My new grow is in the basement.. it's sits at around 68F and with lights on at 75f.. my question is this.. my basement is windowless.. so I'm wondering about fresh air.. and exhaust. I have a portable aircondioner but I dont have a place to exhaust that down here.. also my humidity gets up to 90% during lights off but my portable also has a dehumidifier on it... any suggestions Mars Hydro 400 Led Ultra Lemon Haze Cyco Nutrients
