Finally! Today I had an afternoon off, so I decided to tackle my nearly-complete hoop house project. I strapped the pipe to the frames, screwed in the wood strapping pieces on top of the pipe, and walked over to the Farmers' Union to see what kind of plastic they had. I probably would have finished tonight, but ended up talking to my next door neighbor for a while. I'm so close, though! The icky part will be shoveling mulch into my parents' trailer and then into the boxes.
These houses are a modification of the hoop houses that have been going in around town as the Portland Permaculture Meetup folks hold work parties. I made my boxes in 2 sections out of whatever wood I had left over from various summer house projects. I can't wait to try these out this winter!
