We use selected, and whenever possible, RAL-quality raw materials in our professional substrates. The quality of the raw materials and their composition determine the properties of the substrates. Please click on the raw material that you would like to learn more about.

The raw material peat comes from raised bogs and is comprised of sphagnum mosses. It is a completely natural product and is especially good for horticulture due to its excellent chemical, physical and biological properties. For years, white and black peat have been the most important raw materials for substrate production. Substrates containing peat meet the high demands of modern controlled plant cultures thanks to the complex interaction between substrate, fertilizer, plant material and cultivator. A cultivation with safe substrate is of existential importance for gardeners.
One can differentiate between black peat, which is older and more decomposed - the original plant structure can hardly be recognized -, and white peat, which is younger and less decomposed. The structure of sphagnum mosses can partially still be seen. Sphagnum peat is known for its low nutrient content and low pH value.
1.1 Black peat
Black peat has a high puffer capacity for nutrients and can store water for a long period of time. Only adequately frozen black peat finds use in substrate production. Peat that was not frozen would get hard after drying and would not be able to absorb water well.
1.2 White peat
White peat is structurally stable and has a high pore volume with high air capacity. White peat quickly absorbs large amounts of water but also releases these again relatively quickly. This is an important quality when cultivating with, for example, a water retention irrigation system. White peat gives structure to a substrate and promotes air capacity, drainage properties and capillarity, which makes it an important component for substrates.
The properties of white peat depend strongly on its extraction and fractionation. White peat is pricked as sod or harvested as milled peat. Sod peat retains its coarse structure, while fractionation severs the structures. The coarser the structure, the better the desired air capacity will be.
Today's substrate production uses German, Irish, Baltic, Russian, Finnish or Swedish peat. Differences in physical or chemical properties can be found depending on origin, age and harvesting method. Part of Brill's expertise is being able to develop Brill substrates with the desired substrate properties, regardless of the climatic situation in the region of origin and of the regional availability of different types of white peat.
Our peat must pass a quality test before use.
LignoDrain® is made of untreated, local pine wood without bark. The structure of LignoDrain® resembles wood chips and has a consistent grain with a low share of fine material. The smooth surface without fraying presupposes a low and calculable N-fixation. In the substrate, LignoDrain® has a stabilizing effect on the structure, increases drainage, improves air capacity and promotes healthy root growth.
LignoDrain® is a high quality renewable aggregate with good cost effectiveness. LignoDrain® makes up 30% of our substrate Ligno-Mix C.
LignoTer® is a substrate fiber compost made by Brill, comprised of RAL-quality substrate fibers from local pine trees and RAL-quality substrate compost. Both materials have been used for years in Brill substrates.
The organic wood fiber, certified for organic horticulture, can be found in Brill BIO substrates and is used as a basis for the LignoTer® - substrate fiber compost processed by Brill. LignoTer® is a natural, renewable resource of homogenous and consistent quality. LignoTer® improves the water dynamic in pots, increases drainage and leads to quick drying of the substrate surface. LignoTer® makes up 33% of our Ligno-Pot substrates.
CocoSol® is 100% coconut husk without additives and can be used as an aggregate for many substrates. CocoSol® is produced by Brill and is certified for organic horticulture according to EU-Regulation 834/2007.
CocoSol® is perfect as an aggregate for substrate production. With it homogenous composition, CocoSol® promotes the structural stability and air capacity of the substrate - this makes the substrate flow better and makes it easier to process and rehydrate.
CocoSol® is a renewable raw material that is produced in large numbers as a by-product of coconut production. While coconut fibers have long been in use, e.g. for mattresses, the fine material has just started being used in horticulture, which can be seen as a means of recycling. This is unrivalled by thermal recycling. The raw material is transported in dried and compressed blocks by ship, which minimizes the CO2 emissions caused by transportation.
CocoSol® can be found as an aggregate in Brill BIO substrates, among others.
Alongside CocoSol®, CocoDrain® is the second coconut aggregate produced by Brill and is also certified for organic horticulture according to EU-Regulation 834/2007.
CocoDrain® is comprised of 100% treated and washed coconut husk material, without any additives. CocoDrain® is an optimal mix of fibers, chips and fine material. It is structurally stable and especially promotes the substrate's air capacity. The water distribution in the pot is also improved, and the substrate can always easily be rewetted.
CocoDrain® is a renewable raw material that is produced in large numbers as a by-product of coconut production and is unrivalled by thermal recycling. The raw material is transported in dried and compressed blocks by ship, which minimizes the CO2 emissions caused by transportation.
CocoDrain® can be found as an aggregate in many different substrates, especially in container substrates with a coarse structure.
Only RAL-certified compost is used for the manufacturing of our substrates and potting soils.
Due to its nutrient content, RAL-certified substrate compost can make up a maximum of 40% of a substrate.
Substrate compost has physical properties well suited for substrates; it improves rewetting and increases the puffer ability for nutrients.
The biological activity of the substrate is positively influenced, which improves the release of nutrients. Substrate compost is used as an aggregate in substrates for organic horticulture and in potting soils.
Natural, sieved bark material serves as a long-lasting and structure improving aggregate in crop substrates.
Perlite is a mineral aggregate made of volcanic rock. Perlite has a white color, is very light and porous and is free of plant harming substances. Perlite has a very high air capacity, is easily rewetted, is structurally stable and has a neutral pH value. Perlite is used as an aggregate and can comprise 30% of a substrate; it ensures the air capacity in the substrate and promotes rewettability and capillarity.
Clay is a very important aggregate for substrate production. Clay absorbs nutrients and slowly releases them during the growing process. This prevents nutrient erosion. Clay also has good water retention ability and ensures quick rewetting in the substrate. Clay increases the volume weight and stability; clay can also improve structural stability.
Benefits of clay substrates: high crop security and a consistent crop. Alternatively to clay, clay granulate can be used, which can provide similar results in the substrate at a much lower quantities of expenditure.
This mineral aggregate improves the substrate's structural stability. Expanding clay is manufactured in a thermal procedure and can be used in many different areas of horticulture. The high structural stability of expanding clay improves the air capacity and drainage quality of substrates. Expanding clay is especially good for container substrates with a long growing time or for substrates designed for tree pits.
Washed and sieved sand with a very fine grain improves the rewetting of substrates, increases the volume weight and offers more stability.
