Adjust the pH value to approximately 5.8±0.3 to meet the growth requirements of rice.

Regularly replace the nutrient solution; for small water bodies, replace every 3-5 days.

Please note that these formulations and methods may need to be adjusted according to the specific hydroponic system and environmental conditions. Additionally, the water temperature should be maintained at around 25 degrees Celsius, and the root system should be shielded from light to prevent algal growth and oxygen consumption by root respiration.
