Prima Klima 125mm EC-THC Extractor Set – Automated Temp & Humidity Control · 680 m3/h

The Prima Klima 125mm EC-THC Extractor Set is a complete, professional-grade ventilation kit designed to automate your grow room's climate and eliminate odors instantly.

Are you tired of constantly checking your indoor garden to make sure your plants aren't roasting or drowning in humidity?

Fluctuating temperatures and high moisture levels are the silent killers of a great harvest. Without proper ventilation, you're risking heat stress, stunted growth, and the dreaded bud rot. Plus, dealing with loud, inefficient fans and paranoia-inducing odors leaking out of your setup is enough to ruin the chill vibe of growing. It turns what should be a relaxing hobby into a stressful chore.

Enter the Prima Klima EC-THC ventilation kit. This beast automatically adjusts its speed based on your preset temperature and humidity levels, keeping your canopy in the sweet spot 24/7. Paired with a premium K2601-flat-125 carbon filter, it guarantees a stealthy, perfectly balanced environment so you can finally relax and watch your girls thrive.

What it feels like to grow with the Prima Klima EC-THC Set

Imagine zipping up your tent and knowing everything is handled. No more waking up in the middle of the night wondering if the lights made the room too hot. The EC motor is incredibly quiet and highly efficient, meaning you won't have to deal with that annoying jet-engine hum in your house. It just hums along smoothly, ramping up only when necessary.

Emotionally, it is pure peace of mind. You get that "pro" feeling knowing your environment is dialed in automatically. And when it comes to discretion? The included carbon filter scrubs the air so thoroughly that you won't smell a thing outside the tent. It is stealthy, smart, and gives you the confidence to push your genetics to their absolute limit.

How to squeeze the experience to the max

To get the absolute best performance out of this 680 m3/h powerhouse, you need to set it up right. Here is how you can maximize its potential:

• Place the sensor at canopy level: The temperature and humidity probe should hang right where your top colas are, as this is the microclimate that matters most.
• Keep ducting straight: Use the included 3-meter 127mm ducting with as few bends as possible to maintain maximum airflow efficiency.
• Pair it with the right space: This kit is perfect for medium to large grow tents, easily handling spaces up to 1.5m x 1.5m.
• Set realistic targets: Program your max temperature around 25-27°C (77-80°F) and humidity according to your plant's current life stage (higher for veg, lower for flower).
• Check your negative pressure: Ensure your intake is slightly smaller than your exhaust to keep the tent walls sucked in, guaranteeing zero odor leaks.

How it fits with other products in your set-up

This extractor set is the beating heart of your climate control strategy. It works beautifully alongside oscillating clip fans and humidifiers. When your lights kick on and generate heat, the Prima Klima fan automatically ramps up to extract the hot air, creating a seamless synergy with your lighting rig.

If you are upgrading your entire air extraction system, this kit replaces the need for separate fan speed controllers and hygrometers. It is an all-in-one command center that simplifies your entire hardware ecosystem.

Frequently Asked Questions

Is the Prima Klima EC-THC fan loud?

Not at all! Thanks to the modern EC motor technology, it operates much quieter than traditional AC fans, especially when running at lower speeds. It only ramps up to full power when your temperature or humidity exceeds the limits you set.

How often do I need to replace the carbon filter?

Under normal continuous use, the K2601-flat-125 carbon filter will effectively scrub odors for about 12 to 18 months. We recommend changing it after every 3-4 successful harvest cycles to ensure maximum stealth.

Can I use this kit for both vegetative and flowering stages?

Absolutely. You simply adjust the target humidity dial on the fan. Set it higher during veg when plants love moisture, and dial it down during flower to keep the air dry and prevent mold.

Does the kit include everything I need to hang it?

The kit includes the fan, filter, 3 meters of ducting, a metal clamp, and a connector. You will just need some standard rope ratchets or zip ties to physically hang the unit from your tent's ceiling bars.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested countless extraction setups over the years, and the Prima Klima EC-THC is easily one of my favorites for medium-sized tents. I use it in my personal 120x120cm setup. What I notice immediately is the stability; I used to constantly tweak my manual fan speed controller every time the seasons changed or a heatwave hit. Without this automated system, I'd definitely be losing sleep over humidity spikes during late flower. The trick you only learn by trying? Don't place the sensor probe directly under an intense LED light, or it will read the radiant heat rather than the ambient air temperature, causing the fan to run harder than necessary. Tuck it just under a top leaf in the canopy for the most accurate reading. Grab yours today and take the guesswork out of your grow!
