Maximise the yield from your grow space with high average PAR intensity
Indoor growers want to maximise the yield from their grow area. Increasing the amount of light their plants receive by increasing PAR Intensity can help growers achieve this goal. To make the most of the high PAR intensity we recommend running a closed environment with increased CO2 at about 1,200 ppm but it is not essential.
Our ARAY 4X4 High PAR CO2 fixture will deliver an average PAR intensity of about 1,326 µmols/m²/second which will maximise the potential yield from a 4ft x 4ft or 1.2m x 1.2m space with or without elevated CO2.
How much does added CO₂ increase growth rate?
The normal atmospheric CO₂ level is 370 parts per million (PPM). The best way to achieve this level in your grow room is to draw fresh air from atmosphere into your grow room at a high rate. It is recommended you change the air in your grow room frequently with the use of an extract fan and ducting drawing fresh air into the grow room. At these rates you will maintain very close to atmospheric levels of CO₂ of 370 PPM and achieve good growth. With this setup it is not practical to achieve any increase in CO₂ in the grow room. This is because any CO₂ added to the grow room will be removed quickly with the constant air flow out of the grow room.
If you want to increase CO₂ levels in the grow room you will have to seal the room so the CO₂ does not escape and use a CO₂ generator or CO₂ cylinder with a CO₂ controller and regulator. Sealing the grow room will mean you will have to manage the temperature and humidity with air conditioning. This is relatively expensive and complex and requires a significant investment in equipment and time to setup but can increase growth rate and yield by up to 30%.
Using the naturally higher CO₂ levels in the house to increase growth rate
You can also use your own CO₂. Humans expel CO₂ when breathing out so the level within our homes is often twice the concentration outside. This is most common in winter months when the air circulation in homes is minimal. It's common for CO₂ levels in the home to range from 700 -1,000 PPM. In a bedroom at night CO₂ levels may reach as high as 2,000 PPM.
