How to Apply STS for Feminized Cannabis Seeds
Master the art of STS application with our comprehensive step-by-step guide featuring CannaCoat sticky film technology for maximum effectiveness.
Total Time
3 weeks from first application to pollen collection
Apply STS when plants are 4-6 weeks into vegetative growth, just as pre-flowers begin to form. This timing ensures maximum effectiveness because the plant's hormonal system is most receptive to sex reversal at this stage.
Pro Tip
Look for small pre-flower formations at the nodes. These indicate the plant is ready for STS treatment.
Gather all necessary equipment before beginning. You'll need:
- Mary J Apothecary STS Spray with CannaCoat technology
- Clean spray applicator (if not using pre-mixed spray)
- Protective nitrile gloves
- Safety goggles
- Well-ventilated workspace
Spray STS solution evenly onto plant leaves and nodes until surfaces are thoroughly coated but not dripping. Focus on:
- All leaf surfaces (top and bottom)
- Node sites where flowers will develop
- Growing tips and new growth areas
CannaCoat™ Sticky Film Technology
Unlike DIY solutions that drip off plants, our proprietary sticky film literally adheres to nodes, stems, and leaves for maximum absorption. This revolutionary technology increases transfer rates by up to 40% compared to traditional solutions, delivering 99%+ feminization success rates. Heat-resistant and UV-stable formula maintains full potency for 6 months.
Apply the second STS treatment 7-10 days after the first application. This second application ensures complete sex reversal and optimal pollen production.
Use the same application technique as the first treatment, ensuring thorough coverage of all plant surfaces.
Timing is critical: Don't skip the second application. It reinforces the sex reversal signal and maximizes pollen sac development.
Over the next 2-3 weeks, watch for male flowers (pollen sacs) to develop at the nodes. Signs of successful treatment include:
- Small green clusters forming at nodes
- Pollen sacs developing instead of pistils
- Sacs beginning to swell and mature
When pollen sacs open, collect the pollen and use it to pollinate female plants of the same strain to produce feminized seeds.
