Here is my hybrid RGGS. 10 gallon root pouches with a growing mix of 3:2:1 PromixBX : Micro Bark : Perlite. Included amendments per container are 1.5 cups dolomite lime, .5 cup Epsoma starter, 1.5 cups Tomatotone in a perimeter ring near the surface and some home grown worm castings. I also free-styled a wee bit with my 6 mil. black plastic covers. Seems to be wicking nicely - maybe a little to much wicking, as the bottom quarter of the root pouch seems wet to the touch. The pic is a few weeks old, everything is growing great. Next comes a trellis system! When I get back from vacation....
