Our first challenge was figuring out how to put our very fancy and expensive greenhouse film over the rough rebar casing without tearing it. We mused on using everything from duct tape to old sheets but ultimately we decided to go with pipe insulation for its durability and extra cushioning.
To no one’s surprise, he ended up finding bubble wrap lining the inside of the planter boxes. Seriously. So we ripped that out and are now repairing them and putting in some proper lining before putting them back in the frame.
