I have a low tunnel made from PVC bent into an arc - because it is on a 4ft wide raised bed, they all came out very even. Covered with a remnant piece of 4 mil greenhouse plastic. You can find these cheaply on web sites that sell the material to others - ends of rolls are inexpensive but watch shipping costs. I should probably tie in a ridge pole for stability in wind and snow, but it is in a protected spot. Great for lettuce and a variety of greens.
I really want a high tunnel so I can walk in on a cold winter day!
How do folks solve the issue of ventilation of low tunnels on sunny days? The small size means it heats up quickly in the sun, and I am not available to cover/uncover all day long. Does anyone have a good solution to this issue?
