The container, yes. IMO, it is always wise to dry or freeze your harvest for long-term storage. I keep all my seeds in 1" dia beading containers and then in the bottom back of the refrigerator to slow deterioration. Pollen, like seeds, can last for years if stored in a dark, dry atmosphere.
The following pics are from previous harvests. One learns new tricks with experience.

As of today, I have 20 of these little containers filled with seeds, and 5 4-oz GLAD containers partly filled with pollen and spent pods. Because I want to save my last 4 beading containers for the Harly seeds, I combined the unknown Sativa pollen into a GLAD container.
You can buy a set of 24 beading containers at a craft shop, like Michael's. They come in their own plastic tray, so everything stays organized. One of the handiest purchases I have made.
