I tried using MG potting soil mix. It has 6mo time release ferts. It killed the seedlings(at least I think it was the ferts). Anyway, I see some little jell-cap like spheres in the soil mix, which I think is the time release mechanism for the ferts. If I carefully sift through the soil and take all of them out, shouldn't that get rid of the time release BS? Has anyone been desperate enough to try this, if so did it work? I'm disabled so I have a hard time getting to the store, or I would just get some other soil.
