I looked at greenhouse heaters at a recent auction, but even at auction prices, they are out of my league.

I actually have an out-building that I built to contain a wood-burning furnace, which was my original design. I just need to re-build the ducts. That shed doesn't even have a front door, and would get plenty of fresh air to keep the heater lit. I'm never inside the greenhouse when the heater is running, so I am not worried about breathing the air. It just needs to be clean enough to not kill my plants.

Curious side note - I had sprayed Met52 on my aphids, and thought they were all gone, but they had started to come back. After I ran the heater for two nights until it snuffed itself out each night, there is not a live aphid to be found. It worked better than the Met52. I guess I suffocated them. I still have a few whiteflies, though. They must breathe less.
