Here's my next project. Got the yard marked for buried utilities & such so I can dig a trench and run power to my greenhouse. I will still use propane as my primary heat source, but it will be nice to run a fan without an extension cord. Have the Little Buddy propane heater (4000 & 9000 BTU) and also have a True North Caframo electric heater/fan (1500 watts with about 3000 BTU on High) for back-up and air movement. I only have a couple of weeks before the ground freezes.
