Co2

What are your thought on co2

I dont get it, with that much plant mass and extrem high temps and high humidity and it works.
Why Dosen it go mouldy???

Would like to know from people how work with or worked with co2.
Ist the finish product better or worse quality?

Close System or normal exhale fan

to work in closed loop you need air conditionners and dehumidifiers. both take off humidity from the air
(AC's will dehumidify the room only in cool mode)
if it's well sized you will have good control on humidity and never see any mold

co2 accelerate photosynthesis

i advise to work with burners (pilot flame) over bottles

if you vent your room you waste all the co2 and electricity

sealed=total control

Don’t bother unless you are ready to spend and work. Those bags are worthless as tits on a male dog. Focus on buying better lights. Far better return on investment and easy to work with.

Co2 is complelty pointless unless you have everything else completely optimized.
Co2 needs to be your bottleneck on the grow.
In other words, you can add all the CO2 you want, but your plants won't grow any different if they are limited by lack of light, poor ventilation, improper or imbalanced nutrient feed, ect.
