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
