What would happen if you heated up a rock to the point where it becomes liquid and decided to spin it like fairy floss? These rock wool cubes are exactly that, and the outcome? A super light, incredibly absorbent growing medium that maintains perfect aeration and moisture levels at all stages of plant growth.
To use these simply soak them in water for 10 minutes before planting seeds. You can use them in your EcoKitchen Smart garden, or on their own.
Rockwool is the ideal growth medium for most types of seeds, cuttings or even transplaints.
Dimensions of each cube: 4cm (h) x 2cm (w) x 2cm (l)
