How to monitor and maintain the temperature in hydroponic method
UrbanKisaan uses an integrated ecosystem of proprietary hardware and AI-driven software to manage temperature. Their approach shifts away from manual tracking toward automated, "plug-and-grow" environmental control.
Here is how you can maintain and monitor temperature within their system:
1. Monitoring via "FarmOS"
UrbanKisaan's primary monitoring tool is FarmOS, a cloud-based operating system accessible via mobile and web.
IoT Sensors: Each unit (like the GrowRush) contains 8+ IoT sensors that track air temperature, water temperature, humidity, and nutrient levels (EC/pH).
Real-Time Dashboard: You can view live data feeds and historical trends on your dashboard.
24/7 Alerts: The system is programmed to flag "anomalies." If the temperature fluctuates outside of the pre-set crop protocol, you receive an instant notification on your phone.
URBI (Vision AI): They use mobile robots and cameras (URBI) to perform "phenotyping." These cameras can detect heat stress in plants (like wilting or tip burn) using infrared or visual cues before a standard thermometer might even register a problem.
Key Insight: UrbanKisaan claims their technology allows them to operate at 1/10th the CAPEX (capital expenditure) of global competitors by using low-cost, high-intelligence sensors rather than over-engineered industrial machinery.
1. How They Maintain Temperature
UrbanKisaan uses Controlled Environment Agriculture (CEA) to decouple the internal farm climate from the external weather.
Thermal Insulation & Modular Design: Their "GrowRush" units are modular, enclosed systems designed to be highly insulated. This allows them to maintain a stable internal "micro-climate" even in tropical or desert environments.
Precision HVAC & Airflow: They use specialized HVAC (Heating, Ventilation, and Air Conditioning) systems integrated with the racking. Instead of just cooling the whole room, they focus on airflow dynamics at the canopy level to prevent "heat pockets" created by grow lights.
Low-Heat LED Technology: Traditional lighting gets very hot. UrbanKisaan uses proprietary, PAR-optimized LEDs that are designed to produce minimal heat, reducing the energy needed to cool the space.
Passive Cooling (Greenhouses): In their greenhouse models, they employ passive cooling techniques like automated retractable shades and misting systems (evaporative cooling) to keep temperatures within the optimal 20°C to 28°C range for leafy greens.
3. Monitoring the System by us
You cannot manage what you do not measure. A robust monitoring setup uses three main components:
Digital Thermometer/Hygrometer
Used for air temperature and humidity. Look for a model that records Min/Max levels so you can see if the temperature spiked or dropped while you were asleep.
Waterproof Probe (NTC Thermistor)
Standard digital thermometers won't work underwater. You need a dedicated pH/EC/Temp combo meter with a waterproof probe that stays submerged in the reservoir.
IoT & Automation (Smart Monitoring)
Modern setups use IoT Sensors (like those used by UrbanKisaan) to send data to your phone.
Smart Plugs: You can set a "Trigger" where if the temp sensor hits 26°C, the smart plug automatically turns on the exhaust fan.
VPD Monitoring: Advanced monitors calculate Vapor Pressure Deficit, which tells you if the temperature and humidity are in the "sweet spot" for plant growth.
Optimal Temperature Cheat Sheet.
Maintaining the Nutrient Solution (The Reservoir)
The "Root Zone" is the most critical area. If the water gets too warm (above 23°C/73°F), it loses its ability to hold dissolved oxygen, leading to root rot (Pythium).
Cooling Techniques
Water Chillers: The gold standard. A chiller sits outside the reservoir and pumps the water through cooling coils.
Insulation: Use silver Mylar or bubble-foil insulation around the reservoir to reflect heat and keep the cold in.
Air Stones: While primarily for oxygen, high-volume air pumps can provide a slight evaporative cooling effect.
Submersible Coils: Some growers run cold water through a stainless steel coil inside the reservoir (heat exchanger) without mixing the fluids.
Heating Techniques
Aquarium Heaters: If your grow space is in a cold basement, a titanium or glass aquarium heater with a built-in thermostat is the simplest solution.
