When I lived in a cold-winter climate, I put many plants in the bedroom farthest from the furnace, closed the heating vents to that room, and put standard fluorescent lights (less heat radiating at the plants) overhead. I set the timer so the lights were on at night, both so I could see the plants when I was not at work, and so the lights would keep the room from freezing at night. One year I did lose a few Aloe to freezing. They were closest to the window. Leo Martin Phoenix Arizona USA
