CO2GRO Refillable CO₂ Generator Kit – Complete CO₂ Enrichment System for Indoor Grow Rooms

Increase plant growth, maximise yields and improve crop quality with the CO2GRO Refillable CO₂ Generator. Designed for indoor cultivation, this innovative CO₂ system provides an economical and reusable alternative to traditional disposable CO₂ cylinders.

Unlike heavy compressed gas bottles, the CO2GRO Generator weighs less than 7kg, measures approximately 70cm in length, and features a durable protective casing with an integrated carry handle for easy transportation and storage.

Refill packs are available separately, allowing you to continue producing high-purity CO₂ without replacing the entire unit.

Why Use CO₂ Enrichment?

Supplementing your grow room with carbon dioxide is a proven method of increasing photosynthesis, allowing plants to convert more light into energy. The result is:

• Increased plant growth
• Faster vegetative development
• Improved flowering performance
• Higher yields
• Denser, higher-quality flowers and fruit
• Enhanced overall crop performance

For best results, maintain CO₂ levels between 1,000–1,200ppm during the lighting period.

What's Included?

Every CO2GRO Generator Kit contains:

• CO2GRO Generator Bottle
• Power Adapter
• Solenoid Bubble Counter
• Filter with Dry Filter Media
• CO₂ Tubing
• Filling Funnel
• Full Instruction Manual

How It Works

The CO2GRO Generator produces high-purity carbon dioxide by combining Material A and Material B (sold separately). Once activated, the system continuously generates CO₂ for your grow room.

Simply:

1. Fill and charge the generator.
2. Adjust the integrated pressure-reducing regulator to your desired output.
3. Connect to a compatible CO₂ controller for fully automated CO₂ management.

No heavy gas cylinders. No expensive refills. Just reliable CO₂ production whenever you need it.

Filling Instructions

For optimum performance, follow these steps:

1. Use cold water—the colder the better. Ice water or partially frozen water is recommended.
2. Hold the generator at approximately 45° whilst filling.
3. Once filled, quickly install the regulator.
4. Gently rotate or swirl the bottle to ensure the contents mix thoroughly. Avoid vigorous shaking.
5. Place the generator into a bucket of hot water (freshly boiled water is ideal).
6. The initial reaction will charge the system to approximately 20–30%.
7. Once the water cools, replace it with fresh hot water.
8. The generator should reach full operating pressure within 3–5 hours.

Cleaning

After each refill cycle, add a small amount of white vinegar to the bottle before rinsing. This helps dissolve any residue or build-up, making cleaning quick and simple.

The Science Behind CO₂ Enrichment

Carbon dioxide is one of the essential ingredients required for photosynthesis. During this natural process, plants absorb CO₂ and convert light energy into sugars that fuel growth, flowering and fruit production.

Ambient outdoor air typically contains around 400ppm of CO₂. However, under controlled indoor growing conditions, increasing concentrations to between 1,000–1,200ppm allows plants to photosynthesise more efficiently, resulting in significantly improved growth rates and larger harvests.

Benefits of CO₂ Enrichment

Increased Photosynthesis

Higher CO₂ concentrations allow plants to convert more light into energy, promoting stronger and faster growth.

Larger Harvests

Improved photosynthesis leads directly to increased biomass and significantly higher yields.

Superior Crop Quality

Plants grown with elevated CO₂ often produce:

• Denser flowers
• Increased trichome production
• Greater resin development
• Improved potency and overall quality

Faster Crop Cycles

Accelerated plant growth can reduce the overall cultivation time, allowing more harvests throughout the year.

Best Practice for CO₂ Growing

Monitor CO₂ Levels

Use a reliable CO₂ controller or monitor to maintain concentrations between 1,000–1,200ppm. Avoid exceeding 1,500ppm, as higher concentrations provide diminishing returns and may present health risks.

Maintain Proper Airflow

Ensure your grow room has effective air circulation so CO₂ is distributed evenly across the entire canopy.

Optimise Temperature

For maximum efficiency, maintain grow room temperatures between 28–32°C, particularly when using LED lighting. This helps keep leaf temperatures above 24°C, allowing stomata to function efficiently.

Adjust Plant Nutrition

Plants growing under elevated CO₂ levels have an increased metabolic rate and generally require higher nutrient strength (EC) to support accelerated growth.

Use During Light Cycles Only

CO₂ enrichment should only be supplied whilst grow lights are operating. Plants do not utilise additional CO₂ during darkness, so running the system overnight is unnecessary.

Safety

Always follow manufacturer instructions when operating CO₂ equipment.

For safe operation:

• Ensure adequate ventilation.
• Use approved CO₂ monitoring equipment.
• Install a CO₂ alarm where appropriate.
• Follow all recommended handling and storage guidelines.
