GRODAN STONEWOOL CULTIVATION BLOCK
From €0,65
Grodan growing blocks are the key to growing seeds and young plants. Water distribution has been improved, resulting in more efficient use of the entire substrate volume. The continuous root growth in the plug ensures a healthier and more vital plant throughout the growing season. These advantages lead to higher yields, better fruit quality and a lower susceptibility of the plants to diseases.
