Grow Media (Rockwool, Clay Pebbles, Coco etc)

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 (1") cubes are ideal for starting seedlings / cuttings, and then can be transferred into 7.5cm (3") cubes. Afterwards, 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 repellent 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, and 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.

When using rockwool to raise or start seedlings, make a stock solution using your grow nutrient or similar, to a TDS / CF reading of 10-12 then pH adjust that stock solution down to 5.5 pH. Decant this solution into a bottle so you can feed this to the rockwool as and when needed. Shake bottle well before sprinkling. Do no over soak or let rockwool sit in a puddle of nutrient.
