I was googling epi greenhouses and found this older post. I'll add what I rigged up. My shade canopy which I used for potting, was ripped to shreds within a season and I was left with this 10'x10' frame. I put metal electrical conduit poles through the slats to hang pots on. In a few weeks I will add some 30% shade cloth attached with zip ties. I also added the poles using zip ties to hang them in the actual greenhouses. I bought a lot of aporophyllum cuttings this spring, so I'm short on space. This helped and costs only a few dollars each pole and ten bucks for a big bag of zip ties.
