That outside box fan is worthless in it's current position, you are actually extracting the coolest air from the tent. The inside fan as well should be directed and hung at/above the lights(your heat source). Hang your external box fan higher and make the exit air hole around light fixture level. You aren't flowering so there are no probs with outside light interferringguys i have a problem heres a hot wave and my closet get to 33 c° any ideas i use the big fan as extractor for now until i buy one, theres a humidifier but is not rlly good and dosnt make much diference
