From a fellow grower: Can I use this colloidal silver?
I was told my 350ppm was too much, maybe with dilution.
I would dilute it. 20 to 30 PPM is plenty to get the job done.
It has been known to cure almost any human ailment but also turn u into a blue person excellent treatment.
Silver thiosulfate is probably a better alternative if looking to create feminized pollen.
