Smart Ventilation for Indoor Growing
Indoor growing environments constantly change.
Grow lights generate heat, plants release moisture through transpiration and irrigation can cause temporary humidity increases. As plants become larger, their ventilation requirements can also increase significantly.
The AC Infinity CLOUDLINE T Series allows growers to automate much of this process.
Instead of operating continuously at one fixed speed, the fan can respond dynamically according to:
Temperature + Humidity + VPD + Time
This allows the ventilation system to maintain gentle background airflow and automatically increase extraction when environmental conditions require additional ventilation.
CONTROLLER 69 PRO Smart Environmental Control
Current CLOUDLINE T Series packages feature the AC Infinity CONTROLLER 69 PRO, providing advanced environmental monitoring and automation.
The controller allows compatible equipment to respond to programmed environmental conditions rather than requiring constant manual adjustment.
Temperature Control
The CLOUDLINE T Series can automatically increase ventilation when temperatures rise beyond programmed levels.
This helps exhaust heat generated by:
- Grow lights
- Pumps
- Environmental equipment
- Electrical equipment
- Warm ambient conditions
Removing warm air and introducing replacement air can help maintain a more stable indoor growing environment.
Humidity Control
Plants continuously release moisture through transpiration.
As the canopy develops, humidity management can become increasingly important, particularly during flowering and lights-off periods.
The T Series can respond automatically to relative humidity conditions, increasing extraction when programmed thresholds are reached.
This can be particularly useful during:
- Dense vegetative growth
- Flowering
- High-transpiration periods
- Humid weather
- Lights-off periods
- High-density cultivation
VPD Control
The CONTROLLER 69 PRO also supports Vapour Pressure Deficit (VPD) monitoring and automation.
VPD considers the relationship between temperature and relative humidity, providing growers with another way to assess atmospheric conditions surrounding their plants.
VPD-based programming makes the CLOUDLINE T Series particularly useful for growers wanting more advanced environmental management than simple temperature or humidity triggers alone.
Timer, Cycle & Schedule Programming
Ventilation can also be programmed around time rather than environmental conditions alone.
Available programming options allow growers to create operating schedules, repeating cycles and minimum fan-speed settings.
This provides flexibility for different:
- Day and night periods
- Vegetative environments
- Flowering environments
- Seasonal conditions
- Ventilation strategies
Wi-Fi & Bluetooth Connectivity
The CONTROLLER 69 PRO provides Wi-Fi and Bluetooth connectivity, allowing compatible equipment to be monitored and controlled through the AC Infinity app.
Depending on system configuration, growers can access:
- Fan-speed control
- Temperature monitoring
- Relative humidity monitoring
- VPD monitoring
- Environmental automation
- Device programming
- Alerts and notifications
- Historical environmental information
- Climate trends
This allows growers to monitor environmental changes over time rather than relying solely on a single current reading.
AC Infinity UIS Integration
The CLOUDLINE T Series forms part of the wider AC Infinity UIS ecosystem.
Compatible UIS equipment can be connected through the environmental controller, allowing multiple components of the growing environment to work together.
Compatible AC Infinity Equipment
A smart growing environment can incorporate compatible:
- CLOUDLINE inline fans
- CLOUDRAY circulation fans
- IONFRAME grow lights
- CLOUDFORGE humidifiers
- UIS environmental accessories
This allows growers to create a coordinated climate-control system rather than operating each device independently.
Quiet EC Motor Technology
The CLOUDLINE T Series uses an energy-efficient EC motor with PWM digital control.
This technology provides precise speed adjustment across a broad operating range.
Benefits of EC Motor Technology
- Quiet operation
- Smooth speed adjustment
- Efficient power consumption
- Reduced motor heat
- Precise airflow management
- Excellent low-speed performance
Low-speed operation is particularly useful in indoor cultivation because maximum extraction isn't required continuously.
The fan can maintain gentle background ventilation before automatically increasing airflow as environmental conditions change.
Mixed-Flow Impeller Technology
Maximum unrestricted airflow isn't the only consideration when choosing an inline fan.
Real-world ventilation systems introduce airflow resistance through components such as:
- Carbon filters
- Flexible ducting
- Duct bends
- Silencers
- Reducers
- Exhaust outlets
- Intake restrictions
The CLOUDLINE T Series uses a mixed-flow impeller design engineered to maintain effective airflow under the resistance commonly encountered in grow-room ventilation systems.
Carbon Filter Compatibility
The CLOUDLINE T Series can be paired with an appropriately sized AC Infinity Carbon Filter to create a complete grow-room extraction system.
Typical Extraction Configuration
Carbon Filter → CLOUDLINE T Series Fan → Ducting → Exhaust
This configuration can provide:
- Air exchange
- Heat extraction
- Humidity management
- Odour filtration
- Negative-pressure management
For best performance, the duct diameter of the fan, carbon filter and ducting should be appropriately matched.
Negative Pressure
A correctly sized CLOUDLINE extraction system can help maintain negative pressure inside a grow tent.
When extraction airflow exceeds the available intake airflow, the tent walls will typically pull inward slightly.
Maintaining negative pressure helps direct exhaust air through the intended ventilation and carbon-filtration pathway rather than allowing untreated air to escape through openings in the tent.
Detachable Motor Housing
Ventilation equipment gradually accumulates dust and airborne particles.
The CLOUDLINE design allows the motor and impeller assembly to be detached from the mounting system, simplifying periodic cleaning and maintenance.
This is particularly useful when the inline fan is installed above a grow tent or permanently connected to a ducting system.

Which Series Should You Choose?
Choose the CLOUDLINE S Series when you primarily require high-quality adjustable ventilation without advanced environmental automation.
Choose the CLOUDLINE T Series when you want the extraction system to automatically respond to changing grow-room conditions.
Choosing the Correct CLOUDLINE T Series Fan
Selecting the correct inline fan involves more than matching the fan to the dimensions of the grow tent.
Factors to Consider
- Grow tent or room volume
- Required air exchange
- Grow-light heat output
- Ambient temperature
- Ambient humidity
- Carbon-filter resistance
- Duct length
- Number of duct bends
- Intake restrictions
- Silencers
- Required negative pressure
- Desired operating noise
Carbon filters, bends and long ducting runs can reduce real-world airflow.
Choosing appropriate additional capacity can allow a fan to operate at quieter lower speeds during normal conditions while retaining extra ventilation capacity for hotter or more humid periods.
