I was looking for a way to grow lettuce and spinach over the winter so made these hoop houses to fit over my raised beds. These will double as a holder for bird netting next season to protect strawberries. I was very pleased with how they turned out and they only took a couple hours to make. Also, they are very economical compared to a lot of other options I was considering. Total cost for my 3 hoop houses in these pictures was under $35 and I have enough leftovers to make another 3 for only $12.
