Grodan Rockwool Grow Cubes
Ideal for those who like to grow in a pot passively or in one of our active systems for better results. They are a loose substrate made of stonewool, not only are they lightweight but they also provide large air spaces since there is always open spaces amongst the cubes. They can also be combined with clay pebbles to give a tailor made compost combining the best water/drainage characteristics of each product.
Available in: 10 Litres, 20 Litres & 90 Litres
