Rock wool block: Substrate for cuttings or seeds

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.

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 available measures of rock wool plug are:

• 4 x 4 x 4 cm.
• 7,5 x 7,5 x 6 cm.

Growlet tip:

Remember to hydrate for 24 hours. rock wool at a pH of 5,5.

Then drain them and water them with pH 6.

You already have the plugs ready to put your plants.
