Huh? A PVC pipe for each hoop costs $1.60. 100 feet of 12 ft poly costs
$27. The clamps will cost you another $20, and you have to have some
bricks to hold down the poly on windy days (concrete chunks will do as
well). If treated well, the poly lasts three years and the clamps and
hoops last forever. You are looking at $15 per winter harvest.

Works if you don't live in a windy area. It's easier to hold down the
poly than to keep it from tearing. Hoop tunnels 2' or 3' may work
better in windy areas.


I live in a fairly windy area. It took me a couple winters to get the
tunnels down pat. You need clamps, double clamps at the end of the
tunnels, and a smooth tunnel with some poly laying on the path, wieghed
down by bricks, so that no air can get inside. I never had a blowout
when there is deep snow, it seals the tunnels perfectly.
