Rockwool can hold large quantities of water and air that aid root growth and nutrient uptake in hydroponics; the fibrous nature also provides a good mechanical structure to hold the plant stable. It is used primarily for drip hydroponic systems.
Rockwool is made by melting a combination of rock and sand and then spinning the mixture to make fibers which are formed into different shapes and sizes.
- Tray Dimensions: 53 cm (L) x 31 cm (W) x 3 cm (H).
- The tray has 77 Rockwool Plugs in it.
Square Rockwool Plugs sold INDIVIDUALLY as well.
