How to use our Genie STS feminizing liquid.
Using Genie STS is easy and you only need to apply our solution three times to turn your female plants into a male.
The “male” plants need to start their flowering cycle directly after the first treatment and the females about 10 days later, depending on the strains used.
The following schedule will give you the exact procedure that we follow here at Seedism HQ.
Day 1
- Mix bottle 1, containing 75 ML Genie STS, with 425 ML of distilled water and shake for at least 60 seconds
- Spray your plants until they are soaking wet, start with the undersides of the leafs at the bottom and work your way up to the top of the plants and then spray the top of the leafs and all the branches.
- Place your just treated plants directly in a 24 hour dark cycle to kick-start their flowering cycle.
- Do not start flowering your female plants until day 8-12.
Fast flowering plants can start faster then slower flowering strains.
Day 5
- Mix the second bottle, containing 75 ML Genie STS, with 425 ML of distilled water and shake for at least 60 seconds
- Spray your plants until they are soaking wet, start with the undersides of the leafs at the bottom and work your way up to the top of the plants and then spray the top of the leafs and all the branches.
- Place your just treated plants directly in the dark cycle to start their flowering cycle.
Day 10
- Mix the 3rd bottle, containing 75 ML Genie STS, with 425 ML of distilled water and shake for at least 60 seconds
- Spray your plants until they are soaking wet once again.
- Place your plants directly in the dark cycle after treating them with our feminizing liquid.
- Make sure to start flowering the female plants around this time.
Day 28
- Start watering your STS treated plants less then normal and give them a “starvation” regime, this will trigger an increased pollen production.
Day 35
You “male” plants should have well developed clusters of flowers and they could start opening any moment.
You should be able to pollinate your females in 7-10 more days.
Day 42
Your females have been flowering for 32 days and you should be able to start pollinating any moment.
Day 77-85
Your females should be ready for harvest at any time now, check a few of the seeds every now and then to establish their maturity.
It is advised to “cure” your seeds for a few weeks in a dry and dark room/area.
