rikb631 Reviewed by rikb631 on . Heat Issue I have 400w hps in a 3x3x78 grow tent that's in the closet. I have a 500cfm fan blowing air out into the attic and yet I can't get the temperature down. With an added oscillating fan and without I couldn't get the temperature below 85 while the house temperature is 74. Any ideas? Rating: 5
