Lucius CO2 Sensor (0-3000 ppm) - Plug-In Grow Room CO2 Monitor for the 720W Triple Black LED

Stop Guessing Your CO2. See the Exact PPM on Your Light.

You are running a 720W Triple Black at serious intensity. At that light level, CO2 is usually the thing holding your plants back. Too little and you are wasting the light you paid for. Too much and you are wasting gas and money. The Lucius CO2 Sensor plugs straight into your light's built-in touchscreen controller and shows you the live PPM in your grow room, so you know instead of guess.

Built for One Light. Plugs Straight In.

This sensor connects directly to the 720W Samsung LM281B LED Grow Light with Integrated Touchscreen Master Controller | Lucius Triple Black Label. No separate controller to buy. No hub. No app subscription. Plug it in and your CO2 reading appears on the screen you already own, as part of the light's smart environmental control system.

Why Your CO2 Number Matters

• High light needs more CO2. Outdoor air sits at roughly 420 ppm. A tent or room full of healthy plants under a 720W LED can pull that down during lights on, and growth slows with no visible warning.
• Enrichment only pays if you can measure it. Growers who supplement typically aim for around 1 000 to 1 500 ppm under high intensity LED. Without a sensor you are releasing gas blind.
• It tells you if your ventilation is doing its job. If your PPM drops hard during lights on, your fresh air exchange is not keeping up. That is a cheap fix once you can see it.

What You Get

• Real time CO2 monitoring inside your controlled grow environment.
• Wide 0 to 3 000 ppm range that covers everything from a depleted tent to a fully enriched sealed room.
• Direct integration with the Triple Black touchscreen master controller. One screen for light, schedule and environment.
• Better decisions around CO2 supplementation. Dial in your release, stop overdosing, stop underdosing.
• Genuine Lucius hardware from South Africa's Lucius Lighting specialists, with local support.

Setup in Three Steps

1. Mount the sensor at canopy height, away from the direct stream of your CO2 outlet or intake fan.
2. Plug it into the sensor port on your 720W Triple Black.
3. Read your live PPM on the light's touchscreen.

Who This Is For

• Growers already running CO2 from a cylinder, generator or bags who want to see what they are actually achieving.
• Sealed room and high intensity growers chasing maximum yield per watt.
• Tent growers who want proof that their extraction and fresh air are keeping up.

Frequently Asked Questions

Will it work with other lights or controllers?
It is designed for the touchscreen controller on the 720W Lucius Triple Black. If you run a different Lucius model, message us before ordering and we will confirm compatibility for you.

Does it switch my CO2 regulator on and off?
It is a monitoring sensor. It gives you the live number so you can set your release correctly. Dosing equipment is separate.

I do not add CO2. Is it still worth it?
Yes. It shows whether your plants are running short of CO2 during lights on, which is one of the most common hidden causes of slow growth in tents.
