My Bhut Jolokia did ok in the cool temps last fall, but it really didn't like it when the temps started dropping in the twenties and teens at night, even though I was heating the hoop house. I finally cut it way back, and thought I'd last it. I noticed last weekend, though, a few tiny green leaves coming out near the base.
Cherry Chocolate and Pilange continue to be the real champs in the hoop house, btw. I picked a handful of beautiful ripe peppers off of them last week. The Criolla Sella and Hinklehatz aren't too shabby, either, but they're in the most sheltered part of the hoop house.
