Make 1000's of Your Own Female Seeds!

 

Silver Thiosulfate (STS) is used by professional breeders. STS forces your female cannabis plant to produce only female pollen by inhibiting the production of ethylene, and will pollinate itself and other plants in the local vicinity. The pollen can also be saved, dried, and frozen for future use.

 

STS can be stored in a cool dark place and will remain viable for 1 year.

 

Usage

  1. Wait for female flower to begin.
  2. Spray flower and nodes lightly Once.
  3. Wait 2 weeks and spray lightly once more.

That's it!


Female pollen sacs will emerge 3 weeks after the first spraying. Expect female seeds to mature in 6-8 weeks.

 

Dry your pollen and save it in your freezer to pollinate your future females to make Your Own Hybrid Crosses!
