The soil for the land area was a mixture of an organic potting soil made by a local greenhouse which is very close to Black Gold's Organic Potting Soil mixture, nursery charcoal, and ADA Aquasoil that I had left over. Basically at a ratio of 2 parts soil to one part Aquasoil to half part charcoal. I also through in some clay I had left over from other projects. The soil is still very arid and retains moisture well. By design all mist water will trickle through the soil and the soil guard mesh into the void area below and back into the sump. The sump is on a trickle pump that constantly keeps the waterline and overflows into the void areas and back through the duct work where the fans are. This also serves to keep humidity high and temperatures down.
I could work up a basic schematic how the systems works.
One thing that has amazed me is how long the manzanita has held up. I did not expect the wood to last this long under high humidity.
