is it true that if you are running c02 in the room you can grow in warmer conditions? my room is running about 90 degrees with ac in the room. how bad is this?
if a room hits temps tht are too high 90F+ plant growth and (someone correct if wrong) but potency can be affected, but adding at higher temps actually increases absorbtion. instead of wanting 70-80 for a grow room you could do just fine with 80-90ish. it makes more out of ur co2 if you have higher temp bc your plant will absorb more. so yes it is true, why is bc the stomata open up more and allow more co2 to pass thru the cell wall easier, but the higher temp also speeds up transpiration (loss of water thru the process of evaporation) so i would be careful.
good luck- pc

do u have a sealed room if not what would be the pressure bleed off, for example if u have 5 psi in there and shut it off how long does i take for the 5 psi to drop off to nuthin? im pretty sure i can do the math i just need to know some things first so its accurate
