Cultilene 10mm Mini Rockwool Cubes 75L
Cultilène Mini Cubes are a cube-like loose substrate made of rockwool. Mini Cubes provide a perfect water buffer with a very high water-holding-capacity. The water content in a pot of Mini Cubes is at a maximum of 85%. Not only are Mini Cubes lightweight but they also provide large air spaces as there are always open spaces amongst the cubes. Mini Cubes maintain their cubic shape throughout cultivation. Due to these unique features, the substrate typically has an air-space volume of 30% which depends on the size and shape of the pot. This means that long irrigation cycles are possible without causing lack of oxygen to the roots.
