With our JBH systems you can obtain the most efficient way of growing and also at the same time reduce the costs for substrate, water and fertilizer. JBH systems are designed for each individual customer and for all different circumstances. Growing media are available in many shapes and materials. There are substrates, which can only be used for 1 year such as rock wool, but we also deliver OXYGROW foam substrate, which lasts up to 10 years. There are “dry” and “wet” substrates and each substrate has its own characteristics. Which substrate to choose depends on many items such as the time that the substrate should be used for a specific culture, the best preferred way of watering, the costs and how to dispose it after use. In case local substrates are available we are willing to analyze these, to give a good advice about the possibilities and the most efficient use of these substrates.
