Hello, If a plant only has normal CO2 (300-400ppm) during every stage up until flowering will additional CO2 (1500ppm) during the flowering stage even be worth it? Will it just kill the plant, not have any affect, or will it in fact still be worth it? Thank you!

Great answer and thank you. One question, and apologies for my noobness but what is the purpose of a humidifier if you need a dehu to get moisture out of the air? would you just not run the dehu as high to let moisture build up etc?

Anyone know or use a good brand for a CO2 burner that is cooled? I see ones that are water cooled but hard to find them in stock and was wondering if there where others.

So, I was taking a look at Co2 burners and some come with cooling to reduce BTUs (Amazing!) but as far as CO2 bags go... I see some cover up to 36sqft, etc. and some others 128 cubic sq ft... and last for many months (6-12).... my questions is.... can I just hang up a bunch of bags spread out...

My climate can get up to 90-95 degrees in summer for Michigan and with 6k watts of HPS lights will ever need heat all? That is 18k+ BTUs of heat with just the lights.

So, will a tank of any other method of CO2 delivery work for a 10x25? Secondly, are you saying 36k btu total will do the trick? (also, why not just do a 36k unit with two zones?)

Yeah, I realized this later lol.

It is a 10x25 ft room so you are saying only a burner would get my ppm up high enough? That would add too much heat I am sure. I will be getting a 3ton mini split (36k btu) and not even sure it could handle the burner addition, etc. But if using tank or bag it wont get high enough? Hmmmm if that...

We will be using a CO2 tank with timer and PPM reader etc.

I was talking to an HVAC expert and they said for grow rooms you range between an ACTUAL BTU per light of between 4-6k. This accounts typically for other things such as ballasts, dehu, etc... he said I would be looking at around 36000 BTU (3ton) unit to get the job done. Are you saying that is a...

I see some mini splits have dehumidifying capabilities. Can this work instead of buying a separate dehu?

It is well insulated (spray foam for air seals, R-15 fiberglass, vapor barrier than 1 inch poly foam board (aluminum radiant barrier on each side). No light or air gets in

Yeah but can I get vented hoods for Gavitas? I have the 1000 DE

As the 6 HPS lights are basically my heat source than with 18k+ BTUs of heat it will heat it up prob to around 120 degrees with no ventilation (this is a larger shed, fully insulated and sealed) from my calculations and with co2 I wanna get it down to 85-90 degrees but I am concerned that as it...

What is a remote unit? And are you saying you would do Window vs Dual Hose Portable?

My room is specifically 6 x 1000w HPS Gavitas and 10x25x9 room.

What type of AC is often recommended for a sealed room with CO2 supplementation? I want to make sure too much CO2 doesn't get sucked out of the room. Thanks!

My first time but the person I am with has been doing for 10+ years but also like to try and learn myself ahead of time

The funs are there just double checking on what is needed and why. thank you!
