The local mega hardware store carries all the necessary materials. I'm using 3/4" schedule 40 PVC pipe, duct tape and some heavy duty clamps I found in the shop.
I started by drilling holes every 4 feet in the bench that runs along the top side of my garden box. I found that a spade drill bit worked well for making the holes.
Slid the PVC pipe into holes.
And within a half an hour, I had the framework finished. I used a total of seven pieces of 10' pipe and secured the top cross members with duct tape. I think nylon ties would also work nicely for holding the pipe in place, but I didn't have any. So hundred mile an hour tape it is.
Using a T-square and a straight edge, I cut the plastic to size and pulled it over the frame.
I used these really nice clamps to secure the plastic.
Now, I'll wait until tomorrow to see how effective the hoop house is.
