Grodan Classic MY is ideal for multi-year use and optimally suited for tomato and cucumber cultivation.

The Grodan Classic Multi Year stone wool slab for vegetable crops is based on NG2.0 technology, and is perfect for use for several growing seasons. The hydrophilic fiber structure enables the slab to absorb water more easily. The wide control range and evenly distributed water content and EC (in the slab and between the slabs mutually) results in a healthier root system and extra vigour. The Grodan Classic Multi Year slab is the ideal solution for critical growers who want to maximise their crop performance season after season.

Key benefits

• Wide control range
• Perfect root development
• Uniform WC and EC distribution

Product specifications

• Multi-year slab
• Extra firm thanks to special fiber structure
• Inert, hydrophilic fibers

Product characteristics

The wide control makes the slab extremely flexible in its range of application. And thanks to the special fiber structure, the slab is also extra firm, for solid performance during multiple production cycles.

Block-slab combination

Grodan Classic MY, together with the Plantop propagation block, ensures a stable plant balance for the entire growing season.

NG2.0 Technology

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.

Perfect for Precision Growing

Grodan GT Master is absolutely ideal for tomato, cucumber or eggplant growers who want to realise a generative or vegetative crop response through targeted control.

The Grodan GT Master with NG2.0 technology offers a unique fiber structure that encourages plants to completely penetrate the slab with a finely branching root system. Combined with the outstanding physical properties, such as rapid resaturation and perfect steerability based on WC and EC, crops have the ideal conditions for a maximum performance – even during periods of high solar irradiance. These properties make GT Master perfectly suitable for Precision Growing: controlled and considered management of the climate, crops and root zone environment – mutually synchronised to maximise crop performance – while making efficient use of water and nutrients.

Key benefits

• Optimal steering range
• Optimal irrigation efficiency
• Uniform crop development

Product specifications

• Single-year slab
• Unique upper layer with higher fiber density
• Inert open, hydrophilic fibers

Product characteristics 

The Grodan GT Master consists of a unique, dual-layer slab structure. This combination of a dual-density ‘solid’ upper layer and an ‘airy’ lower layer ensures even WC and EC distribution in the slab. This in turn leads to a uniform distribution of roots in the slab, which increases the absorption capacity of the plants.

Block-slab combination

The combination of the GT Master and the Plantop block offers growers complete control of the plant balance throughout the entire growing season.
