Great info TSK. You're the 3rd person to recommend STS over CS. Since I don't know how to easily obtain STS, and I can purchase 20 ug CS at any health food store that's what I use. I spritz the target plant 3 times daily so I'm assuming that's equivalent to 60 ug applied once daily.
The first time I tried the process, the plant did turn black in places and showed severe stress. In my particular case, I thought this was caused by impurities and contaminants left in the sprayer I was using. The second time, documented in this thread, the target plant showed no visible blackening and the plant exhibited very little stress and th e plant produced small amounts of viable pollen.
Below is my new target female. She was started from seed under a 12/12 light regime and expressed her female pistils at about 3 weeks from germination. I waited till she showed sex before starting CS treatment. I'm going to give her 14 days of spritzing and then discontinue the treatments and see what happens.

I really like TSK's suggestion of putting the mature (semi-mature) pollen sacs into a jar to allow for further ripening. I'll definitely try this. As a hobby grower, I don't need tons of pollen. Just enough to pollinate a few select buds. I ended up with roughly 100 female seeds from the last pollination. For me, that's perfect. It looks like TSK has the solution for scaling up the process. Those interested in commercial quantities should take heed. Again, for me, the last thing I want is to seed up an entire plant or heaven forbid, the entire crop.
Just as a side note, below is a regular male BB. I just wanted to show my current pollen collection technique. Again, this male was started 12/12 from seed and moved to isolation for pollen collection. I just tilt the whole pot and place a ceramic tile under the terminal bud. I shake the plant once a day, let the pollen accumulate for several days and then remove and replace the ceramic tile with a clean one. After removing the ceramic tile, I set it aside and let the pollen dry for a day or so. Then I just scrape the pollen into a pile with a razor blade and place it in a little paper envelope and store it in the freezer till I need it. This process can be repeated several times. I'm going to use this identical process for the reversed female with the exception that instead of discarding the male flowers, I'm going to put them in a jar or vial to see if I can increase the amount of pollen I collect.
