FAQS on hydroponic clay balls

Q: What are hydroponic clay balls used for?

A: Hydroponic clay balls, also known as expanded clay pebbles, provide a sterile, pH-neutral growing medium. They support root systems, improve aeration, and retain moisture in hydroponic systems.

Q: How do hydroponic expanded clay balls improve plant growth?

A: Their porous structure ensures optimal oxygen flow to roots and prevents waterlogging. This promotes healthier root development and nutrient absorption in hydroponic setups.

Q: Can hydroponic clay balls be reused?

A: Yes, rinse and sterilize them between cycles to remove debris and pathogens. Proper maintenance ensures longevity and sustainability in hydroponic gardening.

Q: Do hydroponic expanded clay balls require pre-treatment before use?

A: Rinse them thoroughly to eliminate dust and soak for 24 hours to balance pH. This prepares the clay balls for immediate use in hydroponic systems.

Q: Are hydroponic clay balls suitable for all plants?

A: They work well for most hydroponic plants, especially those needing good drainage. However, moisture-sensitive species may require mixed substrates for optimal growth.
