How To Use

Pre-soak the grow cubes in pH-adjusted water (typically between pH 5.5 – 6.0) until fully saturated.

Place seeds or cuttings into the pre-formed holes in each cube.

Arrange the trays in your growing area with appropriate lighting and environmental conditions.

Maintain consistent moisture by monitoring the cubes and watering as needed to avoid drying out or oversaturation.

Once roots are established, transplant the cubes onto Grodan blocks, slabs, or into your preferred hydroponic or soil-based system.
