Temperatures

:stoned: What approximately is the lowest temperature that you can grow at.. I've read like 65 degrees but I wanted some opinions. We want to grow in the basement, but I'm up here in the northeast and it might get a little colder than that. I may just wait till spring Thanks in advance !

70-75 is optimal, 65 is the very low end and will likely give you pretty slow growth. Why not just get a space heater? Also, if you use HPS or MH lamps, they put out quite a bit of heat and you might be ok. Hope this helps.
