Our Recommendations for Rockwool Growing Media

Growing can be full of challenges no matter which phase of a plant’s growth we are in the midst of tackling. Many of us find challenges from the very beginning. Plant propagation is the start of growing new plants. It is done by starting seeds or rooting cuttings. It is typically done by taking samples from a single parent plant. The process is simply done yet a delicate process that demands an accurate following of its considered steps. The overwhelming choice of growing medium for propagation is rockwool. This remarkable medium is made from crushed basaltic rock that has been reduced to the finest fibres.

Here at Hyjo we understand that the craft of growing is not as simple as picking up any old tools. Getting hold of high calibre rockwool is only advisable and the industry standard for successful propagation. We have an extensive range of rockwool products available for you online and in our store.
