I built mine in 2 days by myself but it is 12x40 so a bit more manageable than a 20ft wide. If you sell the produce you grow you can pay off everything really fast. This first year of my greenhouse produced 250 lbs tomatoes, 71 lbs peppers, 1675 cucumbers, and a couple pounds of tobacco. Most of my cucumbers sold through our co-op for $1/ea which nearly paid for the greenhouse materials. I just put the S9 in but by the halving it will have just made enough to pay for itself.

I am creating a fresh cut flower farm, I have 6000 snapdragons started, and building a few low tunnels this weekend.
It should put us in positive cash position into the fall to make the investment. Our most scarce resource is labour. I am still doing the fiat 9-5 and pulling 3-4 hrs night shifts working 2 acres
