You will need 20 ft. pieces of 1 inch PVC piping for the main frame of the greenhouse. Installing them is the easiest part...let the kids help with this.

The next thing to do is install the horizontal lumber that holds the greenhouse together. You will need pieces of pressure treated 1x3 lumber. If your greenhouse is 20 feet long you will need 60 feet of these boards. So that is 3 ft. of 1x3 lumber for every foot of length of your greenhouse. Get an extra board or two for splicing boards. You will also need 3 metal u-bracket pieces for every piece of PVC pipe for attaching the 1x3 lumber pieces to the PVC pipes.




Attach the lumber approximately 24 inches from the ground on each side of the greenhouse and another at the top.
