I built a hoop house with EMT conduit, U-straps, Polycarbonate panel strips, treated decking, gorilla tape, common greenhouse plastic, and C channel/wiggle wire. The strips of 4 in-wide PC were added to increase the surface area for the C channel, wiggle wire.

The greenhouse is 13.5 ft by 10ft and roughly 6.5 ft at peak. The main structures are just 2 end-to-end 10ft emt conduit poles. The door is a polycarbonate panel that is 4 feet wide and I got the hidges and installation equipment from fellow Maker Pipe fan Billy at Northwoods Engineered which has held up fairly well in its 3-month lifespan. The building has seen 40+ mph winds and held up in a 3-inch snow load so far. The vertical poles were driven into the ground and then attached to the decking with U straps. The left side was so as not to be attached and too rolled up when needed. A 10-inch wide exhaust fan was added recently and has been awesome from Vevor on Amazon.

My installation of the plastic needs to be improved but overall has held up well.
