Do you chase leaf temp, air temp or a combination of the two? I read so many different numbers when it comes to temps my head spins.
My top of canopy leaf temps at a measured 700 PAR under a HLG led are 72 degrees with a room temp of 80. The lower leaves are cooler. Even when I bump par up in flower, I get 4-6 degrees below room temp.
I feel 72 degrees is too cold. I can up my room temp easy enough but at what point should I be concerned with my room being too hot? At least one source claims 82 is the perfect leaf temp for photosynthesis. That would put me in the upper 80s for room temp.
I guess I’m trying to understand if there are negatives to the room temp being too high if leaf temps are good? Or should I just find a nice balance of room v leaf temp and call it good?
