I have a 5x5x6.5 darkroom tent, 1000 watt HPS/MH its my only tent. I have the light under a hood and its well vented with a fan attached to the end. I also have a can fan scrubing the air in the room, and a Co2 set up. The heat is gettin way to high in the room looking for the best way to keep it cool without a giantic 10000 BTU ac
Ventilation is your only solution.. What does it get up to in there? Fuck.. 1000W in that small of s space.. thats hard core man.
