male pollen?

i have one female x thai plant that has started flowering about a week and a half ago and was wondering if there is any chance of this plant to become pollenated because this plant was sat next to a hermie that released pollen around 2 months ago and since then the female has been on its own. how long does the male pollen when dropped stay around in the grow box. frans have been blowing air into the box constanly. how do i know if this plant is producing seeds?

Pollen stays viable for a very long time. Fans or not there will be some pollen around though maybe not enough to fertilize all your flowers.
Good luck.
