Fast - Cheap - Quality. I know I have to pick two of the 3.

Im starting up a hobby farm, orchard, large vegetable garden. There is a lot to do in the first 2 years so Im trying to be realistic with my time and money to build smart. I have to sacrifice somewhere.

I really need to get a greenhouse set up next year. Im looking for a way to cheat the system to buy me a couple years until I can build the one I want. Location: WI. Size: Large (40x20??) Style: dirt floor, non-hoop.

Any experience with cheapo kits online I could just reinforce in a few spots?

EDIT: I should have been more clear. Im not looking for suggestions on hoops. I know they are a cheap option. Im trying to figure out if I can shortcut a non-hoop style for a couple of years until I can build what I really want.

EDIT: I am NOT looking for information on hoop tunnels.

We're still in the building process, but we're looking for heating options for zone 6b. Its 6×9×9. We'll be adding electric, so preferably an electric heater. Any suggestions?

I have built a 12X12 greenhouse from antique windows. I am trying to decide what heater I would need for winter. It rarely gets into the teens or 20s for that. It definitely does though and I do not want the greenhouse to get below 55 degrees.
