Hoop Houses

Last year, we spent a lot of time and energy building a cold frame out of plywood and salvaged windows. It was only about 3 feet by 3 feet, but it worked well for us throughout the winter. This year, we are experimenting with hoop houses. Winter aside, hoop houses are great for protecting young plants from the brutal UV rays at this high altitude. They keep the soil moister longer, and keep the temperature up to encourage growth. We're still trying to figure out whether to add more layers of this row cover or whether to get greenhouse plastic instead. Has anyone been through this with hoop houses? Any wisdom to impart?

Tristan built these hoop houses out of PVC, row cover, and large binder clips. He used lengths of 1/2" PVC for the hoops, and they are anchored in stakes made out of 1 1/2" PVC. Shade cloth is drawn over the top and secured with binder clips.
