Ya, I agree to use that for veggies or something in an outdoor container. Advanced nutrients have a lot of salts so I wouldn’t dump it in to the native soil. But it’s make nice for some tomatoes and peppers!
Sounds like a good idea :Dstart a container garden with it,most veggies do best at 6 to 6.8 ph as it is,potato plants dig 5.5 you can grow them in saw dust if you wanted,just dont grow any other plants in that soil,i have soil just for potatoes and grow them in contractor bags from home depot,just line um up on the fence edge,grow sweet potatoes same way,hell ya reuse that good stuff and be rewarded by a full belly
LolLol, in one medical grow I worked on we were pretty much building a ski-hill in the back yard out of promix. The pile after a few years was about 50' round and about 25' high. No kidding. To the point that we actually built a cleated wooden ramp up it so we could empty the buckets over the top.
This is what I do...then some goes into the composting worm bin the next year to become worm castings. I always use fresh coco/potting mix for my cannabis to avoid unwelcome soil issues. Not sure if that is necessary, just don’t like taking chances.I turn it into a compost pile.
Adding your food scraps, any plant scraps, leaves, stems, roots & organic matter for breakdown over time.
Sprinkle some microbes into the mixture every now again to keep it digesting along with some moisture & mixture every so often.
Eventually you will have nice fertile soil for reuse.
