Protect Roots
Sponges provide additional protection to roots, helping them grow stronger and healthier. By creating a stable and well-ventilated environment, sponges reduce stress on roots, facilitating their development. In addition, sponges prevent roots from rotting by preventing excessive accumulation of water, while providing a protective barrier against temperature fluctuations and physical shocks.
