Grodan Miniblock
Start from seed or cuttings easily and successfully
Grodan rockwool mini-blocks are ideal for seed and cuttings propagation. Grodan mini blocks are made of volcanic rock, are 100% sterile and can be used in soil and coco as well as in hydroponic systems.
Grodan mini-blocks should be soaked in water with a pH of 5.5 before rooting. After soaking, do not squeeze to avoid damaging the internal structure. Grodan mini blocks are individually wrapped in plastic to prevent algae growth.
Grodan Mini Blocks are the ideal medium for successful cultivation. After rooting, they also fit perfectly into the Grodan Delta block, 7.5x7.5x6.5 cm, ø 40 mm.
