Yeah, lights on at night, gotta do the same thing here. Next week is supposed to be close to 100 degrees here every single day. Ugh. I do lights on from 10 PM to 10 AM. I tried 7 PM to 7 AM, but it hasn't cooled down enough by 7 PM, so had to bump it up 3 more hours. I feel sorry for outdoor plants, suffering in this heat while my ladies enjoy a much more comfortable habitat.
