Quality Store-Bought Colloidal Silver?

[trichomechaser]

I'm hoping to do some breeding later this year, using colloidal silver to reverse female autoflowers. Has anyone here had success with store bought colloidal silver? Finding the right PPM without the addition of other elements into the mixture seems quite tough. I'm aware of the DIY method using silver rods and batteries, but would just like to avoid that effort if the same quality can be found in the stores. Definitely needs to be above 20ppm, but hoping for 30+.

I have never tried with colloidal silver, however I can tell you the stuff we get at the store for personal use is only 5ppm. Back in the 'ol days some people used aspirin sprayed onto a flower for a week or two, not sure about the dosage tho.

Does it have to be colloidal silver? I have had success inducing male flowers onto females by disrupting light cycles. Very easy method.
