Hypothetically if I decided to grow some tomatos in a 3x3 grow area 4' of grow height from top of pots to 6" from lights and I get bad heat build up how do I vent it. Above is the attic and I don't want a ton ofvheat build up in my attic. Outside the closet is my bedroom, I dont want a ton thier either. Lights would be two 400 watt MH, I already have these and dry testing the room got way hot. I dont want my tomatos to get heat damage. Is using a blower to blow into the space between my drywall a bad idea? Will that cool it down enough?
Also I saw some HPS bulbs that can be run on MH ballast, but the ones I saw were 430 watts and my ballast are 400 watt. Are their 400 HPS bulbs that can run on 400 watt MH ballast?
TIA
