Carbon tracking
Great tool for measuring CO2 in your grow. The light sensor will work accurately with an AC Infinity light. I have a Spider-Farmer light and it shows 100% while it's really running 50%.

Awesome product
So far it’s been flawless, pretty red. I’ve used it now for about four months straight and I’ve had no issues.

High quality soil probe
After integrating nearly the entire line of AC Infinity smart equipment—from the tent to the sensors—I can confidently state that this ecosystem is a game-changer for the modern grower. The level of precise automation and environmental stability achieved is simply beyond what any human could manage manually. While there was a significant hiccup, the system’s ability to recover proved its worth instantly. The Foundation: CLOUDLAB 844 & Smart Pots The CLOUDLAB 844 Advance Grow Tent is an exceptional foundation. It is incredibly durable, having stood up to multiple grows and required scrub-downs. The attention to detail is evident, with zero light leakage and smart features like internal and external closures on vent holes. It also provides the perfect built-in spot for the Controller AI+ and clean wire routing. The Heavy Duty Fabric Pots and Self-Watering Pot Bases are excellent for stability and drainage, and cleanup is easy. The Soil Sensor Probe provides accurate moisture readings, though it is crucial to note: for automatic watering integration with the AI+, you must also connect a water pump. Without the pump, the probe is for monitoring only. I. Climate Control & The AI Brain The Controller AI+ is the centerpiece, and its "AI Mode" is revolutionary. It took me just one night to achieve a stable climate score of 99, a process that used to take a week of manual tuning. CLOUDFORGE T5 Humidifier: This unit is amazing—almost like a high-powered fog machine. It can maintain a humidity difference of at least 40% (inside vs. outside the tent). The AI is expert at making the micro-adjustments needed to maintain a precise VPD target. It's barely audible, though in dry periods, expect to refill the tank up to twice a day. THERMOFORGE T3 Heater: The heater raises the temperature quickly and precisely. Crucially, its heat distribution is excellent; using a thermal camera, I didn't notice any hot spots. While I'll truly test its limits this winter, its immediate responsiveness is a major confidence booster. II. Ventilation and Airflow Synergy The true power of this system is how the components work in concert. CLOUDLINE PRO S6 Exhaust Fan: I must be transparent: my new PRO S6 fan recently failed, and I am currently dealing with support. However, this failure highlighted the value of the ecosystem. The Controller AI+ was able to compensate for the failing exhaust by adjusting the other components, saving my plants from severe stress. When working, the S6 is incredibly quiet, running at lower speeds for shorter durations because the AI is so efficient. CLOUDRAY S6 Fans (Circulation): These fans are unbelievable in quality and mounting couldn't be easier (direct to the tent poles). The AI controls them perfectly to prevent dead spots and, critically, serves as a crucial backup component if the main exhaust malfunctions. Noise & Odor: The Air Carbon Filter performs brilliantly on odor control and includes two pre-filters, which is fantastic for managing sticky residue during the flowering stage. The Noise Reduction Clamp/Duct Coupler contributes significantly to making the whole system run discreetly. The Ecosystem Verdict: Unmatched Stability The Ecosystem Synergy is the single most compelling result. My plants are responding with faster, healthier growth, and my personal stress level at the start of a new grow is dramatically reduced. Being able to look at the controller and see not only the current conditions but also the data logging of how things have been regulated over the past 24 hours (light on and off) provides a level of peace of mind I never had before. This system takes the guesswork out of climate stability. Biggest Pro: The AI’s ability to compensate for equipment failure (like the exhaust fan) and maintain a stable climate. It’s an insurance policy. Biggest Con: The fan failure issue with a new unit is a definite quality control concern. Furthermore, the Soil Sensor Probe requires a separate water pump for true auto-watering integration, increasing the overall cost for full automation. Despite the temporary fan issue, the overall functionality, precision, and risk mitigation offered by the AC Infinity ecosystem makes it an outstanding investment and a solid 5-star experience.

Valuable Sensor
Sensor works great but won't be included in the AI control segment of your controller until you have a pump connected to the system.

Help your mush with this!!
So far after a few weeks testing this sensor in my mushroom grow. I can say its made my experience so much more streamlined and automated. After calibrating it outside, which is typically 300-400ppm. I set it at 450ppm to be safe, its kept my blue oysters from aborting or "blotch". And also rhe biggest thing is it has saved me power by only allowing the fan on when its at the high c02 set (750ppm) and adjusting frequency as fruiting happens. Just set the vent fan to c02 fan in the app. Goodluck!!! Mush love!!

Very helpful
Works as it says. Great product.

Useless for me.
I’m wish I got to use this, but my AC INFINITY Ai controller only has two ports to use for sensor readings. The AC INFINITY rep confirmed it. Sad they only started out with 2 sensor ports. But 8 device control ports? Made a sensor splitter please! Returned immediately!

To many limits
Not real sure of the purpose of this. It looks like a level sensor since you can submerse it but I don’t see a way to make it change from “if dry turn water pump on” when I really want it to be if dry do not turn pump on. But there is also the limitations of only 2 sensor ports. To use this one I need to remove the CO2/light sensor. This system could be so much more with all the devices and sensors but being limited to 2 sensors sucks

Funciona correctamente como todo lo que hace ac infinity

Finger weg. China Schrott. Und lässt sich sowieso nicht im AI-Mode vom Controller nutzen. SCAM !!!

Naja. Co2 misst er ja. Aber Licht in Prozent? Wie amateuhaft. Da gibt es bessere Made in Germany. Einfach mal googeln
