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.
