Several years ago, I germinated a BUNCH of seeds in H2O2 mixed in with water in baggies in the refrigerator. Worked great! The next year I tried it again and got very poor results. I have no idea why. But eventually 80% of the seeds all rotted in the second batch. Since then, I've been very reluctant to try that method again. I guess there is a fine line between germination and rotting?
