Rockwool cubes are the ideal growing medium for hydroponic systems. Known for their excellent water retention, rockwool doesn't dry out easily, and its porous structure allows plant roots to grow freely. These qualities make it difficult to over-water or under-water seedlings, making rockwool cubes suitable for both beginners and experts. Our rockwool cubes come with planting holes for seeds and are pre-scored for easy separation. Measuring 1.75" x 1.75", they fit perfectly at the bottom of your net pot, providing a stable foundation for healthy plant growth without needing extra pebbles. They will provide a sturdy and solid foundation for your plants to grow.

FAQ
Rockwool cubes retain water well and allow roots to grow freely, making them perfect for hydroponics.
Rockwool's water retention and porous nature will increase your margin of error, for over-watering or under-watering. But it's not idiot-proof.

Awesome Cubes
These cubes originally came with my ALTO Garden tower. When planting my second season I bought some other cubes but they were smaller and didn't work as well. So bought these again and they are terrific. Best way I can describe them is "hearty." They are fuller and bigger and fit snug at the bottom of the net pot so my plants don't wobble around. Great cubes will stick to these from now on.
