How Do I Use Rockwool Cubes With SBS Trays?

Before you use rockwool, it needs to be soaked in a pH corrected water and weak nutrient solution. Ensure the solution is corrected to pH 5.5. You can also pre-soak the cubes in a ready pH corrected product, that's specifically designed for use on young plants, such as: formulex.

Garden tip: It's also a great idea to add some beneficial microbes to help stimulate a strong response from rooting cuttings and seedlings.

After you soak the rockwool cubes, ensure you drain any excess solution. The cubes should not be soaking wet. Rockwool is extremely absorbent, and roots need access to air for healthy growth.

Garden tip: To ensure you remove enough water/nutrient solution, before use, flick out cubes that are too wet, displacing water with air.

Once you have established a good root system in the SBS cubes, you can transplant your plants into 3" or 4" blocks for their vegetative and flowering periods.

Rockwool cubes are suited to NFT, Flood and Drain, and Bubbler type systems, you can even plant them directly into soil or Coco coir.

If you look after your plant's roots, right from the start, you're more likely to have healthy, productive plants.
