Rockwool

Rockwool is a high-performance growing medium made from molten rock, designed for hydroponic setups. It’s known for its ability to retain moisture while allowing for great air flow to the roots. Perfect for seedlings, propagation, and hydroponic systems, rockwool comes in a variety of sizes and forms, like cubes and slabs, so you can customize it to your growing needs. It’s especially great for starting plants and providing a stable, sterile environment for root development.
