Below 60F and above 90F is where metabolic processes begin to suffer greatly.."IMO" With between 70 and 80, what "I" would consider ideal. My climate is pretty arid. I'm lucky to retain 30%+ RH.woodydude said:this is another of those irritating area's where asking different people will result in different answers.
The grow guide here states up to 95 with CO2 enriched air and as low as 60 night time outside.
This is because a constant and controlled, increased CO2 level allows the plant to metabolize more efficiently. "Only" when in a totally 'controlled' environment, with increased lumens, a higher concentration of nutrients, and enhanced CO2 will 95* be considered optimal.
My target is 78deg for both veg and flower lights on and lights off 65.
My target for RH in veg is 50% and flowering 40%.
Most of the newer material I have read seems to be close to those figures since I do not have a CO2 generator.
