Vivosun AeroWave E9 Grow Tent Clip-On Fan | 2 Pack

The 2-pack configuration provides comprehensive air circulation coverage throughout your entire grow space. Position one fan above the canopy for general circulation and a second at mid-canopy or lower level to ensure airflow reaches all plant zones. This dual-fan setup eliminates stagnant air pockets, prevents hot spots, strengthens stems at different heights, and creates more uniform growing conditions. It's particularly beneficial for larger tents (4x4 feet and up) or dense canopies where a single fan can't reach all areas effectively.

Yes, when connected to a VIVOSUN GrowHub E42/E42A/E25 controller, each fan can be controlled independently through the VIVOSUN app. This allows you to set different speeds for each fan—for example, running the upper fan at higher speed for general circulation while keeping the lower fan at a gentler speed for seedlings or young plants. You can also set individual timers, create custom schedules, and integrate both fans into automated grow recipes through SGS.

The AeroWave E9 2-pack is ideal for medium to large grow tents ranging from 4x4 feet up to 5x9 feet or larger. For a 4x4 tent, the dual-fan setup provides excellent coverage with one positioned high and one low. For larger tents like 5x5 or 5x9, position the fans at opposite ends or corners to create cross-circulation patterns. The powerful EC motors and 80° oscillation on each fan ensure adequate airflow even in spacious growing environments.

The most effective dual-fan setup positions one fan above the canopy angled slightly downward for general air movement, and the second fan at mid-canopy or below the canopy angled upward. This creates vertical circulation that moves air through all plant zones. Alternatively, position both fans at canopy height on opposite sides of the tent for horizontal cross-circulation. Adjust the 80° vertical angles on each fan to avoid direct constant airflow on plants while ensuring the oscillation patterns overlap for complete coverage.

No, even with both fans running, the noise level remains very reasonable. Each AeroWave E9 operates at just 36 dB(A), and running two simultaneously typically results in combined noise around 40-42 dB(A)—still quieter than normal conversation. The EC motors are specifically designed for quiet operation, making the 2-pack suitable for residential growing environments where noise control is important. You can also run the fans at lower speeds during sensitive periods for even quieter operation.

Both fans work perfectly as standalone units with manual control (5 speeds each) and automatic oscillation. However, connecting both to a GrowHub controller unlocks their full potential: 10 speeds per fan, remote WiFi control, independent timer settings, coordinated automation, and SGS integration. You can choose to connect both fans for complete smart control, or run them manually if you prefer simpler operation without app connectivity.

When both fans are set to Natural Wind Mode, they independently vary their speed and intensity to simulate natural outdoor wind patterns. This creates a more dynamic airflow environment where air movement changes constantly rather than remaining constant—just like plants experience outdoors. The dual-fan setup enhances this effect by creating varied airflow from multiple directions and heights, significantly reducing plant stress, encouraging stronger stem development, and promoting more resilient growth throughout your entire canopy.

Each fan operates independently with its own obstacle detection system. If one fan encounters an obstruction (such as a plant branch growing into its oscillation path), that specific fan will automatically retract or stop oscillating in that direction to prevent damage. The other fan continues operating normally. This independent safety feature ensures both fans can adapt to your growing canopy separately, preventing motor damage while maintaining airflow where unobstructed.

Absolutely. The AeroWave E9 fans are designed to work individually or in multiples. If you expand to a larger tent or add a second growing space, you can purchase additional AeroWave E9 fans (single or 2-pack) and integrate them into your existing VIVOSUN smart system. All AeroWave E9 fans connected to the same GrowHub controller can be managed together through the app, allowing you to scale your air circulation system as your growing operation expands.
