The CO₂ Gro DIY Generation System (with Solenoid) is an easy-to-install CO₂ enrichment solution designed to boost plant growth, increase yields and improve overall plant health. This system provides a steady, controlled release of CO₂ — essential for maximising photosynthesis in indoor grow rooms and tents.

The included solenoid valve allows precise timing and regulation, ensuring CO₂ is delivered only when required, improving efficiency and reducing waste. Simple, effective and perfect for growers who want the benefits of CO₂ without expensive tanks or regulators.

The CO₂GRO system has been extensively trialled across a variety of popular grow tent sizes and lighting setups. Real growers have reported noticeably increased biomass, faster veg times, and denser flowers when maintaining CO₂ levels between 1,000–1,200 ppm.

From the provided results chart:

These real-world tests demonstrate that the CO₂GRO system provides consistent, repeatable CO₂ delivery, even in larger environments.

🧪 How the CO₂GRO System Works

The CO₂GRO generator uses a two-part reactive formula (Material A + Material B, sold separately) that produces a clean, high-purity stream of CO₂ when mixed. This eliminates the need for:

✅ Heavy CO₂ cylinders
✅ Expensive regulators
✅ Dangerous heating elements
✅ Complicated pressurised systems

The unit operates using simple, controllable chemical generation, paired with a precision solenoid bubble counter for predictable output.

⚙️ Included Solenoid = Full Automation

The integrated solenoid valve allows you to use:

✅ Any standard CO₂ controller
✅ Cycle & timing controllers
✅ Digital grow room climate systems

This means you can automate CO₂ delivery exactly during your lights-on period — making it efficient and cost-effective.

🌱 Why Growers Choose CO₂GRO

• Safe, controlled generation

• No risk of burning or overheating

• Lightweight & compact

• Reliable CO₂ production for up to 2–6 weeks per charge depending on tent size

• Compatible with all LED grow lighting environments

• No open flame, no heat output

🌡️ Environmental Requirements for Best Results

CO₂ enrichment only works when the environment supports high metabolic rates. Follow these guidelines:

✅ Temperature:

Maintain 28–32°C under LED lighting to ensure leaf-surface temperatures remain above 24°C.

✅ Airflow:

Use oscillating fans to ensure CO₂ reaches all canopy surfaces.

✅ Nutrient Strength:

Plants grown under CO₂ will require higher EC levels due to increased photosynthesis and nutrient demand.

✅ Lighting:

CO₂ is most effective under high-intensity LED lighting (600w+), where plants can make full use of the additional carbon.

🔬 Why CO₂ Improves Growth (Plant Science Made Simple)

• CO₂ is the carbon source used to build new plant cells.

• Higher CO₂ = faster photosynthesis = faster growth.

• Increased CO₂ lets plants use more light—meaning your LEDs become more effective.

• Plants develop thicker stems, larger leaves, and increased flower density.

• CO₂-enriched crops commonly show:
  ✅ 20–40% yield increases
  ✅ Faster veg times
  ✅ More vigorous growth
  ✅ Higher-quality flower production

✅ Safety & Best Practices

• Always run CO₂ only during lights-on

• Avoid exceeding 1,500 ppm

• Use a CO₂ monitor for accuracy

• Ensure adequate airflow & extraction

• Keep the generator upright and in a stable position

• Store reactants safely, away from children & pets
