the temp of the nutes was 59-60 F and that was during the middle of the day so i can just imagine how cold they must get at night and early in the morning... yes they were on teh basement floor but i had a heater running nextg to them but it didnt do anything. im goin to put insulation under and around the nutes and see hwo that does.. does the cold nutes explain why the droopy leaves though? i think it was just putting them in shock everytime they got fed... im gona put insulation under it so its not just on the basement floor and hopefully that will raise the temp a lil
