Description

Rockwool slabs are wrapped and sealed in plastic. Most people will start their plants in Rockwool cubes and then transplant them to the slab. To transplant a Rockwool cube to the slab, simply cut an X that is the same size as the cube, in the plastic on top of the slab. You then lift the plastic tabs and set the cube on top of the slab. You may want to pin the cube temporarily with a plastic spike until the roots grow down into the slab.

Dimensions: 1m x 20cm x 7cm

PLEASE NOTE:
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.
