PBH Nature's Media Amendment is your number one choice for sustainable plant production — and a whole lot more. 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.
