The supplier where custom solutions are standard

The quality of the substrate defines the quality of the final product. As innovative as the horticultural sector is, growers are constantly seeking ways to optimize crop growth. That’s why BOL keeps around 40 types of raw materials and a similar number of fertilizers in stock. Together forming the basis for the approximately 1000 different substrate products we supply to professional horticulture.

Tailor-made mixes

At BOL, we specialize in developing and producing custom substrate blends tailored to the specific needs of your nursery and crops. As a flexible, smaller-scale supplier, we can easily switch between blends and respond quickly to changing demands. Year-round delivery is no problem—thanks to our extensive stock of raw materials stored at our modern facility in Hoek van Holland. From major components like peat, clay, and coir to materials such as volcanic rock, bark, and green compost, we’ve got it covered. We're also focused on innovation. Take wood fiber, for example: a sustainable alternative that helps reduce reliance on peat.

Quality and continuity guaranteed

We source our raw materials from across the globe, including Ireland, Germany, the Baltic States, Sweden, and even further afield, such as India and Ghana. Thanks to close partnerships with trusted importers, BOL ensures consistent quality and reliable supply. Our experienced staff also carry out visual inspections upon arrival, immediately detecting any variations in quality.

Large covered storage space

All products have ample space on our site, allowing us to stock raw materials that are less available during the winter period. Having large stocks also enables us to efficiently combine batches, ensuring the consistent composition of raw materials.
