So I found this old bag of black sand around my house and read how sand can be used to improve drainage for plants. Mixed it with some peat, compost, bat and seabird guano. But after doing some research Iām not sure if itās the safe kind to grow plants for consumption. I tried finding info about it but thereās not much written on the bag and most of the words are scratched. I think it says āBasalt Sandāā¦ Can anyone tell me if itās toxic? I already potted a few seedlings with the mix, but if the risk is too big Iāll pull them. I just wanna make sure the plants grown in it will be safe to smoke/consume.
