Grow-Cubes are small 1/4” cubes of rockwool.
There are several advantages:
Grow-Cubes stack on top of each other leaving air space in between them this promotes root growth.
Even if you water a lot, the Grow-Cubes will not get water logged as the increased surface area allows for much better drainage
You have less algae growth on the top than with the smooth surface
Very easy to mix with any other potting mix
Mixing Grow-Cubes in with clay pellets? The Grow-Cubes will help spread the water in the container as well as keeping a water buffer in between the watering
Lightweight; approx. 1/10 of the weight of a bag of potting soil
