When grass seed is produced by a mature plant, the seed has a lightweight, open, outer cover known as the hull. This part of the seed is not necessary for germination and is often removed mechanically during seed processing. Hulled seed has had this coating removed and will contain the highest number of seeds by weight or by volume when compared to unhulled seed that has the useless material on it. This is mostly a concern when seeding bermudagrass.
