keep in cold environment, or simply in a cool, dry and dark place, but the seeds should be dried enough 6 to 7 days in sunlight so i won't get damaged.
even seeds can be kept for 5 years, but maintain the temperature of 40 to 50 degree Fahrenheit.
I keep mine in a mason jar, in the fridge. I put the jar in a brown paper bag to eliminate light. I add rice or dessicant(sp?) pack, to help rid the jar of moisture. Just germed some Blockhead beans that were 5-6 years old.:party0044:
