Description
Studies have proven that rice hulls can efficiently replace perlite in your potting soil mixes and is much better for the environment.
We have independently heavy metal tested the contents and will only work with PBH for our rice hulls because of how clean they have tested. Beware of cheap rice hulls potentially full of heavy metals.
Parboiled rice hulls are produced by steaming and drying rice hulls after the milling process. This results in a lightweight and consistent product that is free of viable plant and/or rice seed
