I am setting up a 39"x39"x79" tent. I will be running a 400 watt HPS and ran into a question. The system will be holding 6 plants with lots of room to grow.
I can set up a t-stat to control the fan's mode, but I am trying to figure out how many CFM I should be moving to get the heat out of the space effectively? 4" or 6" ducting?
