Heating a Greenhouse?
I just had built a 7'x8' greenhouse. It has 8mm polycarbonate. The frame is made from the new treated lumber. The door is an insulated door. It has an insulated sliding window.
Has anyone tried storing containers of water in the greenhouse to help with heating costs in the winter? If so, how many gallons of water does it take to keep the greenhouse warm enough at night? I am hoping that some sort of small ceramic heater and the water storing would heat this through the winter. Also, any idea of how much this runs up an electric bill?
Does anyone use a small fan that is run by solar panels? Does it work? Can you tell me what kind of fan and what type of solar panel? Or, is using electricity to power a small fan, just as inexpensive?
I live in Missouri. During the winter, it can get to -10, 0, and often in the teens, twenties, and thirties for the temperature.
If you have used anything that helps with the heating (or cooling) costs, please share what you've done. Thanks!
I live in CA so I really don't know much about 10 below. But I do know that electric heat is drying. I would use propane. Plants do produce some of the heat in the green house. Here in CA, in my make shift green house, I used Xmas lights to help keep plants warm and candles. Keep the plants up off the ground. You'll need grow lights and they help too. They do sell rubber heating pads that you can set your plants on to keep roots warm. Keep plants bunched up together. That helps also. If your not using a section of the green house then section it off with plastic so your not havng to keep it warm. Cardboard is a great insulator on the ground and where it is not preventing light from coming in as you need the light..just not the cold.
