Grodan Growcubes Box Bulk (72 gal)
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 or Growchunk is the substrate for you. Grodan combines the qualities of clean and manageable rockwool 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. Use Growchunks for even higher water retention. The rigidity of the cubes and chunks 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.
