Rex Grigg Dry Fert Alternative
I bought a lot of ferts from Rex, years ago, and have been using them ever since. I'm finally about to run out.
Does anyone know of another source of good clean dry ferts, like he used to sell? I found some dry ferts from a random seller, specified for planted aquariums, but they are basic hardware store grade ferts.. chunky, smelly, brown. Rex's were nice pure white powders.
Thanks for any advice.
