Eliminate Odours.

Let’s be honest: grow tents get hot, humid, and - depending on what you’re cultivating - a bit antisocial. Left unchecked, stale air turns your lush indoor paradise into a fungal pressure cooker. That’s where the Spider Farmer 4" Inline Fan with Speed Controller storms in, all precision blades and silent efficiency, like a ninja of air movement.

This is not your average rattling desk fan with dreams of greatness. This is a high-efficiency EC inline fan, engineered by the seasoned green thumbs at Spider Farmer is built for success. Keep plants lush & healthy, eliminate odours and protect your privacy with this astonishing value EC fan. 

Full EC Control.

Before we get to the specs, let’s talk about EC motors - because this is where things get serious.

Unlike outdated AC motors, EC (electronically commutated) motors are digitally controlled, energy-efficient, and practically whisper-quiet. They run cooler, last longer, and cost mere pennies a day to operate. With precise speed control, they let you fine-tune your environment for every growth stage - veg, bloom, or "oh god, why is it 90°F in here?"

The Spider Farmer 4" Inline Fan with Speed Controller makes full use of EC tech, combining energy efficiency with brute airflow. At just 27 watts, it still churns out 205 CFM - enough to cycle the air in most grow tents multiple times per hour. And it does all that at just 26.8 decibels, which is just below the volume of your average female converstaion.

Grow Like A Genius. 

The new 2025 Spider Farmer 4" Inline Fan with Speed Controller isn’t just powerful - it’s now part of the Genius Grow System. With the addition of an RJ12 port, it connects directly to Spider Farmer’s GGS Controllers and power strip kits (sold separately). Once cabled in with the RJ12,

• You can control it via the Spider Farmer app.

• You can automate fan speeds based on temperature and humidity.

• You can stop fiddling with dials and start managing your grow like a pro.

Quiet. Cool. Discreet.

Pair this fan with a carbon filter, and suddenly, that suspicious smell leaking into your hallway disappears. The Spider Farmer 4" Inline Fan with Speed Controller excels at odour control when paired with a proper filter setup. Whether you’re growing herbs, tomatoes, or the sort of crops that raise eyebrows, this fan will keep your operation quiet, cool and discreet.

Fingertip Dimmer or App Control.

The included manual speed controller lets you dial things in just right - ideal for those who prefer hands-on control without needing the app. Crank it down during cool nights, or ramp it up on those sweltering summer days. Either way, your plants are breathing easy, and so are you.
