my grow room is 5ft x 5ft and 8 ft high running a 400 watt hid with an air cooled hood,and four sets total of 8- 42 watt cfl's. it has a small dedicated a/c unit mounted at floor level. I am able to keep the temp range between 72- 76 degrees. now the problem, over the last few grows the smell has got really bad or good depending on your point of veiw.......so I bought and installed vented to the attic a 6 in can fan and a can filter 33. this took care of the odor problem. now I can not keep the temp down think I have blown the pressure in the room and along with the odor getting pumped into the attic so is most of the a/c and temp's are in the mid 80,s anyone have any idea's? thanks in advance.
