Lighting: Thrives under bright illumination but can also survive under moderate lighting conditions. 0.25 watt per liter lighting is recommended.

Ideal pH conditions: Vallisneria asiatica prefers hard, alkaline water. It’s best to avoid softer acidic water for these aquatic plants because their growth rate slows down or they may even die. Recommended pH balance for the species would be between 6.5 to 7.6
