The best Method from all of the extensive research I have done...Have a sealed, air tight container...centrifuge tubes on ebay are great..test tubes, or pill bottles..
put your seeds in with a bunch of rice to act as a desiccant..moisture stabilizer...key is to top up the container with rice so that the vacant air space doesn't leach moisture from the seeds...If you intend to use them in the next year to 18 months...pop the containers in a second air tight container..ziplock,sealed jar or something then in fridge or MrToadcool and space in basement...For longer term storage freeze them...perhaps use some in freezer some in fridge as a precaution if you have technical issues...
For pollen..add approx 10x amount of baking flour to pollen..mix and store in gel caps that you can buy at healthfood stores..again store gelcaps in a secondary sealed vessel to keep dry..pop in freezer.When using..remove from freezer and let thaw for 8-12 hrs before using
