Fem-Bloom Pro
$69.99Precision STS Elixir (Silver Thiosulfate) spray is a chemical solution used in the cultivation of cannabis plants to induce the production of feminized seeds. By applying STS during the early flowering stage, it disrupts the natural sex determination process, leading female plants to produce pollen with male characteristics. When this pollen fertilizes female plants, it results in seeds that are guaranteed to be female.
