5. Operating Instructions
5.1. Environmental Responsive Control
The iControl automatically adjusts fans, humidifiers, and dehumidifiers to maintain target temperature, humidity, and VPD (Vapor Pressure Deficit) parameters. Set your desired environmental conditions through the controller's interface or the MARS HYDRO app.
Figure 5.1: Smart Climate, Effortless Control. This image demonstrates the iControl's ability to maintain a perfect climate by automatically adjusting fans and ventilation based on preset conditions.
5.2. Stage-Based Smart Automation
Configure customized lighting and climate strategies for different growth phases (seedling, vegetative, flowering). The system will automatically transition between stages based on your preset timelines, ensuring consistent ideal conditions.
5.3. Precision Light Control
Manage your grow lights with automated on/off cycles, dimming, and sunrise-to-sunset simulation. If equipped with an optional PPFD sensor, the system can automatically adjust light intensity to meet target PPFD values for each growth stage.
Figure 5.2: Precision Light Control, Smarter Growth. This image illustrates the iControl's features for managing grow lights, including timers, scene settings, dimming, and PPFD adjustments for different plant growth phases.
5.4. Smart Soil Sensor (Optional)
With an optional soil sensor, monitor root-zone temperature, humidity, and EC (Electrical Conductivity) with precision. This data allows for informed adjustments to water and nutrient delivery, promoting healthier root development.
5.5. Smart CO2 Balance (Optional)
Integrate an optional CO2 sensor to accurately monitor CO2 levels. The iControl can connect with an iHub (sold separately) to automate your CO2 generator, maintaining optimal CO2 concentrations for faster, healthier plant growth.
5.6. Remote App Control & Data Logging
The MARS HYDRO app provides real-time monitoring of all environmental parameters and connected devices. Access detailed data logs to track historical conditions and optimize your grow strategy. Manage devices, adjust settings, and receive alerts from anywhere.
