An automated smart hydroponic farming pod is designed to grow leafy greens indoors. The system monitors environmental conditions to ensure optimal growth. It automatically adjusts the pH of the water by dispensing acidic or alkaline solutions, controls the water temperature, and regulates the intensity of the LED growth lamps based on the growth stage. It displays real-time nutrient levels and ambient humidity on an integrated LCD panel, and sends push notifications to a mobile application if the water reservoir level drops below a critical threshold.
