Product Description

These small Rockwool croutons are ideal for use as a hydroponic rooting medium. They can also be added to other mediums for a bespoke mix. They are clean, lightweight and well aerated and perfect for passive growing in pots or using in a Wilma system.

What They Are Used For

Grow Cubes are for use on their own as a medium or in collaboration with other mediums such as clay pebbles. Rockwool has a fibrous structure capable of holding a lot of air and water for plants to take root in. The small size allows for quick drainage and space for air and oxygen for roots.

How To Use Grow Cubes

Grow Cubes require soaking in pH adjusted water for several hours before being shake or squeezed to have the excess drained out of them. Once this is done, plants and cuttings can be placed into the Grow Cubes and the system can be run.

How do you use Grow Cubes?

To use Grow Cubes, simply soak them in water or a nutrient solution until fully saturated, then place seeds or cuttings into the cubes. Position the cubes in a tray or hydroponic system, ensuring they stay moist for optimal root development and plant growth.

How do you germinate seeds in Grow Cubes?

To germinate seeds in Grow Cubes, place the seeds directly into the pre-soaked cubes, then keep them in a warm, well-lit area. Maintain moisture by misting or adding water as needed, and seedlings should emerge within a few days, depending on the seed type.

Are Grow Cubes reusable?

How do Grow Cubes benefit hydroponic gardening?

Can Grow Cubes be used in soil-based gardening?

Yes, Grow Cubes can be used in soil-based gardening as a starter medium for seeds or cuttings. Once roots are established, the cubes can be transplanted directly into soil, helping plants transition smoothly from a controlled environment to the garden.
