I had them in my garage for veg under a 105 watt (500w equivalent) fluorescent for veg in my light proof garage. Then put them out side for 12 hours of good sun light for a week when it was getting into the low 50s at nite they go back in the garage. (high 50s in the garage)

In this heat wave they are now outside for 72 hours straight (about 10.5 hours of dark) and loving the hopefully good growing conditions 91 in the heat of the day, and low 60s at nite!
