So I just upgraded my light and exhaust system I have http://www.vivosun.com/4-inline-duct-fan-with-4-carbon-filter-odor-control.html for my exhaust and I have a 315 LEC light. I have had the tent 2x4x5 running with t5 lights at about 80 degrees without any ventalation. After installing the light and vents I am now hitting 100. I can not vent to the outside as it's now winter and my apartment building doesn't like growing. I can keep the window open but. That's it. The room as is it is usually about 68 ish degrees but the tent just keeps getting hotter. I don't have a ton of room to be able to add more on the floor of the tent. I will add a full picture of my set up in a few hours because maybe I just need to move and adjust my venting.. but in the mean time any thoughts..
