Rockwool Grodan Delta


– L 14,5 x 14,5 x 14,5 cm

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.
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 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 water.

WHAT IS PRECISION GROWING? It is the most efficient and effective form of growing focused on achieving maximum results with a minimum of input materials. Growing costs decrease, crop yield and quality increase. All GRODAN substrate solutions are aimed at doing more with less, with respect for people and the planet.
