Grow Cubes are small 1/2” cubes of stonewool.
Made from natural melted rocks blown into mineral fibers, Grodan stonewool (generically known as rockwool) has become the preferred choice of soil-less growing worldwide.
Using their exclusive Delta® Technology for improved fiber structure and layering, they create perfectly uniform products which are both chemically and biologically inert. This provides a clean medium for growing high quality vegetables, fruits, and vibrant flowers.
There are several advantages to using this loose medium:
• Better aeration due to how the cubes stack on top of each other
• Maximum drainage from each cube so that you can hardly ever overwater your plant
• Easily mixes with other loose media (such as expanded clay rocks or CocoCan™ Gro-Mix)
• Lightweight
• Much cleaner than a peat-based medium, but with a better growth rate
The properties of Grow Cubes make it like a 50/50 mix of absorbent to repellent stonewool.
Grodan Grow Cubes are sold by the case in either 1 cubic foot or 2 cubic feet bags.
A case of Medium bags (1 cubic foot) contains 6 bags.
A case of Large bags (2 cubic foot) contains 3 bags.
