Best match for small Hydroponic systems
The perfect medium for mid-sized plants grown in a hydroponics system. Root systems love rockwool cubes, and if used with Grodan seedling cubes (1-1/2" x 1-1/2 " ) the combo cannot be beaten. Convenience, economy, and practicality are all combined within the Grodan Rockwool cubes.
