I concur in regard to using a bit of Colloidal Silver in a spray bottle of water for mold. I started to develop mold, added approximately 1/4 tsp. to a standard size windex spray bottle, and after one spray and a few hours time, the mold was gone! I now use it regularly as a once a day spritz along with some miracle grow in the spray bottle. (not too much, just a bit) My grass looks amazing and green, and that's under grow lights. I'll let you know how it tastes, but I'm sure it will be great.
