Rockwool or rockwool cube for hydroponic cultivation, the perfect substrate for this indoor cultivation technique.
Each block has a density , flexibility and virtually identical robustness, ensuring an even distribution of water, EC and pH to produce a uniform and high quality system. This promotes the development of a strong root system during propagation.
The uniform distribution and vertical structure of the fibers results in the same resistance for each root, thus ensuring that the roots are distributed evenly throughout the block.
