BVB Wood Fibre for growing media

Over the past decades the need for complementary materials in growing media had risen. We process a variety of complimentary raw materials, among which a type of Wood Fiber called BVB Wood Fiber, into our products. This article focusses on the exceptional production process that makes this material perfectly suitable.

Our Wood Fiber, being a renewable raw material, is produced out of circular, European, PEFC certified wood. It is available throughout the year, and its quality is not influenced by weather conditions. Thanks to its low bulk density environmental impact of transportation is relatively low.

How we treat our Wood Fiber for growing media

The first thing that makes BVB Wood Fiber different from commonly used Wood Fiber is the type of wood that is used to create the fibers. We only use 100% pure hard wood logs from European spruce trees. This specific type of tree is used, because it provides wood with a strong fiber structure ensuring stability throughout the entire growing period. No branches, needles or left over wood is used in this raw material, because this can cause impurities in the end product.

In addition to the quality of the wood that is used to create BVB Wood Fiber, the production process of the fibers has specific steps that guarantee top quality as well. The Wood Fiber we use in our BVB Substrates products goes through four main steps which makes it different from commonly used Wood Fiber.

Step 1 – Steam treatment

By steam treating the Wood Fibers we not only make the material clean and safe to use, we also loosen the fiber cells to make sure we get the desired texture in the next steps of the process.

Step 2 – Grinding

By grinding the Wood Fiber we create a “woolly” texture exposing more surface area. This brings beneficial properties to the growing media.

Step 3 – Fluffing

After the fibers have been created we use machines to fluff the Wood Fiber. This way the fibers are loosened to improve uniform blending in the next step.

Step 4 – Mixing

The final step of using BVB Wood Fiber in our growing media is ensuring it is optimally mixed in with the other raw materials. We use modern mixing lines to ensure uniform blending of the different raw materials. If Wood Fiber is not adequately mixed in, it can form lumps with other raw materials, which can cause issues when used. The fiber lumps can heat up during the growing period, disturbing hydro dynamics and impeding root growth.
