Well, everything says it's the safest fertilizer out there, and you can't really overdose. So I took a clone and potted in a mixture I made from peat moss, perlite, and worm castings. A pretty significant portion of it was worm castings. I also fed various houseplants and some lowryders a tea made from the castings to see what happens. Castings are supposed to work wonders, we'll see. At the price I paid for it, it's almost impossible to waste them, cause they were so cheap.
