There is an FAQ with pictures on how to properly monitor the temperature at the plants canopy. Try not to go above 85f at the most, 78f is better.
Zandor Reviewed by Zandor on . Temperature at plant top I have read loads of temperature posts that for the most part address ambient air temperature in the grow room. I believe the temperature at the plant-top level would be somewhat higher than the "room" temp. Has anyone any information on the temperature is as the level of the leaf? Thanks, great forum.
