Pro-Leaf CO2 Generator Kit 4 Burners + PPM-B1 Controller

You have the best lights, premium nutrients, and high-end genetics, but are you still hitting a "yield ceiling"? The Pro-Leaf CO2 Generator Kit with 4 Burners and PPM-B1 Controller is the professional tool that unlocks the true biological potential of your indoor crop, transforming light into biomass like never before.

Why your plants need this CO2 system

Problem: In a sealed grow room, vigorous plants devour the available CO2 in minutes. Once levels drop below 300 ppm, photosynthesis stalls completely. Your expensive LED or HPS lights keep running, but the plants simply cannot "eat" the light energy without carbon dioxide, creating a hidden bottleneck in your cultivation.

Agitation: It is incredibly frustrating to invest time and money into electricity and fertilizers only to get fluffy buds or average harvests. This invisible deficiency is the main reason why many advanced growers fail to reach that coveted "gram per watt" goal. You are essentially starving your plants of their primary food source while blasting them with light.

Solution: The Pro-Leaf Kit solves this equation instantly. By combining a powerful 4-burner generator with the brain of the PPM-B1 controller, you ensure your plants always bathe in the optimal 1200–1500 ppm range. This turns your grow room into a high-performance engine, fueling explosive growth and significantly denser flowers.

How the Pro-Leaf Kit transforms your cultivation

Adding this system is not just an upgrade; it is a change of category. By maintaining stable high levels of CO2, your plants become more resistant to heat (allowing you to run temperatures up to 30°C) and metabolize nutrients much faster. The included PPM-B1 Controller acts as the brain of the operation, constantly sniffing the air and firing the burners only when needed, ensuring precision without waste.

This kit is essential for those using high-intensity lighting. If you are pushing high PPFD levels, this climate control solution is the missing link to convert that light intensity into actual physical weight.

Key features and benefits (FAB)

• 4-Burner Brass System: The four burners provide a rapid output of CO2, capable of saturating medium to large grow rooms quickly. Advantage: Reduces the "on" time required to reach target levels. Benefit: More stable environment and efficient gas usage.
• Intelligent PPM-B1 Controller: A digital sensor that monitors CO2 levels in real-time. Advantage: Fully automated "set-and-forget" operation. Benefit: Total peace of mind knowing your levels are perfect without you having to be there.
• Electronic Ignition & Safety Valve: Features a solenoid valve and tilt switch. Advantage: The system shuts off immediately if the unit falls or the flame goes out. Benefit: Guarantees the safety of your home and grow space.
• Liquid Propane (LP) Combustion: Burns clean and produces water vapor and CO2. Advantage: Adds slight humidity which is often needed under hot HID lights. Benefit: Creates a lush, tropical environment that plants love.

Steps to set up your CO2 enrichment system

1. Positioning: Hang the generator at least 50cm below the ceiling and away from flammable materials. CO2 is heavier than air, but the heat will make it rise initially before falling over your canopy.
2. Sensor Placement: Place the PPM-B1 sensor at plant canopy height. This ensures the controller reads exactly what your plants are breathing.
3. Connections: Connect the gas regulator to your propane tank and the controller to the generator. Ensure your Air Extraction System is timed correctly (you don't want to extract while enriching).
4. Set the Target: Dial in your desired PPM (usually 1200-1500 PPM for flowering) on the controller.
5. Monitor: Check the digital display daily to ensure levels are maintained and the tank has gas.

Frequently Asked Questions

Is this kit safe to use in a home grow?

Yes, it is designed with multiple safety features, including electronic ignition and a tip-over switch that cuts the gas if the unit falls. However, proper installation and checking for leaks with soapy water is mandatory. Always ensure you have a carbon monoxide detector in the room as a precaution.

How much heat does it produce?

Since it uses combustion, it does generate heat. This is actually a benefit in winter or with LED setups that run cool. However, in summer, you must ensure your cooling or ventilation system can handle the extra BTUs.

What size room is this suitable for?

The 4-burner model is powerful. It is ideal for spaces ranging from 3x3 meters up to 6x6 meters. For smaller tents, a 2-burner model or bottled CO2 for plants might be more appropriate to avoid overheating.

Personal Experience of Pevgrow’s CEO (Alan)

I remember the first time I switched from passive CO2 bags to a proper burner system like the Pro-Leaf. The difference wasn't subtle—it was shocking. By the third week of flowering, the buds were noticeably harder and the plants seemed to be on steroids, drinking more water and asking for more food than ever before.

One trick I learned with this specific kit: set the PPM-B1 controller to stop dosing about an hour before the lights go out. Plants don't use CO2 in the dark, so you save gas, and the residual levels are enough to finish the day. It’s a small efficiency tweak that saves you a tank refill over the course of a cycle.
