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 I’m not sure if it’s the safe kind to grow plants for consumption. I tried finding info about it but there’s not much written on the bag and most of the words are scratched. I think it says “Basalt Sand”… Can anyone tell me if it’s toxic? I already potted a few seedlings with the mix, but if the risk is too big I’ll pull them. I just wanna make sure the plants grown in it will be safe to smoke/consume.
