CO2Gro 12L DIY CO2 Generation System (With Solenoid)

Enhance your plant growth with the power of CO2 enrichment! Using carbon dioxide during the vegetative and flowering stages can significantly boost yields, improve quality, and accelerate growth. By optimizing CO2 levels, you can supercharge photosynthesis and achieve outstanding results.

What’s Included in the Kit:

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

This system generates high-purity CO2 by combining two components (Material A + Material B, sold separately). Once charged, the generator produces CO2 for your plants. Simply adjust the pressure-reducing valve to your desired output and connect it to a CO2 controller for complete regulation of your CO2 levels.

The Science Behind CO2 Enrichment

Carbon dioxide is vital for photosynthesis, the process plants use to convert light into energy. Elevated CO2 levels enhance this process, enabling plants to grow faster, produce higher yields, and develop superior quality. While natural outdoor air contains approximately 400 ppm of CO2, indoor cultivation benefits from higher concentrations, typically between 1,000 and 1,200 ppm.

By increasing CO2 levels in your grow area, you maximize photosynthesis and support robust plant growth.

Why Use CO2 Enrichment?

1. Boosted Photosynthesis: Higher CO2 levels enable plants to absorb more light energy, resulting in accelerated growth and stronger plants.
2. Higher Yields: Faster photosynthesis translates to increased harvests, improving overall profitability.
3. Enhanced Crop Quality: Expect denser buds, better trichome production, and higher potency from your plants.
4. Shorter Growth Cycles: CO2 enrichment reduces the time to maturity, ideal for commercial operations aiming for efficiency.

How to Implement CO2 Enrichment

1. Monitor & Control: Use a CO2 monitor to maintain levels between 1,000–1,200 ppm. Avoid exceeding 1,500 ppm to prevent diminishing returns and potential safety risks.
2. Proper Ventilation: Ensure even CO2 distribution with adequate airflow, avoiding stagnant pockets of air.
3. Maintain Optimal Temperatures: Keep grow room temperatures between 28-32°C, especially with LED lighting, to maintain proper stomatal transpiration.
4. Adjust Nutrient Feeding: Plants grown under LEDs with CO2 enrichment require higher EC levels due to increased metabolic activity.
5. Timing: Enrich CO2 only during the plant’s light cycle (12–18 hours daily). Avoid adding CO2 during dark periods to prevent waste.
6. Safety First: Follow proper CO2 handling guidelines, use certified equipment, and ensure good ventilation. A CO2 monitor with an alarm system is highly recommended.

Take your indoor cultivation to the next level with the CO2Gro 12L DIY CO2 Generation System—a reliable, efficient, and cost-effective way to unlock your plants’ full potential!
