How to make slow release root tabs? I dont know.
I have been trying to make my own root tab using dry ferts, I was just wondering if anyone has any idea on how to do this. My idea was to use natural clay and knead fertilizer into it, then form into tabs and let them harden. I was looking for a slow release so I could load them up with ferts. My experiment, once put in water completely dissolves into powder form in about 20 minutes, I suppose this would release all of the fertilizer. I donít think firing them would work because then they might never dissolve. maybe a hybred of clay and cement or plaster, I dont know. If I could make it last not more or less than a month I would be happy.
