Q: Say 2 plants in flowering are pollinated

Okay I had 1 male in flowering waiting for it to produce pollen sacs so that I can cross with something else. But I also had 2 females in the closet that got pollinated by busted sacs. 1 female was about 2 weeks from harvest (which was last night) and the other was about 4-6 weeks from harvest (a little behind and takes longer to flower).

What I want to know is if I have other plants flowering with these 2 which just begun their cycle -- 1 is 17 days the other is 4 days. And the male is chopped already. Do I have to worry about these pollinated plants (well, 1 now which is weeks away) spreading the pollen to these fresh flowering plants? Not too sure how this works.

The only way that is going to be a problem is if they have pollen all over them.

Hmmm. I don't know how to find out if they have pollen all over them. I doubt it. I'd think the fans would have blew any extra off by now. Plus I kind of thought flowering plants had to be older to be pollinated. Not quite sure. But -18 doesn't seem like it would be a problem.

The big question is how long the pollen stays good? Does it die and become no good after a while? HMMMMMMMM
