Grodan growing cube small 75x75x65mm, without hole

Product detailed description

Grodan planting cube, rockwool - basalt wool of the highest quality, great absorption capacity (balanced ratio of water and air), dimensions: 75 x 75 x 65 mm without hole

Grodan planting cube is a practical and recyclable growing cube 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 seeding cube measuring 7.5 x 7.5 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), starting with planting cubes and ending with mats.< br />The water must have a pH adjusted to 5.8 - 6.
