We have run out of stock for this item.

6inch HUGO Rockwool Block

The Hugo 6" cubes are large enough for most single plant cycles. The hole size (apprx 1.5inch) is perfect for most peat plugs.

Depending on the plant grown you will need to monitor the growth of the roots and be ready to transplant to a larger pot if the roots reach 1inch or more from the bottom of the Hugo rockwool cubes.


  • Saturate your rockwool cube with pH (5.5-6.5) water when starting cuttings
  • When transplanting ensure you use the same strength nutrient solution to soak the new media
  • If submerging your cubes hold under water until bubbling stops
