GRODAN - MINI-BLOCKS ROCK WOOL CUBES | 4x4x4h cm

Grodan Mini-Blocks are small rockwool cubes measuring 4x4x4h cm.

Grodan Mini-Blocks can be placed in a tray (flat) without a stand for easy germination of seeds and propagation of cuttings. They are individually packed to minimise algae growth. Each block has virtually identical density, flexibility and strength, ensuring an even distribution of water, EC and pH to produce a uniform, high-quality plant.This promotes the development of a strong root system during propagation. The uniform distribution and vertical fibre structure results in the same strength for each root, ensuring that roots are evenly distributed throughout the block.

Transplanting
Transplanting can be done on any loose substrate such as Grow-Cubes, or placed directly on a larger Grow-Block. These cubes are popular for hydroponic plant production and are indispensable for germination in this type of crop.
