I am trying to grow balls on one of my females. It's a White Russian, and I do want some of those much sought after seeds. I "built" a a colloidal silver generator. My design utilizes a full gallon of distilled water. For the top I use a two hole laboratory stopper. The silver electrodes fit through the holes thus being insulated from each other. They are simply held in place by the alligator clips. To be on the safe side I also purchased some certified colloidal silver from Amazon. With any luck I will soon have some balls. I am using one of my ubiquitous obsolete AC adapters for the power supply. 12 VDC 300 milliampere. Thanks to Nebula, and PhenoMenal https://www.icmag.com/ic/showthread....lver+generator for the instructions.
