The Grodan GR-Slab 1000 × 150 × 75 mm is a high-quality stone wool grow slab for precise hydroponic cultivation and controlled irrigation systems. Through the even distribution of water and nutrients, the slab supports a stable root zone and creates optimal conditions for healthy plant growth.

The slab is ideal for professional grow setups as well as ambitious hobby growers who value a controllable root environment and efficient nutrient management. Thanks to the hydrophilic stone wool structure, moisture is evenly distributed and reliably stored, while simultaneously maintaining good oxygen supply to the roots.

The inert substrate itself does not bind any nutrients, thus enabling particularly precise control of the nutrient solution. This allows the plant supply to be precisely adapted to the respective growth stage.

The GR-Slabs are ideally suited for use with matching grow blocks and modern irrigation systems in hydroponic facilities.
