Uses for Rockwool Cubes

Seed Starters – Rockwool cubes are one of the best seed starting mediums. All you have to do is keep your cubes moist and the near perfect air

to water ratio will create the perfect seed-sprouting environment. Hydroponic and soil gardeners alike can utilize the benefits of Rockwool as a seed starter. 

Cutting/Clone Propagation – Rockwool is also very popular for the propagation of roots in cuttings. When used along with a cloning gel, Rockwool

provides the proper environment for new roots to sprout. You’ll greatly improve your ability to clone mints, berry bushes, fruit trees and even medical plants.

The process is as simple as taking the cutting, dipping into cloning gel and then placing it into the moist Rockwool for incubation.

Full Life Cycle Growing – Hydroponic gardeners can also benefit from the larger Rockwool cubes. These large cubes can provide a perfect full lifecycle growing medium for plants.

Many hydroponic gardeners prefer using Rockwool because they bypass the messy growing mediums such as expanded clay and Coconut fiber.

Advantages of Rockwool cubes for hydroponics:

Retains Water: One quality of rockwool that has found great favor among commefcial growers is its water-giving abilities. Since rockwool will resily give up

water to the roots, even when it is almost dry, growers can allow more of the pore space in rockwool for air, while still maintaining a satisfactory supply of

nutrient solution to the roots. 

Holds Air: Rockwool holds at least 18% air at all times, which supplies the root zone with plenty of oxygen.

Comes in a variety of sizes and shapes: 3*3*4cm, 4*4*4cm cubes desinged for use in propagation, 100*20*7cm, 100*20*7.5cm slabs capable of holding

the root systems of huge plants.
