ok so i have a grow closet setup. 4.5 ft wide 18in. deep 8 ft. tall. ive lined the walls with mylar. i got my light yesterday. its a 55k lumen fluorecscent grow light. i can tell its heating the room up too much. i can get a dehumidifier for the high humidity but what can i do about the heat? it is a rented house so i cannot go cutting holes in the walls. i have a fan going but it just blows the hot air around. any ideas are much appreciated. also what his the highest temp that is ok for mj to grow? id say its 85 to95 or more in there.

thanks!
