Grodan rock wool cube (15x15x13,5 cm)

The Grodan stone wool cube are intended to make a hydroponic cultivation in rock wool from any type of plant.

Thanks to their great aeration, they allow the development of roots at great speed, which is reflected in rapid growth and development of plants.

Typically, stonewool cubes are laid out on a grow table that channels excess water, or in a slab pot.

Rockwool plugs are a hydroponic growing medium whose main advantage is its great aeration in the root zone.

The stone wool cube is a growing medium that retains water well but needs frequent watering when the plants are large.

For this reason, we recommend using a drip irrigation system such as the line floraflex.

Very interesting are the Floraflex Caps that allow you to water the rockwool blocks evenly and prevent the appearance of fungus on the top of the rockwool cube.

The measurements of the Grodan stone wool cubes are:

• 15 x 15 x 13,5 cm.

Growlet tip:

Having such a small surface, we recommend that you use meshes for SCROG to keep plants upright.

Normally the weight of the buds will knock them over, but with the meshes you will avoid this.
