Saw this on last trip nw. Building an out door growing bed, use a backhoe or excavator, dig six to eight foot deep trench. Full with old logs half full, gather forest til(top three inches of forest floor) add to trench, top with mixture of rice hulls and compost. Plant a large female, and cage, cages were four cattle panels wired together to form cube 5'x5'x12'tall, was told as plant grows to height it is supported by bamboo cross supports placed horizontally. This way you can climb the cage to service the plant. Plants were 8' on the fourth, and just starting to bud. Sorry no pics, not that crazy, these guys are serious.
