We use these seed free rice hulls as an organic weed preventative on many of our plants. We also mix it into some of our potting soil depending on what the plant prefers. Not a bad option to make your containers lighter and easier to move. These bales are very compressed so we recommend starting with just one bale and then seeing if you need more. Unfortunately, we can only sell it by the full bale. More information available here: https://www.riceland.com/rice-hull-product
