Quality raw materials play crucial role in growing media producing
Sphagnum peat moss as a component of horticultural growing media is very important because of the unique main properties of the sphagnum cells to hold and release water. However, there are many ways in which these important features can be significantly changed. Only experienced peat extractors and processors can provide peat that will be ideal for the most demanding grower.

Size matters.
The root system of each plant has its own size and it changes as the plant develops. The soil that was suitable in the first months must be changed so that the growing roots have sufficient air access and water circulation. This means that the size and configuration of the peat particles must correspond to a certain root system. It is very important!

Special block and milled peat screener

More than 90 % of all growing media are based on black and white peat. Premium quality raised bog peat has proven to be the constituent with the most beneficial properties for use in growing media. It is the first choice in modern professional horticulture. The quality and performance of growing media are predetermined with the right raw material components. The harvesting method, harvesting technique, structure, moisture content and processing determine important physical factors such as air and water capacity or structural stability.
Provision of air exchange
The roots are breathing. One of the most common disorders of root development is related to growing media compaction. Substrate with a loose, light and stable structure is vital for horticulture

Careful processing of raw materials meets the highest horticulture standards

Milled peat moss
The beneficial physical properties of peat moss are due to the cell structure of the sphagnum moss which provides a large volume of pores filled with water and air.
Fine screened white peat. Base for propagation substrates.

Coarse structure white peat. Base for transplantation substrates.

Black peat fine strucure peat. Base for blocking substrates and different mixes

Black peat medium structure. Used for general potting together with white peat

Sod (block) peat
Sod peat fractions. Specially harvested and processed peat raw material which provides a reduced amount of fine particles and a very high structural stability to ensure drainage and air capacity in substrates. Besides milled peat this is the most important constituent in well-structured substrates for pot plants, shrubs, trees or soft fruits where high structural stability is required.
