Great capacity for absorbing nutrient solutions while retaining plenty of oxygen for rapid plant growth, ensuring even distribution of roots. Each cube is individually wrapped in UV resistant plastic on 4 sides to hold the block together. The base of the growing blocks are grooved to promote drainage.
