Product Description
Grofine GF-MC 10 rock wool micro cubes are a loose, inorganic horticultural growing medium made from nominal 10 x 10 x 10 mm hydrophilic rock wool. Its stable fiber structure supports reliable initial wetting and rewetting, manageable moisture distribution and physical air spaces between cubes.
It can be used as a stand-alone growing medium or incorporated into customized substrate blends for orchids and selected high-value specialty crops.

Target Applications
Orchids, including Paphiopedilum and selected nursery-stage orchid crops; Anthurium and other high-value specialty plants subject to crop trials.
Key Benefits
RELIABLE WETTING AND REWETTING
Stable hydrophilic treatment allows the cubes to absorb irrigation solution readily and rewet consistently after drying.
MANAGEABLE WATER AIR BALANCE
Porous fibers retain moisture inside each cube, while physical gaps between cubes help maintain air space throughout the container.
STABLE ROOT ZONE STRUCTURE
The inorganic fibrous structure maintains its physical form without decomposing like organic substrate components.
ROOT PENETRATION
The porous fiber structure allows developing roots to enter and grow through the cubes.
FLEXIBLE APPLICATION
Suitable for stand-alone use or incorporation into customized substrate blends.
General Use Guidance
- Pre-wet the cubes evenly with a crop-appropriate nutrient solution before potting.
- Fill containers evenly without excessive compression.
- Adjust irrigation according to crop, pot size, climate, water quality and substrate composition.
- Conduct a small commercial trial before large-scale conversion from bark or other media.
Important Notes
- Rock wool is an inert growing medium and does not supply a complete nutrient program.Irrigation practices used for bark or coarse organic media may not transfer directly to rock wool.
- Repotting should be determined by root volume, salt accumulation, plant health and sanitation requirements.
