Have any of the DGC tried soil blocks? Basically you compact soil to form a block that supports itself and you grow directly in that. I have scene a lot of them in regular gardening forums, but nothing with people trying cannabis in them. I was too late for my next run, but am starting some veggies in them. I diy’d my own block maker with some pvc, but they have some nice store bought ones. https://smallfarms.cornell.edu/2021/04/soil-blocking-in-five-easy-steps/
