Silver thiosulfate

Wow.... Good question and I haven't a clue. Is this for producing feminised seeds ?

Yes this is for feminised seeds probably should have said , I,m sure its  much the same as  using colloidal silver but I haven't done before either

@sandgroper I’m in the process now of a seed making run using STS. There are tons of guides on YouTube on how to make it. You’ll need a scale that’s can measure micro-grams or milligrams to make small batches. Remember to add the soap for a surfactant too. Once it’s made start spraying the bud sites at flip and continue to spray those bud sites once every 5 days for a total of 6 sprayings. It really doesn’t take tons to get the female to reverse. Don’t spray the leaves, just the bud sites. The females that will be receiving the pollen should be flipped 2 weeks after you begin treatment with the STS in order to have the female in a prime place to catch the pollen. Some plants make tons of pollen, some make very little or none, you won’t know till you try.

I think STS is the way to go given it takes much less in application. I have mine ready to go -- just waiting on the right grow and the right time, but am excited to make my own seeds. Keep us posted!

@monkeydo thanks for expanding this topic I was hoping to get some discussion from within the Percy crew but for you to take the initiative and actually do it is so very cool thankyou
