Rockwool cubes for hydroponic growing systems

Cultiwool rockwool grow blocks provide a structured root zone for hydroponic cultivation. The donut-ring planting hole and bottom drainage grooves support even wetting and drainage through irrigation cycles.

Stone wool is an inert growing medium, allowing you to manage nutrient strength, moisture and pH through your irrigation programme.

Available sizes and quantities

• 150 × 150 × 150 mm: a case of 48 cubes or a pallet of 768 cubes.
• 150 × 150 × 100 mm: a pallet of 1,280 cubes.
• Donut-ring planting hole for inserting a rooted propagation plug.

From propagation to a larger root zone

Use these rockwool cubes when rooted plugs are ready to move into a larger block. Prepare the growing medium and manage irrigation according to your crop and nutrient programme.
