AeroZesh Inline Fan with E42A Controller by VIVOSUN - smart grow tent exhaust fan

The problem this solves

Plants consume CO₂ during photosynthesis, and inside a sealed grow tent that CO₂ is quickly depleted.

Without constant air exchange, plants run out of CO₂, growth slows, and heat and humidity quickly build up.

The VIVOSUN AeroZesh Inline Fan with E42A Controller replaces stale air with fresh CO₂ while automatically controlling temperature and humidity, keeping your grow environment stable and productive.

🔥 Why growers rate it

• CO₂ air exchange → constantly replaces stale air so plants have the CO₂ needed for photosynthesis
• Smart climate automation → fan speed adjusts based on temperature and humidity conditions
• Integrated GrowHub controller → monitor environmental data in real time
• PWM EC motor design → energy-efficient airflow with strong ventilation power
• Mixed-flow fan technology → moves air efficiently through carbon filters and ducting
• WiFi app control → manage airflow and environment remotely
• Automated grow stage programming → ventilation responds to environmental changes automatically

🌱 Grow Guys tip

Fresh air equals faster growth.

Your plants need a constant supply of CO₂ to photosynthesise. Proper ventilation pulls stale air out of the tent and replaces it with fresh air, while the smart controller keeps temperature and humidity from drifting outside ideal ranges.

🛠️ How to dial it in properly

Install near the tent ceiling

Warm air rises, so positioning the fan at the top of the grow tent removes heat and humidity efficiently.

Maintain fresh CO₂ supply

Running ventilation regularly replaces depleted CO₂ inside the tent, which is essential for healthy plant growth.

Connect to the GrowHub controller

Attach the fan to the E42A controller so airflow automatically responds to temperature and humidity levels.

Program environmental triggers

Set temperature and humidity thresholds so the fan increases speed when the grow environment starts to drift.

Balance intake and exhaust

Pair the exhaust fan with passive intake vents or intake fans so fresh air and CO₂ can enter the grow space.

🧩 What it pairs with

The VIVOSUN AeroZesh inline fan is the central airflow component in an indoor grow system.

Growers typically pair it with carbon filters, ducting, and circulation fans to control odor while maintaining strong air movement inside the canopy.

Ventilation also works alongside LED grow lighting and environmental controllers to stabilise temperature, humidity, and CO₂ exchange inside grow tents.

When integrated into the GrowHub smart ecosystem, airflow, lighting, and environmental monitoring can work together automatically to maintain consistent grow conditions.

❓ Frequently asked questions

What does the VIVOSUN AeroZesh fan with E42A controller do?

The VIVOSUN AeroZesh inline fan ventilates grow tents while the E42A controller monitors temperature and humidity.

Together they automate airflow to maintain stable environmental conditions.

Why is ventilation important for plant growth?

Plants require CO₂ for photosynthesis, and enclosed grow tents quickly run out of fresh air.

Ventilation replaces stale air with fresh CO₂ while controlling temperature and humidity.

Can the fan be controlled remotely?

Yes. The GrowHub E42A controller connects to the VIVOSUN app, allowing growers to monitor and adjust ventilation remotely.

Is the AeroZesh fan energy efficient?

Yes. The fan uses a PWM EC motor, delivering strong airflow while consuming less electricity than traditional inline fans.

🚀 Upgrade your grow tent airflow and climate control

Healthy plants rely on fresh air, stable temperatures, and balanced humidity.

The VIVOSUN AeroZesh Inline Fan with E42A Controller automates ventilation and environmental monitoring so growers can maintain a stable, CO₂-rich grow environment.
