I have a 4x4 grow tent with a 6 inch air cooled hood with 400 watt HPS. Supplemental lighting is 9 band 150 watt LED and two 300 watt cfl. If I do not wake up early enough or am away for the morning the HPS still brings the temps near 90 and remains there for a few hours. I have a 120 CFM exhaust fan and a 6 inch inline intake fan bringing room temp (about 72 degrees).
My question is if i install a kill switch on the HPS to turn off at 86 degrees and then on at 78, the HPS should turn on for the first hour then off until the tent cools down naturally or is opened by me, would this cause significant stress on the plants or equipment? Are the LED and CFLs enough to continue the growth cycle for the few hours the HPS is down and not ruin the flower cycle?
