I really need some help. My cool tube will be here till Tuesday, but for some reason my temps have taken a turn for the worse. I came home from work and it was 99* and I thought it just might have been that the door to the room was shut so there was no air flow. So I opened everything up and got the temp back down to 84 which was fine with me for right now. But after about 20 min of the tent being closed back up its back up to 95*. Only things I have changed in the last 24hrs is I added 3 2L of yeast/sugar for Co2. So please can someone help me out?
