Par boiled Rice Husks/Hulls

I've practically given up trying to find usable pine/fir bark for use in my soil mix, but did find par boiled rice husks in a usable form.

I hear they don't break down as quickly as pine bark but do have excellent water retention characteristics.

Here is a breakdown:

PBH (Parboiled Rice Hulls)

• PBH Nature’s Media Amendment is the number-one choice for sustainable plant production
• 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
• As any organic media, there is decomposition over a long period of time, yet PBH remains stable during the typical growing plant production cycle
• PBH Nature’s Media Amendment is OMRI listed and WSDA registered for organic production
• PBH is extremely lightweight and highly compressed when packaged in a choice of standard or bulk bale
• PBH generates less waste and reduces storage requirements, handling and freight.
• 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 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 offers environmental, horticultural and economical advantage



Anyone have any experience with them?

I use a similar medium, on one of my deciduous trees, that uses the rice husks mixed with other materials. One nice thing about it is that it holds moisture really well and doesn't clump at all when wet.

Can you give me an idea of the particle size?

It's almost the consistency of a well ground mulch (small); it's called Organic Mechanics. It's made up of boiled rice husk, worm castings, coconut husk fibers and 10% what's labled 'organic mulch'. It containes no peat.

So I'm assuming the rice husks are the longer, larger pieces within this mix?

Yeah, the oblong pieces.

Thank you
