Buy regular seeds, find male plants. Or, mix up some STS with fairly cheap products off ebay (silver nitrate is 2usd/gram give or take, anhydroud sodium thiosulfate is 7-8usd for 113grams) Sigma-adlritch has a recipe that you have to further dilute 1:5.67 or 1:9 for a 2-3mM concentration. https://www.sigmaaldrich.com/US/en/technical-documents/protocol/cell-culture-and-cell-culture-analysis/plant-tissue-culture/silver-thiosulfate Again, that recipe results in a 20mM concentration. It needs to be diluted further to get down to 2-3mM. Don't use metal utenils as some of the ingredients are highly corrosive. It cna permanently stain stuff, too, so put something down to protect whaver surface you use. I wouldn't do the double replacement reaction different from the instructions outside of overall scale. don't try to mix it up at 2-3mM concentration. Pretty sure it's important for the reaction to effectively take place, then you can dilute. I wouldn't assume otherwise, but no gaurantee. You'll want a milligram scale if you want to reduce waste... +/-.003g error. When i mix up a "250mL" batch it's weight out soemthing as low as .085 grams of silver nitrate. Those cheap +/-.03g scales just can't do it well - up to a 37.5% error on either side of target mass. And, that still makes WAY too much for 1 small plant. With a "milligram" scale that error is 3.75% which is tolerable. Can still get onen for ~20 usd. they aren't too expensive and worth it for this.. plus if you do coke, it's a good scale for that too, bwahah. as long as a plant doesn't naturally herm out, stressing it to create pollen is okay. it's the trait of herming by itself that is to be avoided. they all have the potential to herm out. it's in their DNA automatically. so don't apply STS to some plant that pops a ton of nanners or sacs without any help and you'll be fine.

strainly has male pollen you can buy

I echo what other said. by reg seed. its a 50/50 mix. go 12/12 from seed and keep everything stupid simple. the plants will not need a transplant or anything they are only going to be a pollen donor. does not need to be big or anything can grow it out in 1-2L Feed it mircale grow and it will do just fine.

If you dont want to hunt for a male yourself. People sell male pollen on strainly. You possibly could get male clone also. Just do some research on the seller before buying anything.

Lots of seed banks sell regular seeds. Like others have said its the luck of the draw how many male seeds will be in there.

Regular seeds (seedbank) strain of choice. No guarantee sometimes regulars put out all females. Stay at it. Odds of getting males depends on how many plants your environment can handle. How you choose pollination is up to you. or, go the feminization route!

1. You can buy non-feminized seeds. Keep popping until a male appears. 2. Stress a female so badly that she hermies. (Not a good choice if you want quality pollen)

Buy regulars ( not Feminised and not Autos ), as i remember from 10 on average , you get 4 males and 6 females. There is some banks who sell pollen for huge $ , but during transportation you can get it bad, its vital not for long, sensitive to humidity and temps. I saw more bad reviews than good about such banks. Think regulars is the way. One house i should mention for NOT BUYING from - its TOP TAO SEEDS, i won some seeds from them, they were regulars ( haven't grew such for last 7 years at least ) , potency of the ones that made it - was weak, got some hermied or going midget size, so was very disappointed., but had a bit of males ;)))) could bread weak weed ;))) There are other ways too, without males or bought pollen. Some people reverse girls and make theirs own seeds. Have a look : growdiaries.com/diaries/205494-buncha-stuff-grow-journal-by-001100010010011110/week/1173942
