Rockwool Grow Cubes |
 |
||||||||||
Grow Cubes are small, loose 1/2" cubes of
stonewool. Advantages are better aeration, maximum drainage so that you can
hardly ever over-water your plant, easy mixing with other loose media (such
as expanded clay rocks or coconut fiber), lightweight and much cleaner than
pot-based media. The properties of Grow Cubes
make it like a 50/50 mix of absorbent to repellant stonewool.
