Par Boiled Rice Hulls by the bale
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.
Can also be used as a mulch!

To be used as aeration at 30% of total soil volume
The 30% of soil volume would consist of 1 part Rice hulls with 2 parts pumice for ideal aeration of soil.
If going for long term no-till we suggest using Half Rice Hulls and Half Pumice or Lava Rock.
