Rockwool

Rockwool is a versatile and reliable growing medium that has long been a favourite of hydroponic growers. Made from spun volcanic rock, it provides an ideal balance of moisture retention and aeration, giving roots constant access to water, oxygen, and nutrients. Available in cubes, blocks, and slabs, Rockwool is perfect for propagation, transplanting, and full hydroponic systems, offering consistency and control at every stage of plant growth.
