VIVOSUN GrowHub Controller E42A for Grow Tent

The GrowHub E42A unifies equipment management for a streamlined climate strategy. It includes a built-in temperature and humidity gauge with a single probe to monitor internal and external conditions. The platform allows viewing data and programming via an app, enabling fully automated control over lighting, spectrum, on/off cycles, fan speed, and airflow. This makes it practical for growers seeking remote adjustments while maintaining precise environmental targets. The device supports per-device or unified control across smart garden components.

Key capabilities include: real-time environmental monitoring, multi-device automation, and remote scheduling. With E42A, you can tailor growth stages by adjusting light intensity and spectrum, programming ventilation cycles, and optimizing airflow to maintain stable VPD. The system is suited for growers who want a single platform to coordinate lights, fans, and sensors without juggling multiple apps or controllers.

VIVOSUN GrowHub Outlet Controller A22

The A22 is a smart environmental WiFi controller with a temperature and humidity sensor, designed to work with Vivosun’s GrowHub ecosystem. It unifies equipment by allowing individual device control or integration with the GrowHub A22 for centralized management. The outlet supports app-based automation that operates locally even if the internet is unavailable, ensuring uninterrupted growth cycles. Real-time alerts help you respond quickly when conditions cross the desired thresholds, enhancing safety and reliability in restricted spaces.

Highlights include its offline operation capability, precise environmental triggering, and ETL-certified safety features. This outlet is ideal for growers who want scalable control—starting with basic devices and expanding to more complex setups while preserving a stable environment through automation and push notifications.

VIVOSUN GIY Smart Grow Tent System 2.7×2.7

This all-in-one grow tent kit combines a 32x32x63 inch tent, a 150W full-spectrum LED light with an integrated circulatory fan, and the GrowHub E42A Controller to centralize management. The inclusion of an air circulation system helps deliver even canopy coverage, while the PWM-controlled, energy-efficient fan minimizes noise. The kit’s full-spectrum LED is designed to pair with a circulatory fan to maintain air movement and temperature consistency across the canopy, contributing to healthier plant development and uniform yields.

Consider the complete setup if you want a turnkey solution with built-in scheduling, climate monitoring, and centralized control. The system emphasizes energy efficiency, quiet operation, and a streamlined workflow for hobbyists and small-scale growers seeking a compact, all-in-one solution with room to grow.

VIVOSUN GrowHub Outlet Controller A10

The A10 outlet controller focuses on seamless automation and simplified management. It supports app-based scheduling to automate device control while maintaining a stable environment. The device functions locally, reducing the impact of internet outages on ongoing growth cycles. It’s designed for growers who want reliable, plug-and-play control over individual devices with the flexibility to expand within the GrowHub ecosystem.

Notable features include the ability to unify devices under a single platform, enforce consistent environmental parameters, and receive alerts if temperature or humidity drift beyond setpoints. The A10 is well-suited for growers starting with essential automation and gradually adding more devices to extend control as needs evolve.

AC Infinity Controller 69 PRO+ 8-Port

The AC Infinity Controller 69 PRO+ offers eight independent ports for devices like fans, lights, heaters, and humidifiers. It enables advanced automation through temperature, humidity, and VPD-based rules, with programmable cycles and schedules. The Bluetooth plus WiFi capability allows remote management, while independent channel programming supports dynamic environmental control. This makes it a strong choice for growers who need robust, scalable control across multiple devices and zones within a grow tent or larger grow room.

Pro users will appreciate the ability to tailor each device’s speed or brightness in response to sensory data. The 69 PRO+ is designed for more complex environments where precise, multi-device coordination is essential to sustain ideal growth conditions across several stages of plant development.

Buying Guide: Key Purchase Considerations

1. System scope: Decide whether you need a single-controller solution or a multi-port system to manage many devices. Single-channel controllers work well for small setups, while multi-port units support larger, more complex environments.
2. Sensor quality: Look for units with reliable temperature and humidity sensors, ideally with a dedicated probe and local display. Accurate sensing directly affects the ability to maintain target VPD and plant health.
3. Automation depth: Consider whether you want basic on/off scheduling, or advanced control like VPD-based regulation, ramping light intensity, and PWM-driven fan speeds. Deeper automation reduces manual adjustments over time.
4. Connectivity and remote access: WiFi and app control enable remote monitoring and tweaking. Ensure offline operation is available so ongoing cycles aren’t disrupted by connectivity issues.
5. Safety and certifications: ETL or equivalent safety certifications for outlets reduce risk of overheating and electrical faults in humid environments common to grow tents.
6. Expandability: If you plan to grow, upgrading to more ports or adding sensors later should be possible without replacing the entire system.
7. Noise and energy efficiency: For stealth and comfort, choose devices with low-noise fans and PWM control to minimize power draw while keeping environments stable.
8. Integration with existing gear: Ensure compatibility with your current lights, fans, filters, and other accessories to avoid mismatches or limited functionality.

Choosing the right grow tent controller depends on your space, plant variety, and desired level of automation. A unified platform simplifies management and can improve environmental stability, while modular outlets offer flexible expansion without heavy up-front investment. Evaluate how each system handles data logging, alerting, and ease of use to ensure it fits your daily routine and long-term cultivation goals.
