Here's a system that has been working for decades. Get a heating mat, propagation station with seed starting medium. Make sure you also have a sufficient light for seedlings before you ever touch those beans to water. Get some paper towels, a saucer, plastic wrap and a hand towel. Plug in mat, fold hand towel over mat and place in a safe place. Place saucer on hand towel. Wet paper towels, place seeds between two and three layers of paper towels and place on saucer. Cover saucer with plastic wrap but leave one end up to beath.
This will create a warm moist environment for germination.
Check every 12 hours and as soon as you see a little sprout plant it in your propagation station, root down about 1/4 to 1/2 inch. Place propogation station on mat and cover again with the plastic wrap. Remove wrap as soon as seeds sprout and put under seedling light.
