CO2Gro 12L DIY CO2 Generation System with Solenoid for Grow Rooms

Maximise plant growth, yield, and quality with the CO2Gro 12L DIY CO2 Generation System, available at Holland Horticulture. Designed for indoor growers looking to enhance photosynthesis, this system delivers high-purity CO2 to accelerate plant development during both vegetative and flowering stages.

Boost Growth with CO2 Enrichment

CO2 enrichment is one of the most effective methods for increasing plant performance. By raising carbon dioxide levels in your grow space, plants can photosynthesise more efficiently, resulting in faster growth, larger biomass, and improved overall yield.

While ambient air contains around 400ppm CO2, optimised grow environments typically operate between 1,000–1,200ppm, allowing fruiting and flowering plants to reach their full genetic potential.

Complete DIY CO2 Generation System

The CO2Gro 12L system includes everything needed to begin CO2 enrichment in your grow room:

• CO2 Generator Bottle
• Power Adaptor
• Solenoid Bubble Counter & Regulator
• Dry Filter with Media
• CO2 Tubing
• Funnel
• Instruction Manual

The system works by combining two separate materials (sold separately) which react to produce high-purity CO2 once activated.

Precision Control with Solenoid Regulation

Equipped with a solenoid-controlled bubble counter and pressure regulator, this system allows precise adjustment of CO2 output. When connected to a CO2 controller, growers gain full automation and environmental control over CO2 levels throughout the light cycle.

The Science Behind CO2 Enrichment

Carbon dioxide is essential for photosynthesis, the process that allows plants to convert light into energy. Increasing CO2 availability enhances this process, enabling plants to produce more sugars, grow faster, and develop stronger structural mass.

Optimal CO2 levels in indoor grow environments typically range from 1,000–1,200ppm, significantly higher than natural atmospheric levels. When managed correctly, this leads to improved growth efficiency and higher-quality harvests.

Key Benefits of CO2 Enrichment

• Increased photosynthesis and faster plant growth
• Higher yields and improved biomass production
• Enhanced crop quality, density, and potency
• Shorter growth cycles for faster harvests

Best Practice for CO2 Growing

For best results, CO2 should be used during the light cycle (12–18 hours daily) when photosynthesis is active. Maintain grow room temperatures between 28–32°C and ensure adequate airflow to distribute CO2 evenly throughout the environment.

When using LED lighting systems, increased CO2 levels may require higher EC feeding to support accelerated plant metabolism.

Always monitor CO2 levels carefully and avoid exceeding 1,500ppm to ensure both plant safety and grower wellbeing.
