Step 4: Build a Greenhouse: Step 2 Build the Frame
2) We used the hacksaw to cut the ends of the PVC pipe at an angle so that they could be easily stuck into the ground. To do this, start about 3 inches from the bottom of the pipe and cut away from yourself at an angle.
3) Stick both ends of the pipe into the ground at opposite sides so that it makes a nice arc. We placed one arc behind and one in front of the garden. We measured three inches to the left and then another three inches away from the garden corners.
4) Next we placed one 40 inch PVC across the top in the center of the arc. We duct taped the ends to the arc.
