hi....well first of all i have a 4 foot tall box in a closet thats 2x2 feet with 2 plants....theres a fan in the box always on but its still too hot...im using cfls but they do still get warm.....since the box is closed and the closet is closed there isnt much ventilation...i started leaving the closet open hoping it would help. but the box itself is shut to trap all the light if i were to get a fan and cut a hole in the plastic....would i aim it to blow in new air, or blow out old air? or would that not help, leaving me to buy 2 fans to blow both ways?
