Rockwool rockwool slab 100x20x7.5 cm
Horizontal fibre sheet with the same characteristics as Classic but with a higher fibre density to resist vertical crushing due to the persistence of sub-acidic conditions (pH < 7) over periods of more than 12 months. It is ideal for promoting the generative qualities of plants. Classic is a robust and versatile sheet that allows good WC and EC control and optimal rooting. It can be annual or multi-year (higher density). WC tends to be lower at the top (40%) and higher at the bottom (60%).
