I'm in Michigan and I'm new to greenhouse growing. I'd like to know what others are using to heat their greenhouse with. I thought about a vent-free blue flame propane heater with a built in thermostat. I'm more likely to need heat during the early spring than I am through harvest this fall. I already have ventilation hooked into a temperature controller but I still a source of heat. What are people using to heat their greenhouse with?
