Our first order of several of these were put in a new greenhouse, and they are very easy to manage and are producing well. We started with a stick/log hugle-cutlure base, added our own bio-char along with soil and compost. The next "set" will go outside and we've planted some of our garlic in them this fall, so we'll see how that works. After 12+ years of constant upkeep of our scrounged wood raised beds, this is soooo much easier!
