how long can i keep pollen at room temp? and still use?

hi all. i keep pollen in my basement after i collect it. its on the stem with pistals

removed. now how long is the pollen good for? a week yes?. and i have a dehumidifier on in the basement so it helps dry the pollen. will this hurt the pollen over a wthanks pat.eek?. advice would really help!!!

I used to say a week, now I am only confident for about 4 days when not refrigerated (kept in my garage). In a refrigerator, I would expect about a week to 2 weeks. For times longer than that, I would use a freezer.

You also could try storing your pollen in organic solvents to increase its storage time, see:
