My temp sits right around 75.No intake/outtake,but I have the window open and usually the door,but I closed it and left it open just a crack cause my temps dropped to 70 the other day,so that makes sense then,the heats obviously built up,Ill keep the door open from now on.Cant wait to get my first harvest cause Im getting a good deal swapping some smoke for a tent and fan.Hey nitro your advice is much appreciated my good man,thanks!
