|Short Description||This is a relatively new soil amendment requiring no mining or land destruction to produce. Many growers agree, it's the perfect replacement for perlite. Extremely light weight, it produces the optimum air-filled pore space, water-holding capacity and drainage. Uniquely processed, the rice hulls are steralized by par boiling, giving their name "PBH" (par boiled hulls), steaming and hot air drying. This assures there are no rice kernel residues, weed seeds or diseases. It's now being introduced in a wide variety of growing applications by adding it with peat, coir and bark at the rate of 10-30% of total growing media, so the higher the (PBH) ratio, the lighter the growing media will be, offering better drainage and better root development. It has a pH range of 6.2 to 6.6 and provides less than 1% nitrogen content so fertilize accordingly.|
- Great soil amendment Review by SLWL
- I have clay soil with few nutrients; we get little rain. Ordered rice hulls and coir bricks from Pinetree 4 or 5 years ago. I add to planting beds every spring - what a difference! I've tried compost and potting soil and other products for 20 years, but never saw much change until adding rice hulls and coir to the compost (hulls and coir don't add nutrients). It's still a challenge to garden in the high elevation desert, but this really helps. (Posted on 2/18/14)
