We want to keep some greens in the garden going a bit further into the cold months, so are going to try using a row cover over the kale, chard, and lettuce.
We’re trying to keep this very cheap and simple, as it’s very experimental. So the ‘ribs’ of the hoop are 12′ lengths of 3/4″ PVC, which slide over ~2.5′ wooden dowels pounded into the (not yet frozen) ground.
Seems to work — now we just need to figure out how we’re going to affix the covers to the hoops.
I’m surprised you were able to bend the PVC that much. Can’t you simply zip-tie the cover to the hoops?
