Our hoop house is complete! What is a hoop house? It’s an unheated greenhouse built from steel tubing and wood with a polyethylene wrap used to extend the growing season. Ours is 14’ x 40’ and is a gothic high tunnel, meaning the ridge comes to a point to shed snow, and the maximum height is almost 10’.
The steel tubing is bent into shape using equipment designed by Elliott Coleman and sold by Johnny’s Seeds in Maine. The endwall board is removable so we can move our BCS two-wheel tractor in, and the beds (full of dahlia at the moment) are each 4’ wide with central and outer aisles. The plan is to germinate seeds along the outer walkways, so they’re wider than they would be if we were planning to use if only for in-ground production.
The end walls are both ‘scissor’ doors, lengths of steel tubing connected at the top which swing open as needed. The plastic fits into poly wire channel on the sides and wraps around the end to prevent drafts in the winter.
Before winter hits I need to fill the area beneath the baseboards and the ground with dirt or mulch, and pre-emptively patch areas where I expect the plastic to rub against fittings. And put some yarrow in to overwinter!
