Sodium Thiosulfate (Na2S2O3) is a chemical compound primarily used in cannabis cultivation as a key component of Silver Thiosulfate Solution (STS). This powerful solution acts as an ethylene inhibitor, effectively blocking the plant hormone ethylene, which is responsible for promoting female flower development. By inhibiting ethylene, STS induces female cannabis plants to produce male flowers, which in turn generate feminized pollen. This pollen carries only female (XX) chromosomes, ensuring that any seeds produced from it will be feminized.
For you, the dedicated grower, Panreac Sodium Thiosulfate offers unparalleled control over your cannabis genetics. Imagine being able to create your own feminized seeds from your most prized mother plants, ensuring consistent quality and traits in every harvest. This method is widely preferred by professional breeders due to its superior effectiveness compared to alternatives like colloidal silver, requiring fewer applications and yielding more reliable results. It's an indispensable tool for genetic preservation, strain development, and ensuring a crop composed entirely of cannabinoid-rich female plants.
To harness the power of Sodium Thiosulfate, you'll need to prepare an STS solution. This product, Panreac Sodium Thiosulfate 500g, serves as "Solution B" in the two-part STS preparation process. You'll typically mix 2.5 grams of anhydrous sodium thiosulfate (or 3.9g of pentahydrate) with 500ml of distilled water to create Solution B. This is then combined with "Solution A" (silver nitrate and distilled water) just before application, and further diluted to create the final sprayable STS solution. For optimal results, spray the diluted STS solution onto the nodes and bud sites of your female plants until runoff, ideally in low light conditions or just before the dark cycle, as STS is light-sensitive. Repeat applications every 3 to 5 days until male flowers begin to form. Remember to always wear protective gear, including gloves, goggles, and a mask, and ensure treated plants are not consumed.
Choosing Panreac Sodium Thiosulfate 500g means investing in a high-quality, reliable product for your cannabis fertilizers and cultivation needs. This generous 500g quantity provides ample material for numerous STS preparations, making it a cost-effective solution for both hobbyists and commercial growers. Its purity ensures consistent results, giving you the confidence to experiment with your genetics and produce top-tier marijuana seeds. With Panreac, you're not just buying a chemical; you're acquiring a tool that empowers you to achieve your breeding goals with precision and efficiency.
Is it safe to consume plants treated with STS?
No, plants that have been directly sprayed with STS solution are not fit for consumption. It is crucial to use treated plants solely for pollen production and seed creation.
How long can I store the STS solutions?
The individual stock solutions (Solution A and Solution B) can be stored separately in dark, cool conditions (preferably refrigerated) for extended periods, even years. However, once Solution A and Solution B are mixed to create the final STS solution, its effectiveness lasts for approximately one month when stored properly in a dark place.
Can I use Sodium Thiosulfate to prevent hermaphroditism?
Sodium Thiosulfate is primarily used to *induce* male flowers on female plants for feminized seed production, not to prevent hermaphroditism. Creating a stress-free environment is key to preventing unwanted hermaphrodite traits.
