Re: [GSAS-Member] Anyone use a UV sterilizer?

[Matt Staroscik <matt@wrongcrowd.com>]

Yeah, UV probably clobbers that chelating agent. I dose micro ferts once in
a while but honestly I don't think my plants grow enough to need them.

I have found good reviews on one of the cheaper units, the "Green Killing
Machine," so I will probably get one and try it out. It never hurts to have
another tool in the toolbox.
