated CO2 may increase photosynthetic carbon assimilation and may accelerate plant growth and potentially improve productivity. Indeed, a doubling in CO2 concentration increases crop yield by 30% or more, in experiments conducted under close environmental conditions such as green houses and growth chambers (Kimball, 1983a, b; 1986; Cure, 1985; Poorter, 1993; Idso and Idso, 1994)."
Co2 is only good if your in a sealed off room. Other wise don’t waste your money.
Do you have any advice on maintaining these relatively high temperatures in cool climates? It seems impossible to heat air (cost)effectively when you're expelling it once a minute.
When you do recirculate air, say your intake and output are connected to the same indoors and heated room, would that not cause harm or stress to the plants by lack of actual fresh air?
Even the most efficient grow lights emmit 50% heat. There is plenty of heat can be used to keep the temperature up during cold periods. Extracting low in winter with a high inlet will help. However during cold periods you are correct you must lower the extraction rate to maintain temperatures.
Intaking air from inside an occupied building might be good during light time but sure it is bad during dark time. The best balance comes to intake from outside no matter what the outside conditions are. If you you have your room/tent set up properly it will autoregulate easily.
Why is the air bad at night?
@@MIGROLIGHT During light time more CO2 is needed thus intaking from a room might be better than outside. During dark time more O2 is needed thus intaking from outside would be better.
Usually its better to intake from outside as O2/CO2 balance during day/night is better for the plant than inside air balance.
@@arnauvizcarramiserachs6318 It depends a lot on the outside. Your breathing create a lot of co², 1000 ppm is not rare especially on winter with windows rarely opens. So intraction from a livingroom is the most effective way (except co² bottles in closed room/tent).
But even in that situation, 1000 ppm = 0.1% while O² is about 20%, so I think the plant has plenty O² at night.. I will check this to be sure.
3:05 is this information taking VPD into consideration ?
A question: In a closed environment with plants, does raised levels of CO2, in itself, lower air temperature? This provided the input light energy is constant. Thanks!
Co2 isnt necessary unless the light is hot which would be from high par. It will heat the leaf and bud regardless. You want to add co2 in buding stage if you have a nice high par light. Check leaf temp and keep your leaf temp about 80 humidity 70. As long as your leaves arent stressing your golden. Keep your pots between 68/72f at all times.
Co2 level after a night sleep in a small bedroom is around 2k to 3k ppm in the morning ;)
Some guy did this test. It was a little over a 1000
What should Leaf temperature be?
I'm pretty sure you can fill a 10x10' room with CO2 and it would take a good 8 hours for the plants to lower those levels to atmospheric. You don't NEED to remove entire room volume every minute... thats required in a lab/clean room maybe... not around some plants I don't think. Mine seem to grow fine anyway with just a few full exchanges of air per day... then I can keep CO2 high in that area for a good 8 hours a day.
test showed that square metric rooms with 1 !! refreshment a day did not suffer in veg
if u don't have co2 monitor u are guessing at ppm 1800ppm is optimal for veg
@@jeanninegrant5959 1800 is definitely not optimal lol that's too high even if your PPFD levels are above 1500 and your temperature is perfect. Too high for vegetative. Did you not watch the video??
Blanco Escondido I have seen no difference between 1000 ppm to 1500ppm just wasted gas
I think you forgot about humidity because that along with temperature control the rate of transpiration. You can have everything else perfect but if you mess up too bad on the VPD you will fail to succeed with your grow.
I have 16-23 celcius in my box..... is that very bad?
Is a 75 watt led hanging grow light good ?
Great info thanks

Shane, grab a bottle of water my dude! I love how lit he looks while just spitting out knowledge!
Funny you should say about bringing natural higher levels of co2 from people sleeping in the same building as a place in london out performs a place in the suburbs both same set up and same plants except, suburbs = 1800 to 2000g london one 2000 to 2400g all ways breaking records down there ,and I put it down to higher co2 levels as london is highly populated
From an HVAC point of view 1 air change per min makes no sense. What about lights off when plants dont use CO2? Or the humidity or temp outside are highly out of spec?
You save sooooooo much money growing your own
That's what my channel is all about ;)
