Knowledge

Wood peat is an engineered wood and bark based component designed for professional horticulture substrates. It is made from circular softwood and bark chips, primarily Estonian grown Baltic pine. The raw material is carefully selected and processed to achieve the physical properties required in professional growing media. The result is a consistent structure, an improved air–water balance, and reliable root-zone performance. This makes wood peat a valuable renewable component in high-performance substrates alongside traditional peat.

FAQ

Here you’ll find answers to the most common questions about Miksgrow substrates, ordering, and technical support. If your question isn’t here, contact our team – we’re happy to help you choose the right substrate or answer any questions.

Miksgrow substrates are designed for a wide range of crops and cultivation systems, providing reliable performance as a versatile greenhouse and nursery growing medium. To select the right Miksgrow substrate, consider your production stage and crop requirements:

  • Miksgrow MXX – A finer grade specifically formulated for seedling production and propagation, where uniform moisture distribution and good seed-to-substrate contact are essential.
  • Miksgrow MYY – A coarser grade designed for potting up, repotting, and nursery container cultivation, offering improved drainage and air porosity for established plants.

 

Both grades are suitable for ornamentals, vegetables, and nursery plants across multiple production stages. For irrigation system compatibility, consider that the finer MXX grade retains more moisture and requires less frequent watering, while the coarser MYY grade provides better drainage for overhead or drip irrigation systems with established root systems.

Miksgrow peat-free substrates are produced mainly from softwood raw materials such as Baltic pine, sourced from sustainably managed Estonian forests. These softwood fibers provide strong structural stability during cultivation, helping the substrate maintain its physical properties throughout extended production cycles.

To further improve performance, Miksgrow also incorporates bark fibers. Bark naturally contains higher levels of phosphorus and potassium than standard wood fiber, which helps enhance the substrate’s nutrient profile and supports better overall nutrient availability for crops.

Yes. When transitioning to Miksgrow peat-free substrate, irrigation practices typically need some adjustment. During the first production cycles, monitor moisture levels closely to understand how the substrate behaves in your specific system. Using moisture sensors can be especially helpful, as they provide objective readings and reduce the risk of over- or under-watering.

It is also common for the surface layer to dry out faster, which can give the impression that the whole substrate is too dry. In most cases, the lower profile still retains adequate moisture for the root zone thanks to the substrate’s stable, non-compacting structure. For best results, rely on regular measurements and consistent monitoring rather than surface appearance alone.

As with many wood- and bark-based growing media, Miksgrow can temporarily bind a portion of nitrogen as microbes break down the carbon-rich fibers. To account for this, Miksgrow is enriched with a starter fertilizer that includes higher nitrogen levels, suitable for both short and long crop cycles, helping ensure adequate nitrogen availability during early establishment.

During active growth, some adjustments to nitrogen fertilization may be needed, depending on the crop and production system. In practice, consistent irrigation management and the substrate’s uniform moisture distribution can improve nutrient uptake efficiency and may help reduce overall water and fertilizer use.
