Sooooooooooo I still feel shitty but I figured out my curling leaf problem. It was definitely the cO2 lmao, I am kinda bass ackwards sometimes and do stuff that after I figure it out seems like I could have done it in a much easier fashion. So I have done several things to increase and retain my heat and I did it all at once basically. I put all 3 of my lights on and then sealed the tarp curtain with Styrofoam annnnnnnnnnnnd put my heater on. I just assumed my heater was doing the real heating but nope its really the lights. So with my curling leaf problem I wanted to try and run it tonight without the heater, low and behold I am having to still run my fan speed controller cause it got up to like 100 in there and it is 26 outside. So that is really good news, now I know I have good insulation value whooo hoooo. I think I am prepared for the end of the week when it is supposed to get down to 5 and 6 degrees at night this weekend, fingers crossed anyway. But with the good news that lets me know I should be able to raise my lights a foot or two and put more babies in their forever homes!
