Hey guys, just an update (and +rep)
I used this method when this threead was first started with a few modifications. First major differentiation was that i baked the rice for 20 minutes to completely dry it. Then, I did the same with a few tbsp of flour.
I filled my Eppendorf PCR sample tubes (search here, this company gives out free samples) half way with flour and rice mix, and put in about 1/4 tsp of pollen and shook really well, then they all went inside 2 ziplock bags in the freezer.
I took them out last week and the pollen was completely viable, and now i have samurai jacks and a mossy mix (one of the more white rhino looking) pollinated with auto assassin pollen.
