removing the dehumidifier lowered the temp in the tent to 88 degrees which is fine with me. i may try to vent the air out of the basement through a window. maybe construct a box to fit into window seal and blow air out from the lights. ill also look into some a/c units for the future.
He's using Co2, they like higher temps.Are you aware that the rate of Photosynthesis is greatly reduced above 72f, and over 80f is considered stress, and will require your plants to acclimate.
