I'm a Newbie to MJ growing, but in my experiance with seeds it matters how it was stored if its going to germinate or not. The plants I'm growing right now all germinated with the papertowl method, and they were stored for over a year in wrapped celephane plastic. Their doing fine.
-- AND on a side note. I'm also growing some tomato plants that I had stored for 12 years in an airtight container, and pretty much 80% of the tom seeds germinated.
