I have a Rion Greenhouse and I use it as a 4 season greenhouse. I am looking for others that have a Rion Greenhouse and how they heated it during this past winter. I currently have a 240V heater that worked extremely well but was not able to keep up with the sub zero temperatures. I purchase 120V backup heater and connected it to a thermostat.

I am looking for others that have a greenhouse and their experiences.
