Like many, I still pop seeds with damp paper towels. However, on a few occasions I’ve noticed the little root hairs can migrate through the plys of the paper towel; making it a challenge to remove them without damaging the fragile little roots.
I discovered these blue paper shop towels that are more woven and fabric-like. They are very durable and protective of the little babies. They are sold by Harbor Freight Tools for $2.97 but you can catch them on sale for less.
