Cultivating a homogeneous batch of plants forms the basis for a successful
crop. Climate conditions and the materials used are crucial factors in the
growth process. Grodan is very aware that the substrate block is crucial in
this process. Accordingly, the new Grodan Delta block is uniform throughout.
It is robust and handles excellently during both manual and automatic
processing. This results in even water distribution across the depth and
ensures optimum control of the air/water balance and the nutrient solution
(EC). In addition, with Grodan Delta, the root growth is spread throughout the
entire block.

In summary, Grodan Delta is the ideal basis for the perfect growth.


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 the water is distributed uniformly throughout,
so reliable and vigorous plant growth is guaranteed.

Uniform WC and EC Distribution – 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.

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 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.

Grodan Delta forms the foundation for uniform and perfectly controllable
propagation of plants – an absolute condition required for vigorous and
healthy plant growth. Each block has an identical density, flexibility and
sturdiness, which guarantees even distribution of the WC, EC and pH. The
result is a uniform and high quality plant.

Grodan Delta is the best block for essential properties such as firmness and
saturation. These qualities make Grodan Delta ideally suited for propagators
who want to secure the success of their processes.
