Be very careful, that pollen can linger on branches and leaf material only to get blown onto your photo periods later on. Try rinsing her, allow pollen to hit her twice a week apart if possible, assures lots of good seeds. A week after 2nd pollen drop, give her a shake and then a good rinsing. this will get rid of any loose pollen laying on the plant so it doesn't get blown onto your photo periods later.
Also, after the 2nd pollen drop... mark your calendar. 6wks min to produce good viable seed stock. soon after this you'll notice some of the calyx's opening and seeds trying to fall out, harvest now. Dry up good and seeds will fall right out with a slight rubbing against a small screen.. plus make you some nice kief.
good luck bro
