Hahahaha the fans wouldn't let me sleep at night. So I took them off and had the "tent door" open for optimal temps. The light was so strong that I couldn't sleep for more than 3-4 hours. I ordered a sleep mask from amazon and took 40 days to arrive for fuck's sake. I received it before Christmas thank God. My tent is a 2x2 though. I can't imagine having a 4x4 in my bedroom LMAO!
