Rockwool cubes are the preferred growing medium for hydroponic systems. Rockwool doesn't dry out easily and are great at retaining water. At the same time - their porous nature provide space for your plant's roots to grow within the cube. These properties make it hard to over-water or under-water your seedlings, making them easy to use for experts and novices alike. Our rockwool cubes have planting holes to plant your seeds. They are also pre-scored, making them easy to pull apart. At "1.75" x 1.75" they are designed to fit snugly at the bottom of your net pot without the need for added pebbles. They will provide a sturdy and solid foundation for your plants to grow.
