My main interest is to provide available sources of materials that are difficult to keep in solution. In practice, the toughest of these is soluble calcium. I currently use either
Botanicare's
Cal-Mag, or calcium nitrate, a dry nutrient salt. Of course, neither of these options is organic.
I want to find an organic source of water soluble calcium for two reasons; one, to make
triacontanol tea with all natural ingredients, and two, because I'm accumulating nutrients needed for and compatible with an aquaponics environment...
Here, fishy, fishy...
