When making your own seeds you can combine your favorite strains, resulting in a plant that you’ve created yourself that is 100% feminized. When you combine two strains, you’ll get various phenotypes with varying qualities and structures. It’s important that you use regular seeds to do this, as feminized ones are much too weak and might have issues such as stress and end up becoming hermaphrodites.
You generally want to use the pollen as fresh as possible on a plant that is fully ready to take it on, or else it simply might not work – it’s kind of like people, in that sense. Certain things need to be just right. To harvest large amounts of high quality seeds, you’re probably better off doing a few tests in order to find out when the right moment is. You can do this by testing it out on the same strain before going big.
STS is used by spraying it on your plants leaves, making sure that it’s entirely covered and dripping. We recommend taking the plant away from your growing area before beginning the process, or the mixture might end up getting on your other plants too. You’ll need to begin applying it 4 or 5 days after flipping the lights, right before your lights go off. This allows you to spray the plant without worrying about the light burning your plants. After 10 days, you need to respray your plants, using the same process, covering the plant in the mixture and letting it soak in in the dark.
In order to stabilize the genes in your resulting plants, you’ll need to select the phenotypes you like the most, meaning that you’ll need to grow quite a lot of the seeds that you get from your feminized plant. Then, take a clone from each plant and set them to flower in order to study their characteristics. Once you’re done, you’ll need to pick two mother plants, revert them and cross them with each other to get a more balanced version. This process is repeated as many times as necessary in order to create a balanced strain that has the characteristics you’re looking for.
In order to efficiently pollinate select plants, we recommend having two completely separate grow rooms or areas to work in. One should be for the plants that you’re planning on switching to male in order to obtain female polen; the other should be specifically for the plants that you plan on pollinating once you’ve reverted the other ones.
The sprayed plant will begin growing male flowers with pollen with can then be used to pollinate whichever plant you want, causing seeds to appear that have absolutely no male genes in them. You can use the pollinated plant in order to make extracts from its resin; the amount of seeds it’ll produce will render it pretty much useless in as far as smokeable flowers. The plant that you’ve applied the STS to will need to be thrown away, as it’s much too toxic to do anything with and if you consume any of it, even its resin, you could run in to some health issues.
You’ll need protective material such as gloves, safety glasses and a face mask; STS can be quite toxic when inhaled and it can leave large burns on the skin. Make sure you don’t use any metallic objects when making STS – everything should be plastic, as metal can alter the composition and reduce efficiency.
Making your own STS only takes about 15 to 20 minutes and you’ll need two ingredients: Sodium Thiosulfate and Silver Nitrate, both of which can easily be found in any pharmacy and on our webstore. Sodium Thiosulfate is a neutral chemical salt that’s used to reduce side-effects in some cancer treatments and can easily be bought without a prescription.
The result is 50ml of pure Silver Thiosulfate, much too potent to use on your plants, so you’ll need to water it down a bit. Add your Silver Thiosulfate to 400ml of distilled water, so you’ll have around 450ml of STS. Make sure to shake quite a lot until it’s completely mixed. It’s still much too concentrated to apply straight onto your plants; take 100ml of the mixture you just made and add it to 400ml mor of distilled water. You now have 500ml of a usable STS mixture that’s ready to be used on your plants.
