Product detailed description
Grodan planting cube is a practical and recyclable growing medium.
It is made from basalt wool and calcium by melting in a furnace at a temperature of 1500 °C.
This process creates "stone" lava, which is further processed into thin fibers and then pressed into the desired shape.
This process makes the growing medium completely sterile.
Rockwool has excellent absorption properties and a balanced ratio of water and air.
The Grodan planting cube can be used repeatedly thanks to its properties 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 intended for sowing seeds or for rooting fresh cuttings.
For easier handling, each Grodan planting cube is supplied in its own plastic planter.
Before use, ALWAYS remember to pour (soak) enough rockwool in lukewarm water (we recommend water at a temperature of 25 degrees), starting with planting cubes and ending with mats.
The water must have a pH adjusted to 5.8 - 6.
1 plate - 77 pcs of cubes in planters.
