Catalogue: Section 4: Grow Media

Growing media is an essential part of any hydroponic growing system. Simply put, growing media is a soil substitute. There are many types of grow media available, each offering different advantages. These media are all inert, sterile substrates that have excellent aeration properties. Rockwool 2.5cm (one inch) cubes are ideal for starting seedlings/cuttings, and then can be transferred into 7.5cm (three inch) cubes. Afterwards, the growing cubes are either planted onto rockwool slabs or into your hydroponic system or other substrate like GreenMix which is a mixture of water retentive and water repellant rockwool. This gives better drainage. Clay pebbles are by far the most popular potting on hydroponic medium and are used in flood and drain, drip irrigation, passive systems, even some NFT systems. This medium provides excellent aeration, superb pH stability and can be re-used. It can also be mixed with soil to improve aeration and drainage.

Rockwool Cubes

Grodan Cubes.

These are ideal for transferring and growing seedlings, and cuttings grown in SBS cubes. At this point, the growing cubes are planted on into NFT systems or Grodan Rockwool Slabs. The wrapped cubes come in two sizes: small aperture (for small SBS) or larger aperture (for large SBS). Please specify when placing your order.
