Hey @Cormoran i use the COM Stonington blend almost exclusively, it’s great stuff. Comes with a pre charge of nutrients, in smaller containers though you’ll need to supplement, but the claim is that in a larger container it’s enough for a full cycle plant. In reality it’s not quite enough, I grew my outdoors in 20gal fabric pots with just the stonington blend and did pretty well but supplemented with a couple teas and a couple too dresses, probably could do more if you push the nutrients harder. Either way I’d totally recommend COM stuff, love their dry amendments too!
