I got mine at Naomi's in Portland, Or.
all natural
At the other store they carry this soil and it's made down in Southern Oregon. They are unique among soil companies in that they produce their own thermal compost and they have a modern, concrete floor, heated vermicomposting operation. This soil costs the same most of the gunk at a grow store - it's made with the same components you have available at either store.
I've used both of their humus products (compost & worm castings) and they're very solid. Not the best but definitely a good option. This is the potting soil I would recommend to new MMJ growers that are complete novices on growing anything.
Just something to consider perhaps......
