Hydroponics Water Quality Monitoring & Nutrient Control System | GAIMC

The Foundation of Successful Hydroponic Cultivation

Hydroponics is a new type of soilless plant cultivation method, also known as nutrient solution culture. Its core is to directly immerse the roots of plants in nutrient solution, and use nutrient solution instead of soil to provide plants with water, nutrients, oxygen and other growth factors, so that plants can grow normally. Therefore, hydroponic water quality monitoring is the key to the success of hydroponics.

Four Essential Water Quality Parameters for Hydroponics

Maintaining precise control over these four key parameters is crucial for creating the ideal growing environment and maximizing plant health and yield.

1. pH Level

The pH of the nutrient solution should be appropriate to facilitate the absorption and utilization of nutrients by plants. The pH should generally be controlled at 6-6.9 pH.

2. Electrical Conductivity (EC)

The conductivity reflects the nutrient concentration in the nutrient solution. Appropriate conductivity can ensure proper nutrient supply and promote healthy growth and development of plants. Generally, the conductivity should be controlled at 2000-3000us/cm.

3. Dissolved Oxygen (DO)

Plants need to absorb oxygen for normal growth and metabolism, and the water quality of the nutrient solution is also related to dissolved oxygen. Generally, dissolved oxygen is controlled at 4-5 mg/L.

4. Water Temperature

The appropriate temperature range can promote the root system of plants to absorb nutrients, improve nutrient utilization, accelerate growth, and increase yield and quality. Generally, the temperature needs to be controlled at 18-25℃.

Smart Hydroponics Monitoring & Automated Management System

GAIMC's integrated system continuously monitors critical parameters like temperature, pH, EC, and dissolved oxygen in the nutrient solution reservoir. Real-time data is transmitted to a central platform via RS485 or wireless IoT modules, enabling remote monitoring and control. This allows for the automated dosing of nutrients and pH adjusters, ensuring the nutrient solution balance is always optimized for plant uptake and development. By maintaining the ideal growing conditions on the cultivation bed, the system not only reduces labor and resource costs but also guarantees that plants remain in their peak state of growth and health, leading to consistently higher yields and superior quality.
