This uniquely processed rice hull amendment is a readily renewable resource requiring no mining or land disruption to produce. As so many growers have learned, it is a perfect replacement for perlite in the growing media - providing a less dusty mixing environment, lower basic cost and decomposition over time, while remaining stable during the typical plant production cycle.

  • PBH Nature's Media Amendment is OMRI listed and WSDA registered for organic production.
  • Extremely lightweight and highly compressed when packaged, it generates less waste and reduces storage requirements, handling and freight.
  • De-compressed, it is 7.5 cu. ft. Its physical size, shape and bulking properties produce optimum air-filled pore space, water-holding capacity and drainage, while its natural color blends with other media components.
  • Uniquely processed to ensure purity, PBH Nature's Media Amendment is sized, cleaned and subjected to a series of heat treatments that collectively sterilize the rice hulls and render any residual rice kernels, weed seeds or disease pathogens non-viable.
  • Greenhouse-proven PBH Nature's Media Amendment offers environmental, horticultural and economical advantages. Growers who rely on it gain sustainability, reduce input costs and sacrifice nothing in terms of plant quality.


  • Biodegradable
  • Improves Water Holding Capacity

LOVE these!

I use rice hulls in my garden every year for drainage and water retention. Since I began using them, I noticed great results! I love that it's a sustainable product that's safe for my cat who likes to roll in them...

great path material

I use rice hulls to cover my garden paths, which are largely clay. I'm hoping that over time they will help to morph the clay into something more pleasant. Plus they feel marvelous on bare feet! I also use them as a mulch as they hold moisture beautifully

Great product!

I have used rice hulls in my potting media (along with coir and oyster shells) for over a decade. Frankly, it took me 10 years to use up the first bag. Yes, it's expensive to ship (one reason I wish there was a 25 lb. bag offered) but it lasts forever, as it's extremely compressed. I have had as good, if not better, results with hulls than I did with perlite and vermiculite. As someone who has mixed tons and tons of commercial potting soil in the past, I appreciate using a product that won't kill me, if I don't wear an air mask!

good mix

I added a bag of rice hulls and two bags of chicken manure to an existing raised bed. The chard and lettuce that I planted in the bed performed beautifully. One of my more successful fall gardens. I like the way the rice hulls helped the soil to retain moisture.
