Description

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.

Dimensions: 53 cm (L) x 31 cm (W) x 3 cm (H).

  • The tray has 77 Rockwool Plugs in it.
  • Square Rockwool Plugs (36 mm x 36 mm (Top) x 40 mm (H)) are sold INDIVIDUALLY as well.

Rockwool  has a pH of roughly 7.8. Please see ‘Preparation’ below.

Preparation

Items you will need:

  • Rockwool plug
  • Bowl or other container that holds water
  • pH Balancing Chemicals (pH Down, pH Up)
  • Seeds

Rockwool Cubes have a pH of roughly 7.8. This is pretty alkaline, yet our plants prefer to grow in a slightly more acidic environment (between 5.5 – 6.5). In order to prepare our Rockwell cubes for the seeds, we need to soak them in some pH adjusted water, that way they have everything the seeds need to germinate and sprout; water and a slightly acidic environment.
