Hydroponically grown sweet potatoes may be toxic. Sweet potatoes easily produce toxic substances in water, especially in high-temperature and humid environments in summer, and are easily invaded by bacteria, viruses and other harmful substances, affecting human health. In addition, the nutrient solution used in hydroponic sweet potatoes may contain heavy metals such as copper and zinc. If used improperly, it may also have an impact on human health.

In general, hydroponic sweet potatoes may contain toxicity and pose a potential threat to human health. Therefore, when growing hydroponic sweet potatoes at home, attention should be paid to standardized management to reduce potential risks.
