So the wood is here, the hubs are here and I've found a site to order the polycarbonate 8mm doublewall covering from. (That's the expensive part). On Monday the 6th a local contractor will meet me and we'll set up to move the small mountain of dirt that stands between us and a constructed grow dome.
http://advancegreenhouses.com/ is a good place to find polycarbonate sheets.
We're still trying to research and decide how to form the base for the greenhouse, I'm leaning towards a small knee wall from 2X6's with a door and airlock on the North side.
