STS, Silver Thiosulfate. Kits to make Feminized Seeds + GA3

Fresh ingredients! I've personally used this non stop for years now. I mix a new batch for myself once a month, and it works flawlessly. 100%I spray basically when I can, at least once a week, but not more than once every 3 days. This is a 2 part mix to make 8 ounces (236ml) of 3.4mM strength STS (Silver Thiosulfate). That's .4mM stronger than recommended by the American Society for Horticultural Sciences- search: "Foliar Sprays of Silver Thiosulfate Produce Male Flowers on Female Hemp Plants" This is made from very high quality, Reagent Grade, Sodium Thiosulfate Anhydrous, Silver Nitrate, and only distilled water.It can be stored in the separate containers, until you are ready to use.Once they are mixed, the solution should be used within 30 days.It takes approximately 21 days to start getting pollen.I like to spray every 3 to 5 days, but once a week has never failed me either. Caution: Be sure to isolate your plant when spraying. This will cause plants to hermy if accidentally spraye
