Why did you switch from single vinyl rails to double? How is the horizontal part of your steel trellis connected to the sides? How did you do your irrigation? Thanks for all the great info and pictures!
I switched from single to double so I could grow potaotes and carrots, and because my gardens are surrounded by gravel. It gets REALLY HOT in the summer, and I felt like the heat was stunting the growth of my plants. The extra soil has really helped retain moisture and protect the roots from overheating.
I purchased the trellis at http://www.squarefootgardening.com. It came with all the pieces to assemble it.
I have separate valves for each set of gardens (east and west). It goes from there to a pressure reducer/filter, then to PVC or funny pipe. Then I used 1/4′ drip pipe with emitters built in. I arranged these every 6″ so I get really good coverage.
How’s it going? Would love to see updated photos of your SFG!
I love the new 12 inch supports. They look beautiful! I remember you said you had problems with your tomatoes. Have you tried putting them in a different box. I’ve heard it takes a few years to clear the virus – including your supports. I can’t wait to see your garden grow this year!
