125mm TT Extraction Kit – Complete Air & Odor Control System

The 125mm TT Extraction Kit is the definitive all-in-one solution designed to take the headache out of managing your indoor crop's climate, providing you with the necessary tools to evacuate heat and scrub the air of strong cannabis aromas before they leave your tent. If you are looking for a system that balances power, silence, and total discretion, this combo is the backbone your setup needs.

Is your grow room environment out of control?

Without a proper extraction system, an indoor grow quickly descends into environmental chaos. Heat pockets form around your lights, burning the tips of your plants, while humidity spikes create the perfect breeding ground for mold. Worst of all, the intense aroma of flowering buds permeates every corner of your house, turning what should be a private hobby into a source of paranoia and risk.

This disorder doesn't just stress you out; it ruins your harvest. Stagnant air slows down photosynthesis, and high temperatures produce airy, loose buds. Trying to manage this by just opening a window or using small clip fans is a waste of time and compromises the security of your operation. You end up constantly checking the thermometer and worrying about the neighbors instead of enjoying the process.

The 125mm TT Extraction Kit brings order to this atmospheric mess. By creating a constant negative pressure, it forces fresh air in and pushes hot, scrubbed air out. It simplifies your setup by giving you exactly what you need—fan, filter, and ducting—matched perfectly to work together, putting you back in control of the environment.

How your space changes once you add it

The difference between a stagnant tent and one with this kit is night and day. Visually, your setup looks professional; the flexible ducting creates a clear path for airflow, removing the clutter of makeshift fans. But the real change is in the "invisible" order: the temperature stabilizes, and the heavy, humid air is constantly replaced.

Practically, this means you can close the zippers of your Grow tents and walk away with peace of mind. No more rushing home to check if the lights are cooking your plants. The air flow becomes consistent, and the smell is neutralized at the source, allowing you to breathe easy in your own home.

What you can control with this product

This kit isn't just about moving air; it's about organizing the vital parameters of your grow. Here is what you bring under control:

• Temperature: Evacuates the heat generated by HPS or LED lights directly.
• Humidity (RH): Removes moisture released by plant transpiration, preventing rot.
• Odors: The Odorsok filter traps volatile terpenes, ensuring total discretion.
• CO2 Levels: Constantly replenishes CO2-depleted air with fresh air for growth.
• Air Circulation: Prevents micro-climates and strengthens plant stems.

Steps to build your organised ventilation set-up

1. Check your flow: Identify the extraction ports on the roof or upper side of your tent.
2. Prepare the filter: Place the Odorsok filter inside the tent at the highest point (heat rises).
3. Connect the ducting: Attach a piece of the flexible aluminum tube to the filter and secure it with a clamp.
4. Mount the extractor: Connect the other end of the tube to the TT extractor (ensure the arrow points OUT of the tent).
5. Route the exhaust: Run the remaining ducting from the fan output to a window or vent.
6. Seal and Test: Turn it on and check for leaks with your hand; negative pressure should suck the tent walls in slightly.

Advantages and benefits of having everything in its place

Installing this Air Extraction System translates technical features into real improvements for your life as a grower:

• Peace of mind: The Odor eliminator for weed capability means no smells greeting guests at the door.
• Bigger Yields: Plants in a stable climate grow faster and produce denser flowers.
• Less Maintenance: Automated climate control means less time tweaking manual fans.
• Stealth: The TT motor is designed to be quieter than standard inline fans, keeping your hobby secret.
• Versatility: The 2-speed switch lets you lower power during the seedling stage and blast it during flowering.

Frequently Asked Questions

How much space does this kit cover?

The 125mm TT kit is optimized for spaces ranging from 0.80m² up to 1.20m² (approx. 120x120x200cm tents). For larger rooms, you might need the 150mm version.

Where should I place the extractor?

Ideally, the filter goes inside the tent at the top. The extractor can be placed inside or outside the tent, but placing it outside saves vertical space for your plants.

How do I clean the Odorsok filter?

One of the great advantages of the Odorsok filter included is that it is machine washable. You can wash it after a cycle to recover efficiency, though for maximum odor control, we recommend replacing it every 2-3 crops.

Is the fan loud?

The TT 125 produces between 28 and 36 dB, which is roughly the sound of a whisper or a quiet library. It is much quieter than cheap axial fans.

Personal Experience of Pevgrow’s CEO (Alan)

I've set up dozens of tents over the years, and the 125mm TT Kit is usually my go-to recommendation for anyone starting with a standard 1.2-meter tent. What I really appreciate about this specific kit is the inclusion of the Odorsok filter. Unlike the heavy steel carbon filters that are a nightmare to hang alone without dropping them on your plants, the Odorsok is incredibly lightweight.

My personal trick? I always run the fan on speed 1 during the vegetative stage to maintain humidity, and switch to speed 2 the moment I flip to 12/12 flowering. This keeps the noise down when the plants are small and ensures maximum odor scrubbing when the terpenes really start to kick in. It’s a simple "set and forget" system that just works.
