Why are rice hulls better than perlite?įrom an environmental standpoint, rice hulls are the best choice. ![]() In the past, hulls were discarded but luckily we’ve learned that they can be repurposed. The process is that after the rice is harvested, millers remove the hulls and then parboil them at a high heat to kill any weed seeds, bacteria, and diseases. Rice hulls are the thin papery casings on rice, similar to corn husks, that act as a protective covering. A 50 pound bag of Organic Rice Hulls is $70 at The Soil Makers. What are rice hulls? Above: As of now, in the US, it’s tough to source store-bought soil that uses rice hulls instead of perlite, but packages of rice hulls alone (sold as a soil amendment) are easier to find. But did you know that we should also consider replacing perlite, the little, white, styrofoam-looking balls often mixed into store-bought soil to provide aeration and drainage? While perlite is quite useful and effective, there is actually a more sustainable and environmentally friendly option now: rice hulls. Most of us gardeners know by now that we should trade peat moss for more sustainable choices (like coconut coir), because of the negative consequences of harvesting the stuff on the plants and wildlife native to the peatlands-not to mention, depleting our planet’s peatlands, which store three times as much carbon as forests, would worsen global warming.
