Do I need to add filler to my seed mix?

Allendan Seed adds Parboiled Rice Hulls to the majority of our inventory seed mixes as inert material to reach a 10 lbs. an acre seeding rate. Parboiled Rice Hulls are a natural and renewable plant material used in a wide variety of applications that include potting material in the greenhouse and nursery industry. Parboiled Rice Hulls are subjected to a series of heat treatments that sterilize and render any residual rice kernels or other seed non-viable.

Your Allendan seed tag will note or reference if it has Parboiled Rice Hulls in it. You can request additional Parboiled Rice Hulls be added to your seed mix with additional cost if you prefer to have a heavier lbs. per acre seeding rate. If you wish to purchase an inventory mix without Parboiled Rice Hulls, it becomes a "Custom Seed Mix" and will generally cost more per acre than the inventory mix with the Parboiled Rice Hulls included.
