Hi Vespertino,
I'm experimenting with a pipe RGGS for the first time this season. I can't speak from experience but, I'll share my plan thus far and maybe we can bounce some ideas/experiences off each other. I bought 10 gal. grey Root Pouches, 3 inch net pots, a float valve, pipe etc. I built some supports for the pipe and plan to use a cattle panel as trellis.
The grey root pouches seem surprisingly sturdy. Who knows how well they will hold up to heat and UV? I cut circles out of the bottom and installed the net cups and weed control fabric a' la Larry Hall. I got a nice fit, seems sturdy.
Now I'm trying to figure out what planting mix to use. My first thought is to use the same mix I use for my Earthtainers, but I wonder if that mix is appropriate for the pouches. Any ideas?
