- HOW IT WORKS: The Cannabinology STS Spray Kit contains a proprietary aqueous formula of Silver Thiosulfate (STS). When applied to plants at, Silver Thiosulfate (STS) blocks the action of ethylene, the “female” hormone in plants. Blocking ethylene forces a female plant to produce male-type flowers, pollen sacks, and pollen. Since this pollen was made by a female, the pollen can be used to pollinate a non-treated female plant (or branch) creating feminized seeds which will be 100% female.
- HOW TO USE: Whether you’re just starting your breeding journey or are a seasoned breeder Cannabinology STS Spray Kits make it easy to make feminized seeds. Add water then a small amount of soap to the STS Spray bottle. Apply STS Spray to a female plant starting on day 1 of flower; repeat every 5 days until day 20 – 30. Pollinate a non-treated female plant. Grow the female plant until seeds are mature. For important tips on using Cannabinology STS Kits, see the included instructions.
- BENEFITS: Cannabinology STS Spray Kits provide new and seasoned breeders the easiest method of reversing female plants and producing feminized seeds. You can easily save your favorite phenotypes, produce new feminized crosses, and even flush out rare genotypic or phenotypic traits.
