Hey all, its been awhile since i been on had to shut down for a lil while butb back at it now. I have. Stand alone closet i bought from home depot and mDe my rom from it. Its 2ft wide by 4ft long and almOst 7ft tall. I had to put the room in my walk in closet for stealth i rAn the exaust up in the celing between me and the upstairs neighbors i have a blower from an industriAl tube heater ( not sure cfm) as the exsaust fAn and a bathroom fan 120cfm as intake plus a circulating fan inside to keep air moving. Out of the closet i was running 80 85 now in there its consintatly 90+my plants look good but would really like to be back down in low 80 s. Any ideas would be greatly apperciated. O, an any light proffing tricks i have been just thrownin a dark sheet over the whole thing at night during flower but would like something pretier

The most important issue concerning removing heat from grow rooms is lighting,getting rid of all the heat from the light will cut heat drastically.

Heat radiates through the glass just from the light itself,this is radient heat which only accounts for roughly 10% of the total heat given off from the light,you cant stop radient heat.

What you can do though is to remove all heat from inside the reflector,if your reflector is warm to the touch then your are not pulling enough heat from the inner reflector area,this intensifys the radient heat effect as well as turns the reflector housing into a space heater.

Get a 6 inch inline fan pulling heat from the housing in place of the current fan,also connect the inlet side of the reflector to a flexi vent & pull air in from the coolest area possible.
