Rockwool Cubes & Slabs

Rockwool is a modern alternative to soil. It is lightweight, completely sterile and non-toxic. Its unique structure provides roots with a perfect air to water ratio. The classic hydroponics medium, Rockwool is perfect for a wide variety of hydroponics systems.
Rockwool is an inert medium, completely free of nutrients and is usually available in a pH balanced form (although some rockwool may be slightly alkali).
No1hydro stock a complete range of rockwool products for different uses including: cubes for propagation, shredded mixes (with coco or polyurethane foam) known as ‘mapito’, horizontal slabs for trough systems (‘Exact’ slabs), slabs for use in vertical systems such as the Agrowtent (‘Maxxima’ slabs) and blocks for use in NFT or flood and drain systems (available in a variety of sizes).
Nutrients that are formulated for hydroponics are usually recommended for use with rockwool.
Soak in pH adjusted nutrient solution (pH 5.5 is ideal) and drain before use
