Horticubes® Growing Medium
offers a versatile system that has
multiple applications for those
crops that require high water
usage. Hydroponic seed
germination and foliage plant
propagation are good examples.
This medium is designed to drain
off excess water from the base of
the cutting or seed, yet provide for
the proper balance of air/water
needed for good root
development. Horticubes are
commonly used for hydroponic
lettuce, tomato, herb, and onion
seed germination.
