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.

the root systems of huge plants.
