Rice Hulls - Par Boiled

These environmentally sustainable materials are highly absorbent and improve drainage, water holding capacity, and aeration. In fact, they are one of the top choices for greenhouse growers looking to enhance their soil.

As opposed to perlite, pumice, vermiculite, and biochar, rice hulls decompose after only one season of use. This is beneficial for increasing organic matter in your vegetable garden, although annually reapplication is necessary to reap the benefits of moisture regulation and aeration.
