All JBH systems are economical and flexible gutter-systems to support the substrate. Economical because the drain water is collected for reuse and flexible because we can adjust the sizes of each system to the specific wishes of each customer. For vegetables we offer systems isolated from the ground with separate drain water discharge to avoid roots growing into the drain gutter. The most advanced technology is a system with root temperature control. This is developed especially for countries with a hot climate. For flowers we offer various systems on the ground as well as systems raised from the ground for the best growth situation and air circulation. We supply systems made of Polystyrene(EPS), Polypropylene (PP) and Steel. These are extremely solid systems to support the substrate and to collect the drain water. The system is adjustable in height and width.
