I have also been curious about this.
Ive got some pollen stored that is nearly 2 years old now. When I harvested it, I made sure to dry it out for a day, cut it with flower, added some grains of rice, then separated it in to 5 individual plastic seed vials, I have 4 in the freezer and 1 left in the fridge.
I sent a vial from the freezer to a friend last year, however he waited a few days before using it, and sprayed his plants down less than 24 hours after pollination, from what he said he didnt get any seeds from it. I suspect this is due to him waiting a few days before using it.
Im just wondering what are the chances it is still viable, and would I be ok to use it immediately out of the freezer? Also what about the vial in the fridge, what are the chances that its still viable after 2 years?
