Aluhayos Rock Wool Grow Cubes are stonewool starter plugs for soilless seed germination and cuttings. The porous structure holds water while letting air reach the roots, which is the same job rock wool has done in hydroponics for decades. They suit indoor gardeners, balcony growers and classrooms running simple propagation projects. Against peat or coco plugs, rock wool holds more water and stays wet longer, but it needs pre-soaking and pH adjustment before use, and it does not break down in soil.

These rock wool grow cubes are a soilless growing medium for sowing seeds and starting plants in hydroponic setups. The rock wool is highly porous, so it lets air through and absorbs water well. This supports healthy root development.
The cubes can be used without traditional soil. They suit indoor gardens, balcony planting, school laboratories and office greening projects.
