GRODAN planting cube 36x36x40mm in planters of 77pcs - BOX 18 plantersCode: 3836
Product detailed description
Grodan planting block is a practical and recyclable growing medium.
It is made of basalt wool and calcium by melting in an oven at 1500 ° C.
This process creates "stone" lava, which is further processed into thin fibers and then pressed into the desired shape.
Thanks to this process, the growing medium is completely sterile.
Mineral felt (rockwool) has excellent absorption properties and a balanced ratio of water and air.
Thanks to its properties, Grodan planting cubes can be used repeatedly and will ensure the unique development of the root system of the cultivated plant.
Grodan planting cube measuring 3,6 x 3,6 x 4 cm is predestined for sowing seeds or for rooting fresh cuttings.
BEFORE using, ALWAYS pour (soak) all Grodan products sufficiently in lukewarm water (we recommend water at 25 ° C).
The pH of the water must be 5.8-6.
