I have read recently the procedure for growing Psychotria outlined by ringworm a member here. He looked as if he had great success in his endeavors. However he never said how his mix was made. Did he custom make it or was it a store brand? I looked for pine bark soils online and you can't really find a brand labeled as such. I noticed that orchid soil appears pine bark like. Maybe that's what he meant but I don't know. Thanks for any help.
