Grodan Stonewool / Rockwool - 4 X 4 X 4cm - Great For Clones, Seedlings And Cuttings

Rockwool cubes are a must-have for anyone looking to raise seedlings and cuttings in their hydroponic setup. They are ideal for hydroponic gardening because of their great moisture and oxygen retention without ever impeding the development of roots.

These wrapped cubes are the ideal size for starting seeds or propagating cuttings, as well as being adaptable to almost any growing setup. Once roots emerge you will need to plant them into larger Grodan Transplanting Cubes or another growing medium.

Grodan Rock Wool Cubes Specifications:

• Wrapped Cube
• Cube Size: 40MM x 40MM x 40MM
• With Holes

How to use:

• Wash the cubes with warm pH adjusted water set at 5.5, keeping moist but not saturated once seeds/cuttings have been planted.
• Over watering can inhibit root development as well as making the plant more susceptible to root rot.
