Grodan Classic Slab (Unwrapped)

Grodan Classic is an extremely reliable substrate and ideal for tomato and cucumber cultivation.
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.
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.

Features

• • Reliable control range:

Grodan Delta is the perfect block for propagating young plants under a wide range of propagating conditions. The block is easy to saturate and the water is distributed uniformly throughout, so reliable and vigorous plant growth is guaranteed.

• • Rapid EC Refreshment:

Based on the Delta technology, the structure of the block and the water distribution throughout the substrate have been improved. Newly transplanted plants will benefit thanks to the readily available water and the balanced nutrient solution (EC), which encourages the roots to penetrate deeply into the blocks.

• • Horizontal root development:

The water content levels can be easily managed between 55% and 80%. This applies equally to low and high water content levels. If the moisture content level threatens to drop too low it can be simply restored to the desired level (for example back up to 80%). Thanks to the variations in the small and large pores, the roots are always guaranteed to have a sufficient supply of air and water.

• • Excellent root growth throughout the block:

The Delta technology ensures uniform distribution of water and nutrients throughout the block. Newly transplanted plants will benefit thanks to the readily available water and EC, which encourages the roots to penetrate deeply into the slabs.

• • Greater firmness for better handling:

As mechanisation has been increasingly introduced into the propagation process over the years the blocks must be able to better withstand handling during propagation. The stable firmness of Grodan Delta becomes particularly important when the blocks are placed, spaced and picked up several times during propagation. An added advantage is greater protection for the roots during transportation from the propagator to the grower. Grodan Delta is a solid base for top production.
