Description
Sodium Thiosulphate is a product that’s generally used in the cannabis industry in order to obtain male pollen from female cannabis plants to later create female seeds- In order to use this product safely you will need to have a certain amount of knowledge when it comes to chemistry.
In order to obtain feminized seeds from your plants, you need to make a very specific mixture between two specific products; sodium Thiosulphate and silver nitrate which, when combined, make silver Thiosulphate. This is a product used by geneticists all over the world to revert female plants to male plants in order to produce male flowers. They then take the female pollen from that plant and use it to make purely female seeds.
Handling and using this product should only be done if you are following all necessary safety measures. We highly recommend thoroughly investigating this process and finding out the exact safety measures needed to be taken before handling this product, as well as wearing protective gear on your hands, eyes and mouth.
How to use Silver Nitrate and Sodium Thiosulphate Step by Step:
- You will need cups and plastic spoons. Never use metallic cutlery.
- In a plastic cup you will add 20 ml of distilled water and 0.35 g of Silver Nitrate and start diluting slowly.
- In another cup, 30 ml of distilled water and 1.3 g of Sodium Thiosulphate, stiring both slowly.

- You will dilute your 50 ml mix with 400 ml of distilled water, having a total solution of 450 ml. Then shake with precaution until you can see clear homogeneity in the mix.
- The last step, is to separate 100 ml of your final solution and add 400 ml more of distilled water to further dilute it, having ready 500 ml to use on your grow.

Man, this is amazing for anyone making their own feminized seeds! For the STS solution, it's pretty much essential, you know? The plants really appreciate it. I've used others before, but the purity of this one... top quality! Really looking forward to seeing the final results this time.

In pharmacies silver nitrate (Argenpal) costs less than 5€, and the same for the 250 grams of sodium thiosulfate. The prices on this site seem a bit inflated.
Translated from Spanish
En farmacias el nitrato de plata (argenpal) vale menos de 5€, y lo mismo para los 250 gramos de tiosulfato de sodio. Los precios de esta web parecen un poco inflados.
