What Is The Evolution CO2 Bottled Gas Regulator?

The Evolution CO2 Bottled Gas Regulator works to regulate the flow of CO2 for any compatible CO2 bottle. This solenoid controlled regulator is aimed at anyone wishing to maintain the levels of available CO2 in your grow room. CO2 helps plants to photosynthesise, and stimulate plant growth. With a fixed flow rate of 17 litres per minute, it is the ideal bottled gas regulator for use with TrolMaster Hydro-X controller and TrolMaster CO2 Sensors.

Why Do Plants Need CO2?

While the lights are on, plants grown in grow rooms need a regular, fresh supply of CO2 to enable them to photosynthesise. To allow fast-growing plants to develop at the rate you want them to in your greenhouse or grow room, you'll need to maintain a minumum level of atmospherically available CO2. The minimum level they need is around 400ppm.

If you don't supply fresh CO2 laden air into your grow room, the plants can't grow. They can absorb all the available CO2 in less than an hour. Without a continuous supply of fresh CO2, photosynthesis slows, preventing further development. This is why using an Evolution CO2 Bottled Gas Regulator to supply fresh CO2 to your plants is a great idea.

Increasing CO2 Levels When the Temperature Rises

When the heat of summer arrives, your indoor plants can suffer from heat stress. You can help to avoid it by enriching the grow room or greenhouse with higher levels of CO2. With more available CO2, the plants can better deal with the temperature by increasing their rate of photosynthesis. This increases dramatically with an increase in temperature, resulting in a higher “optimum” temperature for photosynthesis.

How Does The Evolution CO2 Bottled Gas Regulator Work?

The Regulator is connected to your CO2 bottle and wired into your chosen CO2 controller. The Evolution CO2 Bottled Gas Regulator is extremely reliable and simple to set up and use.

Garden tip: The ambient atmospheric levels of CO2 are around 300-400ppm.
