To maximize the efficiency of substrate use and the control that you have over the root zone of the plant, it is important that the right layout of slabs and cubes are used. The whole concept of the Cultilene stonewool system is to create as even or consistent a root environment as possible to maximize the use of the substrate.
The cubes should be evenly spaced along the length of the substrate so that each plant / dripper has the same volume.
The right dose size and drainage slits are calculated based on the volume of substrate per plant / dripper based on this principle as below. The dripper has grooves down the sides to allow the water to flow down into the substrate.
The flow of this water is spread evenly by the stonewool to refresh the nutrient solution around the roots. This is what we call the Cone. The Cone starts in the cube and spreads down and sideways. The cube will increase the width of the cone and the volume refreshed by the dripper giving more efficient water and fertilizer use.
This is vital in giving good refreshment and even water content, EC control and minimizing drain. The cube is also important in keeping the base of the plant dry. This is important for preventing basal disease issues.
The height of a stonewool substrate has a big influence on the water content. The higher the column of stonewool the bigger the difference in the water content from top to bottom. So using a cube will raise the column and keep the top of the cube dry.
Slab height = 75 mm
Cube height = 65 mm
Total column height = 140 mm
If the plant or plug is placed directly into the slab, then the dripper also has to put directly into the slab. This gives many potential issues.
The Cultilene system using plugs, cubes and slabs is well tried and tested over 30 years.
