i dont either. just got my air cooler in today. fuckin sweet!! i do have a couple questions tho. so my closet is going to have a veg area and a flower area. is it bad if the 1000w hps mixes with the light in the veg area?? should i keep the two areas separated all the time. i have a huge tarp i am going to put up so the flowering area stays pitch black at night. but during the day is it fine to have both sections open??
