The plants themselves. I've overwintered habaneros before in my basement and I feel like I could never keep them warm enough.
I could see where the temps would be a struggle in a basement. Since this is inside my house, they don't get colder than what we have our thermostats set to at night and during the day the LED's provide a nice bump over the rest of the house temp. I am in the "ideal range" for temps, but on the lower end. Lows of 70-73 and highs of 77-79.
