With heaters. the temp should never go below 50 degrees, as the tropical plants don't like it. The goal was to reduce the heating costs compared to the old stand alone greenhouse through better insulation and recovering some of the waste heat from the hot tub. We should also see some savings from the ht tub not being outside, so it's a win-win. Besides, now we won't have snow blowing down on us while we're in the hot tub!
