Are you having germ problems as well? @DougDawson was having them as well…this is my take:. DON’T USE PAPER TOWELS, why you ask?
Have you noticed when you germ beans in a small amount of water the water becomes cloudy? If left in this cloudy water, germ rates are significantly negatively effected. This is why I use at least 6 ounces of water to pop seeds, or it must be changed periodically.
How much water is in a paper towel?? A quarter of an ounce??? This isn’t enough water to keep the area clean for proper germination, I’d say.
