Grodan Gro-Block Improved Mini-Block, 1.5" - Case of 2250

The Grodan Delta design forms the foundation for uniform and perfectly controllable propagation of plants, a prerequisite for powerful and vigorous plant growth. The variation in small and large pores throughout each block ensures that plant roots are always supplied with an optimal balance of air and water. Moreover, the water content of each block can be controlled with precision, and the efficient pattern of the pores ensures uniform distribution of water and nutrients throughout the block. This offers excellent control over both the nutrient solution and the pH, promoting the development of a robust root system during propagation.
