I've only done CS, but on several strains. Even though every treated plant produced copious balls, none of them produced anything like the pollen normal male plants do. Even when left to mature well, they only dropped a tiny bit if any visible pollen on their own. For the last round I did, I waited until I could see pollen drop when I manually opened the balls. Once I reached that stage, I snipped the individual flowers and put them into a mason jar with silica gel dessicant in it (the gel was in a small cloth bag hanging from the top of the jar, the flowers did not contact it directly), and after a few days of drying, collected pollen by agitating the pile of flowers in a metal coffee filter sitting over a collection jar. I still have a supply of 24C pollen from that collection after seeding branches on three seed mother plants. I got hundreds of seeds from each of the pollenated plants - it doesn't take much.
During the last reversal of 24C and Fugue State, I used a new (for me) way of pollenating. It worked a treat, and will now be my go to.
I made a cloth bag big enough to contain the target branch to be pollenated, and attached a cord to it so it could be supported from above once zip tied around the base of the target branch. Before putting in on the target plant, I moistened it so that any pollen landing on the bag itself would be killed, and I sprayed down the plant other than the bagged branch to kill any stray pollen that managed to get loose. I applied pollen into the bag and onto the target branch by using a syringe with a needle to blow pollen into the bag. I put bit of dehydrated rice with pollen into the syringe gave it a shake, inserted the needle to the inside of the bag, and vigorously pumped the plunger back and forth so that incoming air would stir up pollen in the syringe, and the next stroke would blast it into the air inside the bag. I applied through several spots on the bag. I then left the bag in place for several hours to allow pollen to do the deed before removing the bag very gently and giving the whole plant another misting to kill any pollen loose on the leaves of the target branch. By doing the job this way, I ended up with hundreds of seeds on each target branch, and so far none from any other plant branch in the 'drobe. My plants were in big soil pots, so all this was done in the drobe with the other plants present, and still no stray seeds, at least none that I have run into yet.
Anyway test peeps, good luck with the rest of the test, I hope it goes well for all of you.
