i have 10 plants vegging with a 400w MH in a 2 by 8 closet. What should i do to ventilate it. if i keep the doors closed the closet gets the 100's so ive had it open and its at 85-90 degrees. What should i do to ventilate the closet. It does have a double sliding doors. Also, would it be fine if i had the door open always during vegging and have it around 85-90 and when i go 12/12, close the doors and have no ventilation but the light would be off? anyways, ant suggestions for what i could do would be appreciated, thnaks.
