Hey @HashFart great question and although I'm not experienced ill tell you what I plan to do and maybe others can tell us the right way haha.
I have my male in a separate tent, actually in the garage where the ladies tents are in the house. I plan to collect the pollen out in the garage and then I will carefully pollinate each branch and label the branch. I'm debating if I should pull each female out of the tent when I pollinate but I wonderbif me moving them back would cause more pollen to fly around. Other things to think about is turning off fans and wearing different clothes and washing hands etc when going from one tent to the next.
I remember seing a video of guy that just mist himself down with a spray bottle
with water apparently stops pollen from spreading
