Hullgrow WEED FREE Horticulture Grade Rice Hulls is ideally suited for horticultural use. The proprietary Hullgrow process eliminates problems occurring in other rice hull products; specifically the removal of weed seed that may otherwise compete with crops or attract pests that disrupt or destroy crop growth. Applications for Hullgrow include, but are not limited to, greenhouse, vegetable transplant, soil mixing, crop aeration, and general aggregate substitute.
Hullgrow was created in 2007 in Davis, CA with a mission of manufacturing quality products made from agricultural waste for the horticultural industry. Hullgrow has developed a proprietary technology process that converts raw rice hulls into a weed-free, rice hull aggregate for use in growing mixes and soil amendments.
