The substrate base consists of two JMS mineral components, inert and totally natural

• The wool comes from fragments of diabase extracts in southern Germany; these elements in an exploded heated to 1200 °, which is supplied by charcoal furnace. The incandescent filaments are oriented in a centrifuge and automatically cut into regular lengths. These filaments, on cooling, contract very airy flakes.
  
  
  • Vermiculite strata from mica, primarily imported from China. These layers are immersed in a furnace at 1000 ° and under heat shock, éclantent small "accordion". These elements are neutral, and texture, they can retain the fertilizer ions from the dissolution of the slow-release fertilizer (slow release fertilizer) return added to the substrate.
  

Two elements are added to the substrate JMS

• A fertilizer with slow restitution allowing fertilization adapted to the selected plant. This fertilizer is at the end of the crop cycle, completely consumed, leaving no traces of heavy metals.
  • A water-retentive which increases the capacity of water retention and reduces the frequency of watering in the case of high temperatures. These hydro-retentive gradually and completely degrade under the influence of UV rays.
  

The qualities of the substrate are JMS

• A very low density (0.1 sec), thus supporting a very light crop
  • A large capillary which ensures a very easy watering
  • Large capacity of water retention while maintaining excellent root aeration
  

The substrate JMS is handled once waterlogged. In this state, it is not messy, it is pleasant to the touch and is less abrasive than peat. In a day and heavy use, it is preferable to wear gloves light work.
