Good or bad soil amendment? I’m from the anthracite region so fly ash is plentyful to say the least, a lot of people add it to their vegetable beds that Ik and have no health issues. There’s mixed opinions on the level of heavy metals in it, and we have some of the purest anthracite in the area so the levels of our coal is pretty low. Just curious if anyone’s done/ heard of this with cannabis and the results from it
