Grodan Rockwool is a mineral wool made from molten basalt and limestone rock that is spun into cotton-candy like fibres and then compressed into cubes, blocks or slabs.  

Being made from natural rock, Grodan is a mineral based product used in hydroponic growing applications.
The WCB or Wrapped Crop Box Slab by GRODAN is designed to suit a 45litre crop box crate.

 They are called wrapped as they are supplied as individually plastic wrapped slabs and the wrapping is UV resistant.

Featuring a predominantly horizontal fibre structure which allows for slow water movement through fibres, these slabs are best used where less frequent watering is required or in hot climates.

These slabs are an ideal multi-year (2 year) slab.
To use, cut a hole or holes in the plastic to the size of the rockwool cube that you want to use with the slab.  

Fill the slab with water to moisten the rockwool, then flip the slab over and cut drainage slits in the bottom of the plastic across the width.  

Flip the slab back over and place your planted growing cubes on the previously cut-out holes in the top side of the slab.  

The plant roots will then grow through to the slab over time.

GRODAN Delta Benefits1. Effortless start up of propagation

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

2. Uniform WC and EC distribution

Based on the Delta Technology, the structure of the block and water distribution throughout the substrate have been improved. Newly transplanted plants will benefit thanks to the ready availability of water and the balanced nutrient solution (EC), encouraging the roots to penetrate deeply into the blocks.

3. Easy WC management

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 be restored to the desired level, for instance 80%. Thanks to the variations in the small and large pores, the roots are always guaranteed a sufficient supply of air and water.

4. 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 ready availability of water and EC, encouraging the roots to penetrate deeply into the slabs

5. Greater firmness for better handling

As mechanisation has been increasingly introduced into the propagation process over the years, the blocks must be able to withstand handling better 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 transport from the propagator to the grower.
