This was my first winter with my greenhouse. It is 8' x 16'. I bought one of those oil filled electric heaters, but it didn't keep it warm enough....my veggies were not doing well, so I turned it off. I was thinking of getting a small propane heater for next winter.
This is a pic right after I built it; it was a kit I bought from Sunshine Gardenhouse. I have since put benches along both sides. Did you build yours from scratch or buy a kit? If I had to do all over again, I would build from scratch, I think.
