Very interesting reading!
I use distilled water, one gallon plus 12 tablespoons of Hyd peroxide. I almost always get 100% germination, keeping them in the fridge in their baggies until they are large enough to plant. It normally takes about 3 weeks for them to sprout.
I'm curious about the seed viability thing. Since I have a hard time throwing things away, I think I still have some seeds from 2009.
I'm gonna try sprouting them and see what happens!
