By the way here is an example of what i did the last time:

Other option would be to make something where the pollen can fall from aluminium foil and have it hanging from the plant.
The first pic is when i took it out of the closet and shortly after got a 150w led i could use for it. If you keep it under too low light, flowering will slow down and if only some part gets good enough light(spot light) only that spot will develop properly, so you dont need to get tons of pollen all over the plant. You can also cut off stems that are not worth harvesting, but dont be too rough on it or it might need time to recover. Which especially under low light is not good.
Here is a freakshow i put under 9w led after it showed first flowers and it was enough light to harvest enough, the photo was taken after i had already been able to put a little in two plants and also take a bit on store. As you can see most of everything else than the main cola has dried off and did not make pollen properly. This is because the led was only lighting the top and rest was uner normal room lights. It did make less pollen than with 150w and while 9w china led seems barely good enough, i would recommend a bit higher power, but 150w is already an overkill for sure if you just want to make a little pollen.

It doesent matter if the male stays small like this. If it makes viable pollen, its viable and it doesent make difference if its grown big and under big lights or flowered like this. Its genes are what matters
