Hunterdon31-
It took 4 long days with any where from 2-4 guys working on it. This is the first time I have built a greenhouse, so next year I think 3 guys could erect it in one long day (the end frames are already made, which was very time consuming). The hoops are two pieces- so they break down to a size that would fit into a pickup.

The ribs/hoops are metal. The cover is 3 mil double layer poly (just like a regular greenhouse). The airspace between the two layers of poly is created with an inflation fan. The pressurized airspace provides insulation, decreases chaffing of the poly on the hoops, and reduces condensation. I'm am not sure how much insulation value the airspace provides, but the grower that gave me the greenhouse thinks I could maintain 50deg during the coldest months with a 50,000-75,000 BTU heater. I am planning on installing a wood stove, as I have a huge stock pile of fire wood.
