Added this to poor draining soil and was left with straight mud, worse than what I started with:
"A Parboiled Rice Hulls (PBH) disadvantage that cannot be overcome is their shape. PBH resemble the shape of a tiny canoe with a long slender pore shape. If a growing mix’s other components are poor quality, such as a peat with a lot of fines, these fines can fill the PBH pore space and actually hinder drainage and increase the water holding capacity of a mix.
A growing mix is only as a good as its components. PBH cannot work independently of the other mix components. The highest quality PBH are no match for a mix composed of poor quality peat, bark fines and other materials that are commonly available. Quality raw materials at their earliest stages lay the foundation for growing success."
