Cultiwool Rock Wool Slab – Rock Wool Slab for Hydroponic Growing

Frequently asked questions

• What are the dimensions of the Cultiwool rockwool slab?

  Each slab measures 1000 mm long, 150 mm wide and 75 mm high. That elongated format makes it ideal for row crops and automated systems.

• How many plants can I put on each slab?

  It's designed to hold between 3 and 5 plants, depending on the size of the pots or the growing system you use. Getting that density right is key so that each plant has its own root space.

• Can it be combined with rockwool cubes?

  Yes, it is fully compatible with rockwool cubes for direct transplanting. That way you can go from propagation to cube to slab without the plant suffering at any change of medium.

• Which growing stage is it recommended for?

  It is particularly recommended for hydroponic systems and for flowering crops with high nutritional demands and a need for stable water supply. It fits especially well in the later stages, where root development determines the final yield.

• Does it work with drip irrigation?

  That is one of its strong points: it integrates easily into drip or automated irrigation systems, and even works with sensors. This gives you very fine control over the growing environment in technical rooms or greenhouses.

• Does it reduce the risk of root disease?

  Yes. Being an inert, clean medium, free of pathogens and residues, it lowers the risk of root disease. Its high aeration also prevents waterlogging, which is behind a good share of those problems.
