i only been feeding LAB AND FPJ sweet potato FPJ hot weather plant so it does real good,but ya im impressed so far,just gave up worrying about all that shit and let um ride,,crazy as shit though,i leave that utility room door open and it stays hotter in there than with it shut,like 3 degrees difrence,so been closing door,all the cracks in and around door still pull enough co2 in there,crazy shit is,temp gauge say 85 air coming out the filter feels cool ,weird right,so im shooting that air towards the door and i have another big fan to blow heat out door to,i started them clones thinkink the heat would screw me and was just gonna clone them bitchs to it got cooler
