CO2GRO Pre-Weighed Refill Packs

CO2GRO Refill Pack – Single Charge for CO2GRO Generator

These refill packs contain the precise quantities of Material A and Material B required to complete one full refill (charge) of your CO2GRO Generator.

When combined inside the generator, the two materials produce a steady supply of high-purity carbon dioxide (CO₂) to enrich your growing environment. Simply charge the generator, adjust the pressure-reducing valve to your preferred output, and connect it to a compatible CO₂ controller for accurate, automated CO₂ management.

Why Use CO₂ Enrichment?

Carbon dioxide is an essential element of photosynthesis, the natural process that enables plants to convert light into energy. By increasing CO₂ levels within a controlled indoor growing environment, plants can photosynthesise more efficiently, resulting in faster growth, stronger development, and significantly improved yields.

Natural outdoor air typically contains around 400 ppm of CO₂. However, during the vegetative and flowering stages, many fruiting plants perform best when CO₂ levels are maintained between 1,000 and 1,200 ppm. Providing plants with this optimal concentration allows them to maximise light utilisation, nutrient uptake, and overall productivity.

Benefits of CO₂ Enrichment

Faster Photosynthesis

Elevated CO₂ concentrations increase the rate of photosynthesis, enabling plants to convert more light energy into healthy plant growth.

Increased Yields

Enhanced photosynthetic activity promotes larger plants and heavier harvests, helping growers achieve greater productivity and maximise returns.

Superior Crop Quality

Plants grown under optimal CO₂ conditions often develop denser flowers, increased trichome production, improved resin content, and enhanced overall quality.

Accelerated Growth

CO₂ enrichment can reduce the time required for plants to reach maturity, allowing growers to complete cultivation cycles more quickly and efficiently.

Best Practice for CO₂ Enrichment

Monitor CO₂ Levels

For optimum performance, maintain CO₂ concentrations between 1,000 and 1,200 ppm. Avoid exceeding 1,500 ppm, as higher concentrations provide little additional benefit and may present health risks. A quality CO₂ monitor or controller is strongly recommended.

Maintain Effective Airflow

Good ventilation and air circulation are essential to distribute CO₂ evenly throughout the grow room, ensuring all plants benefit from enrichment.

Optimise Grow Room Temperatures

When using LED grow lights, maintain temperatures between 28°C and 32°C. This helps keep leaf temperatures above 24°C, encouraging efficient stomatal function and maximising CO₂ uptake.

Increase Nutrient Strength

Plants grown under elevated CO₂ typically have a faster metabolism and may require higher EC nutrient levels to support accelerated growth.

Use CO₂ During the Light Cycle Only

CO₂ should only be supplied while grow lights are operating, generally for 12–18 hours per day depending on your lighting schedule. Supplying CO₂ during the dark period offers no benefit and unnecessarily wastes gas.

Prioritise Safety

Always use CO₂ equipment in accordance with the manufacturer's instructions. Ensure adequate ventilation, use certified equipment, and consider installing a dedicated CO₂ monitor and alarm for additional safety and peace of mind.

Grow Smarter with CO2GRO

The CO2GRO Refill Pack provides a simple, reliable, and cost-effective way to replenish your CO2GRO Generator and maintain optimal CO₂ levels throughout your grow cycle. Whether you're cultivating in a grow tent, grow room, or commercial facility, CO₂ enrichment can help unlock faster growth, healthier plants, improved crop quality, and increased harvests.
