Hydroponics is a modern cultivation technique that utilizes nutrient solutions instead of soil for crop production. Currently, challenges, such as high cost, high energy consumption, greenhouse gas emission, and significant wastewater generation are drawbacks that limit its scale up. On the other hand, bioelectrochemical systems have emerged as a sustainable technology that resolve some of the aforementioned drawbacks, albeit in other scenarios. Bioelectrochemical systems applications are well documented in desalination, metal recovery, energy generation, contamination remediation etc. This work conceptualizes the integration of bioelectrochemical systems and hydroponics with a view to improving the efficiency and sustainability of hydroponics. Firstly, a systematic review of the main challenges hindering hydroponic agriculture development is first carried out to identify possible entry points for the proposed systems integration. Thereafter, a conceptualized point-by-point resolution of the main identified challenges of hydroponic systems through bioelectrochemical systems integration is explored. Furthermore, the feasibility, stability, and scalability of the conceptualized hydroponic-bioelectrochemical integrated systems are discussed.

水培法是一种现代栽培技术，利用营养液代替土壤进行作物生产。目前，高成本、高能耗、温室气体排放和大量废水产生等挑战是限制其规模扩大的缺点。另一方面，生物电化学系统已经成为解决上述一些缺点的可持续技术，尽管在其他情况下。生物电化学系统应用在海水淡化、金属回收、能源生产、污染修复等方面得到了充分证明。这项工作概念化了生物电化学系统和水培法的整合，以提高效率和可持续性的水培法。首先，首先对阻碍水培农业发展的主要挑战进行系统审查，以确定拟议系统集成的可能切入点。此后，探索了通过生物电化学系统集成对水培系统的主要确定挑战进行概念化的逐点解决。此外，还讨论了概念化的水培-生物电化学集成系统的可行性、稳定性和可扩展性。
