Mushroom board is a type of wood product derived from wooden boards originally used to line the boxes of mushroom crops. The boards are salvaged and repurposed, showcasing a unique texture and rich colour tones. The process of growing mushrooms erodes the soft fibre of the wood, raising the grain and creating a one-of-a-kind surface that is aesthetically pleasing. These boards are in high demand for their natural resistance to moisture and versatility, finding applications in various projects, including accent walls and siding for homes or buildings.

Mushroom board is a type of wood used in commercial mushroom growing
Mushroom boards are made from softwoods like hemlock, cypress, and cedar, which are suitable for mushroom cultivation due to their ability to withstand deterioration from soil and moisture. The boards are approximately 8" wide and vary in thickness from 1" to 0.75". They go through a rigorous process to remove organic soil, including kiln drying and wire brushing, before being used for projects.
The unique texture and patina of mushroom board make it aesthetically pleasing and versatile. The open grain and smooth surfaces of the boards create a great look for ceilings, walls, or siding on homes or buildings. The natural resistance to moisture and light weight of the wood make it a sustainable and sought-after product.
The wood used for mushroom boards degrades over time and needs to be replaced every few decades. This ensures a constant supply of mushroom board for various applications. The consistent sizing of the boards also allows for efficient installation. Mushroom board is a green recycling process, as the wood is not discarded or sent to landfills when retired from mushroom farming.

The boards are made from softwoods like hemlock, cypress and cedar
Mushroom boards are wooden boards used to line the boxes of mushroom crops. The boards are made from softwoods like hemlock, cypress and cedar. These types of wood are ideal for growing mushrooms because they can withstand the deterioration caused by soil and moisture. The process of growing mushrooms leaves a unique texture on the wood. The erosion of the soft fibre in the wood raises the grain, resulting in a one-of-a-kind finish.
Mushroom boards are sourced from wood boxes used for growing mushrooms. The softwood boards are exposed to soil, fertilizer, manure and mushroom spores for several years. This organic activity, combined with the natural elements, creates a unique patina on the wood surface. The resulting texture and colour tones of mushroom boards vary, ranging from rustic to modern looks.
The process of cultivating mushrooms on these softwood boards results in a beautifully sculpted surface. The open grain and smooth surfaces of the boards make them aesthetically pleasing and versatile. Mushroom boards can be used as accent walls, ceiling panels, or siding on the exterior of homes or buildings. The natural resistance to moisture and lightweight characteristic of the wood make it a sustainable and sought-after product.
The boards used for mushroom cultivation are replaced every few decades due to degradation. This ensures a constant supply of mushroom boards for reclamation and repurposing. The consistent sizing and high supply of mushroom boards make them efficient and easy to install. The boards are typically cleaned, kiln-dried, and wire-brushed before being used for projects.

The wood develops a unique texture and colour from the growing process
The process of growing mushrooms for mushroom board involves unique techniques that result in distinctive characteristics in the wood. The growing process begins with carefully selected wood substrates, typically hardwoods like poplar or beech, which are then prepared and treated to encourage mushroom growth.
During the cultivation process, the wood is inoculated with mushroom spawn, which are the mycelium spores of specific mushroom species. These spores germinate and the mycelium begins to colonize the wood, breaking down the wood's components and extracting nutrients. Over time, the mycelium grows into a dense network of thread-like hyphae, which gives the wood a unique, intricate texture.
The presence and growth of the mycelium affect the colour and appearance of the wood. As the mycelium colonizes the wood, it secretes enzymes and pigments that can alter the wood's original colour. The resulting colour variations can range from subtle hue changes to more pronounced tones, often resulting in a beautiful, natural patina. This colour transformation is a distinctive feature of mushroom board, and each piece of wood develops its own unique colour profile depending on the mushroom species used and the specific growing conditions.
Additionally, the growth of the mycelium can also affect the texture of the wood. As the hyphae intertwine and form a network, they can fill in the natural pores and grains of the wood, creating a smoother and more even surface. In some cases, the mycelium can also cause the wood to become slightly denser and more compact, resulting in a unique tactile experience when touched or worked with. Overall, the growing process for mushroom board results in wood with a distinctive and naturally enhanced texture and colour profile, making each piece truly one of a kind.

After use, the boards are cleaned, kiln-dried and wire-brushed for reuse
Mushroom boards are derived from wooden boards that are used to line the boxes of mushroom crops. The boards are made from softwoods like hemlock, cypress, and cedar, which are ideal for growing mushrooms because they can withstand deterioration from soil, moisture, acidity, and heat. After the mushrooms are harvested, the boards are cleaned, kiln-dried, and wire-brushed for reuse.
The process of growing mushrooms leaves a unique patina on the boards, with a beautifully sculpted surface that is difficult to reproduce. The erosion of the soft fibres in the wood raises the grain, resulting in a one-of-a-kind texture. This texture, along with the natural resistance to moisture, makes mushroom boards a versatile product for various applications, including walls, ceilings, and siding on homes or buildings.
To prepare the boards for reuse, they undergo a rigorous process. First, they are cleaned of any remaining organic soil or manure. Then, they are kiln-dried to remove any remaining moisture and kill any potential pests or mould. Finally, the boards are wire-brushed to smooth out the open grain surface and enhance the unique texture.
The cleaning and milling process transforms the reclaimed wood, giving it a new life outside of the mushroom farm. The boards can be cut and shaped to meet specific size and shape requirements, making them versatile for a variety of projects. The natural ageing process of the wood, combined with the absence of staining or sealant, ensures that mushroom boards remain beautiful and graceful for years.
Overall, the reuse of mushroom boards is a sustainable and aesthetically pleasing practice. The boards are upcycled and given a new purpose, preventing them from being discarded or retired to landfills. The unique characteristics of the boards, combined with their consistent supply and sizing, make them a desirable choice for those seeking a rustic and natural look in their projects.
