Description

Smart Control through the Spider Farmer App

Manual Mode

The inline fan speed can be set between 25% and 100%.
To turn off the fan, tap the toggle switch below the speed ring. 
Close CO2 Device: A GGS power strip is required.
Assign an outlet as a CO₂ device (intake or exhaust). If it’s an intake device, it will automatically turn off when the fan is running.

Time Slot Mode

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.

Cycle Mode

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.

Environment Mode

Two modes available: temperature-priority and humidity-priority. When both temperature and humidity are out of target range, temperature takes precedence.

【Quiet & Powerful】 Mixed flow design combined with an EC motor that powers high-quality impellers makes this fan truly energy efficient. With only 27 watts of power but a strong airflow of up to 205 CFM, a very low noise level, and only 26.8 DB, this 4-inch exhaust fan is silent. Lightweight ABS blades reduce the airflow resistance and add airflow by 40%.

【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.

    Love the read out and how quiet this inline is compared to others of the same size. When they say quiet they mean it, if it wasn’t for my timer I would probably forget it was on. Thanks SF!

Why Do You Need the Glow30 Side Lighting?

Most grow lights are mounted on top of grow tents, but light struggles to penetrate deep into the lower canopy. This means lower buds and branches receive less light, resulting in slower growth, smaller yields, and lower potency compared to the top. Without proper lighting,you’re not maximizing your plant’s full potential. Spider Farmer Glow30 solves this problem(Side lighting, under lighting, supplemental lighting)! It provides targeted side lighting, ensuring that lower buds receive the extra light they need to grow bigger, denser, and healthier. The flexible installation lets you mount it on grow tent sidewalls or place it anywhere for optimized light distribution. Plus, it’s super energy-efficient—just 32W! Even if you run it 4 hours per day for 21 days, your electricity cost will only be a few dollars. With better light coverage and bigger yields,Glow30 is the upgrade your grow setup needs. Length of wires at both ends of a single light bar: 70cm/25.56''
