Temp is one of the things that you must be able to control if you want to grow any strain you want. Right now I am running a tent of GG#4, And it prefers it warm. 70-75 at night, 80-83 in daytime. My last grow with THC Bomb, liked it a little cooler. The other thing is if tent is too cool, some strains develop powdery mildew. Some of the old landrace strains are very temp dependent. If you are in a wide open, cool basement, you can use 2x2's and put a small room around your tent with plastic around frame. Then use a small heater to heat that space. It will give you better environmental control. That's one of the great things about indoor grows; you have the ability to totally control the environment and put out the absolute best.
Good luck,RR1
