In hydroponics, plants receive nutrients directly from a water-based solution. pH affects how well plants can absorb these nutrients. If the pH is too high (alkaline) or too low (acidic), certain nutrients become chemically unavailable, leading to deficiencies even if the nutrients are present. To adjust the pH, hydroponic farmers have to use pH up solution (commonly potassium hydroxide or potassium carbonate) or pH down solution (commonly phosphoric or nitric acid), which adds cost, increases safety risks and utilises resources like time, manpower and storage space.

This innovation combines Electrolysed Water (EW) with an Internet of Things (IoT) system to autonomously adjust pH to improve vegetable health, optimise plant growth, and reduce algae without the use of chemicals. The solution features a modular chamber setup, precise EW control, and real-time environmental monitoring. The technology addresses the common challenges of uneven plant growth, algae outbreaks, and chemical handling in urban agriculture.
