In terms of market share, orchids are one of the largest plant family grown in greenhouses all over the world. Our orchid substrates meet the highest standards of orchid-cultivation. The orchid market is a very dynamic and constantly changing market. At BVB Substrates we closely monitor the orchid market. Together with our in-house laboratories, we offer the best solutions to adequately respond to the changes in the orchid market. Growing methods and environmental developments are important pillars for us.

Wide diversity of orchid substrates

BVB Substrates is a well known supplier of substrates especially developed for orchids. We offer a great diversity of substrates for both pot orchids and cut orchids. There is a wide variety of orchids and each type has its own specific needs. This makes tailor made substrates even more important.  For example a Phalaenopsis and a Cymbidium have relatively  coarse roots, while the Miltonia, Dendrobium and Camrbia have a much finer root systems. In addition to the different needs of each type of orchid, the methods of the grower determine a big part of the composition of the substrate as well. 

Optimal composition

Thanks to the wide variety of available raw materials: bark in different sizes, coir, cocopeat and sphagnum, we are able to adjust each mixture to the growers needs. The following properties are taken into consideration when determining the optimal composition of an orchid mixture:

  • Pot size (9 cm, 12 cm, 15 cm or other)
  • Pot type (strongly draining or with a moisture buffer)
  • Desired humidity at the start
  • Moisture control during cultivation
  • Watering system (rain pipe / drip)
  • Wishes regarding recirculation


Bark is a resource that is quite common in mixtures for orchids. There are, however, several alternatives. We offer alternatives that can be used as a growing medium on its own or to be added to a mixture with bark. We only offer materials that have the required physical properties. Factors we can control are: moisture, airiness and stability. The overview below shows some of the possibilities.

Rock wool

  • Basacubes (1 cm­­ en 2 cm­­ cubes)
  • Rock wool fractions
  • Foam products
  • Aggrofoam­­ 10 m­­m­­
  • Aggrofoam­­ 19 m­­m­­


  • Cocoschips 2 – 6 cm­­ (m­­iddle)
  • Cocoschips 1 – 4 cm­­ (fine)
  • Cocogran Pit


  • Perlite nr 2 (0,6 – 3 mm)
  • Perlite nr 3 (0,6 – 7,5 mm)
  • Perlite double sieved (2 – 6 mm)

Sphagnum and turf

  • Sphagnum­­ (fine, 2 cm­­, fiber,)
  • Several types of turf in different sizes

Substrate requirements

It’s not easy to determine the optimal mixture for the best orchid substrate. Orchids have high demands when it comes to the substrates. BVB Substrates only uses resources and mixtures when it meets the strict conditions. We check the following properties (among other things):

  • Physical properties (stabi­lity, drainage and water m­­anagem­­ent)
  • Free of toxic or phytosanitary irregularities
  • Good processability of the substrate
  • Environmentally responsible use of raw materials
  • Possibility of customised production (grower, crop, pot size, retail)
  • Competitive pricing
