Raising seeds and cuttings easily and successfully
These mini blocks made of rock wool are ideal for growing from seeds or for cuttings. Made from volcanic stone, the Grodan mini blocks are 100% germ-freeand can subsequently be used in soil and coco, as well as in hydroponic systems.
Before rooting, the Grodan mini blocks must be soaked in water with a ph value of 5.5. Afterwards, the blocks should not be squeezed out to protect the internal structure from damage. To protect against algae growth, the Grodan mini blocks are individually wrapped with plastic film.
Grodan mini blocks are the ideal medium for successful growing. Once rooted, they also fit perfectly into the Grodan Delta culture block, 7.5x7.5x6.5 cm, ø 40 mm.
