Male pollen

I cut off some male pollen how do I preserve it? should I put it in the freezer?

I would suggest if you have a male plant to pick off the flowers and dispose of them...they will grow back after being picked and the plant can be kept in veg until the pollen is needed. Picking off pollen sacks individually can be very time consuming. Also male plants can be cloned to help keep them around.

Put it in an airtight copntainer and freeze it if you want to keep it a little longer but from what I've read a month is about the lifespan.
