Great Beans and Rice is best stored in a cool location. We suggest a freezer, but a refrigerator works well too. If you plan on storing it for more than 3 months, or you purchase it during a warm season; you should use one of those cool locations. the Rice in the mix which is pleasing to a particular pest - the Indian Meal Moth, which can appear out of nowhere when conditions are right (hot). These are organic seeds after all, so there is no other way to keep your seeds absolutely safe from them, except to freeze them. Consider yourself slightly more educated =:-}
Black Beans and Pintos are rarely prolific sprouters. They are intended as soup beans by farmers and seed brokers, and though we look for the best sprouters, always testing several lots every crop year, we are willing to accept as low a germination rate as 50%. As long as they have no hard seed they will cook just fine.
So, do not grow beyond the point where the beans that are sprouted have 1/4 - 1/2 inch tails - those that are not sprouted will either never sprout or will take too long. If you keep growing you will over-grow the sprouted beans which will be an unpleasant experience. Trust us, we know.
Not all of these seeds will sprout in the same period of time. They are close enough to mix together though, so we did. You Don't have to wait for all of them to actually pop a root. Something you Must Know: Once a seed has soaked up its fill of water, it is alive, and now super-nutritious - and - they now have no enzyme inhibitors (a very good thing indeed) so they'll digest themselves and nourish you. Growing a root/sprout is a matter of preference only - it is already a nutritional dynamo.
