Grodan planting cube 36x36x40mm with hole without planter, 1pc

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.
The Grodan planting cube with dimensions of 3.6 x 3.6 x 6.5 cm is intended for sowing seeds or for rooting fresh cuttings.

Before use, ALWAYS remember to pour (soak) enough rockwool in lukewarm water (we recommend water at a temperature of 25 degrees).

br />The water must have a pH adjusted to 5.8 - 6.
