Refill packs available here. 

Growing with CO2 enrichment is a proven method for boosting yields, improving quality, and accelerating growth. By providing your plants with optimal levels of carbon dioxide during the vegetative and flowering stages, you can harness the power of photosynthesis to achieve impressive results!

Each Generator comes with:
-CO2 Generator Bottle
-Power Adaptor
-Solenoid Bubble Counter
-Filter (With Dry Filter Media)
-CO2 Tubing
-Funnel
-Instruction Manual

This CO2 generator works using mixing two materials (Material A + Material B sold separately) which once charged will generate high-purity CO2!  Then simply adjust the pressure-reducing valve to your desired output and plug it into a CO2 controller for full control over your CO2 Levels!

** HOW TO PROPERLY FILL YOUR CANNISTERS **

1. Make sure to use cold water – the colder the better! Use crushed ice water or part frozen if you want.
2. Hold it at 45 degrees when filling once it’s full put gauge in quick
3. Swizzle / rotate the bottle at 45 degrees (don’t shake it like a bloody cocktail!) Try to swish the bottom bits around
4. Then dunk the cannister in a bucket of hot ass water – boil some water ideally.
5. This will charge to 20-30% , then once water has cooled, stick it in more hot water again (use boiled water). This will then charge up within 3 to 5 hours
6. Cleaning the bottle between usage – adding a small amount of vinegar inside will break any caking left inside the bottle making cleaning very very easy. 

The Science of CO2 Enrichment

Carbon dioxide (CO2) is a critical component in the process of photosynthesis, the biochemical pathway that allows plants to convert light energy into chemical energy, which is stored as sugars and other organic compounds. During photosynthesis, plants absorb carbon dioxide from the air and use it to produce glucose and oxygen. When CO2 levels are elevated, plants can perform photosynthesis at a faster rate, leading to increased growth and yield.

In a controlled indoor cultivation environment, maintaining an ideal CO2 concentration is essential for maximizing plant growth. Typically, outdoor air contains around 400 parts per million (ppm) of CO2, but fruiting plants especially can benefit from higher levels, ideally between 1,000 and 1,200 ppm. By increasing CO2 concentrations in the cultivation area, growers can optimize photosynthesis and, in turn, enhance the plant’s development.

Benefits of Growing with CO2

1. Increased Photosynthesis: As mentioned earlier, elevated CO2 levels stimulate photosynthesis, allowing plants to capture more light energy and convert it into biomass. This leads to faster growth and larger, healthier plants.
2. Enhanced Yield: A direct result of increased photosynthesis is higher yields. Growers who implement CO2 enrichment can expect more bountiful harvests, ultimately increasing their profitability.
3. Improved Quality: Not only does CO2 enrichment boost quantity, but it also enhances the quality of the crop. Plants grown with higher CO2 levels often produce denser buds, increased trichome production, and improved potency.
4. Faster Growth Cycle: CO2 enrichment can shorten the time it takes for plants to reach maturity. This can be particularly advantageous for commercial growers looking to optimize their production cycles.

 Implementing CO2 Enrichment

1. Monitoring and Control: Accurate monitoring of CO2 levels is crucial. Use a reliable CO2 monitor or controller to maintain the desired concentration. Aim for a range between 1,000 and 1,200 ppm, but be cautious not to exceed 1,500 ppm, as higher levels can lead to diminishing returns and potential health risks for growers.
2. Proper Ventilation: To ensure that CO2 is distributed evenly throughout the growing area, you’ll need efficient ventilation and airflow systems. This helps prevent pockets of stagnant air and ensures all plants receive the benefits of CO2 enrichment.
3. Ensure that grow room temperatures are kept between 28-32 degrees C, especially when growing with LED lights this will help ensure the leaf temperature is kept above 24 degrees. This consistent temperature will enable the leaf’s stomata to transpire correctly.
4. Feeding plants grown under LED lighting using CO2 will need higher EC levels due to the plant’s increased metabolism.
5. Timing: CO2 enrichment should be implemented during the light period of the plant’s growth cycle. Typically, this means providing CO2 for 12-18 hours a day when the lights are on. Monitoring and controlling CO2 levels during the dark cycle is unnecessary and wasteful.
6. Safety Measures: Safety should always be a top priority when working with CO2. Ensure proper ventilation, use certified equipment, and follow manufacturer guidelines for CO2 storage and handling. A dedicated CO2 monitor and alarm system can provide an added layer of security.
