Wow, your garden looks like a science project! Great job... Did you purchase the raised beds or is that a design of yours?? Looks great.
Thanks! LOL, it was kind of a science project. I wanted to get the most production from a limited area. I had an eight tier 2 foot by 100 foot terraced garden prior to putting in the greenhouse (had to tear out the terraces for space). Learned my mistakes, redesigned and put the new project on the schedule. QE1 and QE2 were the triggers that forced me to move the work up on the schedule.
I was going to build my own boxes out of wood, but found the maintenance down the road would be a headache. We have a large front porch with vinyl railing. The railing has held up perfect for eleven years. Did some searching and found raised vinyl boxes at
Master Gardening. Expensive, but the best price I could find with shipping included.
The 3/4" PVC piping for the grid and irrigation I mass produced during two evenings. Drilling 2 holes in each section was the most work. Only needed to cement the first couple sections together. The remaining stay together because of the 48 "leaks" in each grid. Works great for drip irrigation and feeding. They can be torn down and stored in rubbermaid containers during the winter. The ends, cross Ts, Ts and elbows I got from
US Plastics.
I have vinyl arbors in the garage to put the grapes back up and will be using 1/2 PVC pipe and fittings for the vertical gardens. Haven't gotten to cutting up and slipping it together.
Check out square foot gardening on Google. There are great sources of information, books and pictures.
