I can get deals on used Propane Patio Heaters right now. I guess while it's 99ยบ here, people don't want heaters taking up precious garage space. I am thinking of using propane heaters in the new greenhouse during our occasional freezes. I have electric heaters. But if we lose power, we'll be out of luck. Anyone have any hints on using these? How long would a propane tank last? All night? Is it expensive to use compared to electricity? There is a smaller table top heater that uses 1lb canisters. Would it be overkill to have two in the 10 x 12 GH? Heat rises. How does the patio heat work to keep the floor level plants warm? TIA
