The Grodan Classic stone wool slab for vegetable crops is based on NG2.0 technology. Grodan Classic is the ideal solution for growers looking for a reliable substrate that allows simple irrigation and ready drainage. Grodan Classic offers quick EC refreshment and promotes good root development. This slab guarantees a good yield with highly consistent fruit quality.
- Reliable control range
- Rapid EC refreshment
- Horizontal root development
- Single-year slab
- Horizontal fiber structure
- Stable WC and EC distribution through the entire slab
The fiber structure of the Grodan Classic makes it the ideal slab for frequent irrigation. This structure also facilitates ready drainage, so the EC level is easy to adjust and control.
Grodan Classic, together with the Plantop propagation block, ensures a stable plant balance for the entire growing season.
NG2.0 is the successor of the Next Generation Technology and adds new benefits to the existing advantages. Water distribution is even more uniform and the crop utilises the total substrate volume better. Continual new growth of roots in both the block and the slab results in a healthier and more vigorous crop throughout the whole growing season. These benefits translate into higher yields, improved fruit quality and reduce the sensitivity of the crop to diseases. The technology is available in plugs, blocks and slabs.
