Many growers have already learned that PBH/Nature's Media Amendment, par-boiled rice hulls have many advantages! Growers choosing PBH/Nature's Media Amendment reduce costs, gain sustainability, and do not sacrifice plant quality.
For Greenhouse Production as a Replacement for Perlite:
- Lower basic cost than perlite
-
Creates optimum porosity, drainage and stability
-
Requires little or no adjustment to fertility and irrigation
-
Dramatically less dusty than perlite
-
Less freight, labor, storage and packaging
-
Natural color blends well with other media components
For Container Planting:
- Topdressing with 1 to 2 inches dramatically improves weed control.
- Reduces potential for drought stress.
- Increases porosity in growing media, which allows for more air flow and better water drainage.
- Better airflow and drainage around the roots encourages strong growth and reduces the risk of disease development.
- Minimal drift or floating within potting mixes.
- As a byproduct of rice production, rice hulls are a renewable and sustainable product.
PBH Rice Hulls add porosity to the rooting substrate that allows improved movement of water and oxygen to aid root development and reduce the incidence of disease. At 20% of the total volume of the root substrate, PBH provides similar drainage and air-filled pore space as a 20% perlite mix. Once the volume of PBH is increased to 25% of the total volume, it provides a higher level of drainage and air-filled pore space than 25% perlite. The highest shoot and root growth occurred for plants grown in root substrates containing 20% to 30% PBH.
Recommendation is for rice hulls to be approximately 10-30% of total growing media.
- Growing media with 20% PBH has approximately 10% aeration (air-filled pore space)
- Growing media with 30% BPH has approximately 20% aeration.
- Growing in a 4 or 6 in. container needs a minimum of 10-15% aeration.
