Frequently Asked Questions

What is the best way to prepare rock wool cubes for use?

Typically, rock wool cubes should be soaked in pH-adjusted water (usually around pH 5.5) for a few hours before planting to ensure they are adequately hydrated and buffered.

Can these rock wool cubes be used in soil gardens?

Yes, while optimized for hydroponics, these cubes can also be used in soil-based gardening for starting seeds and transplanting, offering a controlled environment for early root development.

How long can seeds or cuttings remain in these cubes?

Seeds and cuttings can stay in these cubes for several weeks, or until their roots are well-established and ready to be transplanted into a larger growing medium or system.

What is the typical pH range of rock wool cubes after buffering?

After proper buffering, rock wool cubes generally maintain a pH close to neutral, around 5.5 to 6.0, which is ideal for nutrient absorption by most plants.

Are these rock wool cubes reusable?

Rock wool cubes are generally considered a single-use medium for propagation. Once a plant has outgrown them and been transplanted, the cubes are typically discarded or composted.
