Hello, my name is Brooke I'm a freshman in high school. I made this project for my engineering class. It was a lot of fun making this and I love the way it turned out. I hope you enjoy!
Step 1: Gather Materials
-Two 4'' PVC pipes: Mine are cut to about 66.5'' and 59''
-Four 4'' PVC end caps
-Spray paint (I used silver)
-Wire rope (I used about 20')
-4 sets of small wire rope clamps
-8 threaded hooks
-Four carabiner clips
-9 little plants of your choice
-3'' hole drill bit
-Small drill bit for pilot holes and drainage
-Saw for cutting PVC pipe
Step 2: Cut PVC
Cut PVC pipe to length desired (again I used 66.5'' and 59')
Step 3: Drill Holes
Measure out how many holes you want for the plants. I did 5 holes each 11'' apart on the longer one and 4 holes also 11'' apart on the smaller one. These holes were made with the 3'' drill bit.
Step 4: Sand and Paint
Using sand paper, sand both PVC pipes completely; especially the rough edges made by drilling the holes. After sanding, stand the pipes and caps up so that you can spay paint them. Let dry completely before moving on to the next step.
Step 5: Attaching Hooks
Find the center between the first and second 3'' holes from both ends and mark it (this is done one both the longer and short PVC pipes). Drill small pilot holes on these marks and screw in hooks. **Make sure the hooks are centered on the top so it hangs correctly. Then, on the longer PVC pipe, find where the hooks on the bottom pipe would be. Follow the same procedure for attaching the hooks on the bottom side of the longer/top PVC pipe. Finally, attach the last two hooks to where they entire garden will hang. Be careful to make sure it is exact so it will hang straight.
Step 6: Make Wire Rope
Depending on where you want your hanging garden to be, cut the wire accordingly, leaving about 4'' of extra wire so that you can attach the wire rope clamps. Because of where mine was going to hang, I made the wire rope 6' long. Then, make the smaller wire rope for attaching the top PVC pipe to the bottom one. **Be very careful when making these wires, if you fail to make each pair exactly the same length, it will not hang straight.
Step 7: Soil
Pack the soil into the PVC pipes and put caps on all ends. You can glue these on if you wish, otherwise, hammering them down should make it tight enough.
Step 8: Final Step
Using the carabiner clips, hook the PVC pipes and wires onto the hooks. Don't forget to drill holes on the bottom of each pipe using the small drill bit. This is so the water can drain. The number of holes is up to you. Finally plant whatever plants you want and enjoy!
