Make feminized marijuana seeds: how to store silver

A question from a fellow grower:

I have bin having problem with the colloidal silver it keeps turning brown. How can I stop this. I have bin storing it in my draw in bottles. What is the best way to store it.

I would advise that you do a web search, and read up on the process of using and storing this product.

I have the same problem, and my colloidal silver turns brown! Is it oxidized? Can I use it?
