Heating a hot house
I have become the new owner of an 8'X16' hot house that I'm filling with tomato plants that will hopefully get an extra few weeks come the fall. What does anyone suggest to heat this thing? The sides and top are the wavy yellowy kind of panes. I have a small portable propane heater I was thinking of using on low, but it will not be vented. I'm not really hot on that idea. Can anyone tell me if heated soil cables could do the trick?
