Smart Control through the Spider Farmer App
Start Time / End Time: Set when the fan should turn on and off automatically.
Operation Speed: Fan speed during active time.
Standby Speed: Fan speed during off-time. It must be lower than the operation speed. If not set, the fan stays off during standby.
Start Time: When the fan starts its first cycle.
Run Time: Duration the fan stays ON in each cycle.
Closing Time:Duration the fan stays OFF in each cycle.
Execution Times: Number of ON/OFF cycles to repeat.
e.g. Start at 12:00-Run 1h-Off 1h-Repeat 2 times
12:00-13:00 ON, 13:00-14:00 OFF, 14:00-15:00 ON, 15:00-16:00 OFF.
Temperature Priority Mode
For high-heat lamps or hot, dry climates.
Protects plants from heat stress and leaf burn — temperature control comes first.
Humidity Priority Mode
Best for flowering or fruiting stages.
Prevents mold and mildew when humidity exceeds 60%.
Temperature-Only Mode
Ideal for dry regions or rooms with dehumidifiers.
Fast response to heat without humidity interference.
Humidity-Only Mode
Use when temperature is stable or air-conditioned.
Focuses on moisture control, avoiding overactivation.
Temp & Humidity Combined Mode
Designed to balance temperature and humidity together.
If either parameter moves out of the optimal range, the system will trigger automatic fan adjustments to stabilize the environment.
【Quiet & Powerful】Mixed flow design combined with an EC motor that powers high-quality impellers makes this fan truly energy efficient. With only 62 watts of power but a strong airflow of up to 402 CFM, a very low noise level, and only production 32DB, this 6-inch exhaust fan is silent. Lightweight ABS blades reduce the airflow resistance and add airflow by 40%.
【Intelligent Controller】The smart controller has multiple modes for operation, 10 fan speeds, is easy to program, and controls the humidity and temperature automatically. Easy to control over the fan speed, airflow, and many other elements, stabilizing and optimizing your growth environment.
【Temperature Regulation】 Inline fans help maintain optimal temperature levels by removing hot air and exchanging it with cooler air from the outside. This prevents overheating, which can damage plants and impede growth.
【Humidity Control】 Proper humidity levels are essential for plant growth. Inline fans assist in regulating humidity by exhausting stale air containing excess moisture and bringing in fresh, drier air. This prevents the development of mold and mildew, which thrive in humid conditions.
【Air Circulation】 Good air circulation is vital for plants to receive an adequate supply of carbon dioxide (CO2) and to facilitate the process of transpiration, where plants release water vapor through their leaves. Inline fans ensure that CO2 is evenly distributed throughout the grow space and that plants receive sufficient airflow to support their growth and development.
【Pest Prevention】 Proper air circulation can deter pests by creating an environment that is less conducive to their proliferation. Additionally, inline fans can help to remove airborne pests that may otherwise settle on plants and cause damage.

Hello
I love my 6 inch exhaust fan. It works perfect for my room with two sf4000’s inside. I will be getting another one to be controlled by this digital controller for intake air. I love that it will control two fans off the one single digital controller. Thank you for your great products.
This fan and monitor are amazing! With the auto feature I don’t have to check my tent as often making growing fun again! Thanks spider farmer glad I got this before they sold out.
