Grodan Growcube


Loose substrate, firm benefits
Are you looking for a porous and rigid substrate for your container cultivation? And do your cultivation methods place ease of watering high on your wish list? Then Grodan Growcube is the substrate for you. Growcube combines the qualities of clean and manageable rock wool substrates with the demands that are made of a loose substrate for containers or pots.

Growcube consists of small cubes which retain water extremely well. The rigidity of the cubes results in a substrate unit with many cavities, ensuring a continuously high air porosity percentage. This ideal water-air balance lays the foundations for an easy to manage crop.


Benefits for the grower:
  • Dry substrate with continuous high porosity
  • Easy watering
  • Good uptake of available water by plants
  • Porous and rigid substrate for use in containers
  • Water content and EC can be measured and managed in the substrate
