Rockwool Cube 4×4×4 cm is a compact growing medium for starting seedlings and rooting plants. The porous structure of rockwool retains water while allowing air to reach the root zone.
The cube is particularly suitable for hydroponic systems and other growing methods where an airy growing medium with good water retention is required. Once established, the plant can be transferred together with the cube into a larger growing medium or hydroponic system.
Moisten the rockwool cube with suitable water or nutrient solution before use. Place the seed or plant in the planting hole in the centre of the cube. Monitor the moisture level and avoid keeping the cube excessively wet.
