Thanx for the tips I’m gonna give it whirl - worst thing happens I end up a tent full of seeds , been there done that . LolNot much, yet. I'd definitely get that dude in isolation, he'll be dumping soon. With the size of those sacks it might not be a small amount either. You'll definitely know.
All I do is catch the pollen on some folded paper and put it in a seed vial with a bunch of silica beads to absorb moisture. Well, after turning all of the fans off. When they get turned back on, the air gets directed away from the flower room. Yeah it'll travel a long distance in the wild, but it's not going to go against negative air pressure and around multiple corners indoors if the flow's right.
The pollen vials get stored in another airtight container with more silica beads and last for weeks to months. I've still got some Super Lemon Moon pollen from the dude's original flowering that seems as viable as it did on day one.
