I took my male i used to breed and stuck it outside. I dont grow outside. Anyway, once it gave pollen i collected as much as i could into an envelope. I immediately froze the pollen. Obviously immediately wash those clothes and change before ever entering your flowering room. Then, when you are ready to breed(fresh pollen is best), you should isolate a lower branch of whatever you want to breed with. Then, what i did, was made little paperbag containers i added pollen to. I stapled three sides shut with an opening for the lower branch to be inserted. I bred to three females. Once you insert the branch into your little packet/bag of pollen, use scotch tape to seal the bottom part around the stem that is inside the bag. Flick it around a bit so the pollen coats everything inside. Then, i immediately covered those three branches with the bag on top with a plastic bag. After that i hit everything in the room with plain water to make sure nothing got accidentally pollinated. After everything dries take off the plastic bag but leave the pollen filled paper container on the bud for a few days. Then you can take it off and hit everything with water again. I got a ton of great seeds and little to no accidental pollination. Seeds take 5ish weeks to develop so i suggest hitting the lower branches with the pollen around 2-3 weeks into flower so they have a good amount of pistils to recieve the pollen. Anyway, thats how i did it.
