If I put cans or whatever, containers of water in my greenhouse without a heater, they will help keep it warmer. Until they freeze if it gets to that point. Then if I don't take them out they become a hindrance, absorbing the heat before it can warm up the greenhouse.

So I'll try something like that with my heater and 100 watt bulb on. I had a 16 degree difference this morning. 23-36. It's going to get worse later this week, down into the mid teens. 16 degrees is possible, which puts my green house, at the current rate, at 29.

That is not good. Hopefully the power won't go out.
