| Carbon Dioxide (CO2) Keep Your Plants Growing!
Carbon Dioxide in the air supplies all of the Carbon content in the plant. Plants breathe in Oxygen and breathe out Carbon Dioxide. During the hours of daylight plant needs Carbon Dioxide and uses this to produce sugars. It will breathe out Carbon Dioxide, during the hours of darkness which is a waste product.
The plant uses light and Carbon Dioxide for photosynthesis. A directly proportional relation has been found between CO2 required and light. The more light there is available the greater the plant’s requirement for Carbon Dioxide, It has been found that it takes about 10 photons, (quantum units of light) during photosynthesis, to create enough energy to split one Carbon Dioxide molecule into its basic components of Carbon and Oxygen and form a sugar.
Sufficient Carbon Dioxide is needed to convert their energy into sugars Because there are trillions of photons hitting the plant’s leaves, If enough CO2 is not available, then the unused photons will bounce off the plant’s leaves and be lost.
Plants absorb different spectrums of light in differing amounts. This light is affected in different ways by a range of factors, such as distance and percentage of reflection etc. It is quite complicated and difficult to calculate the level of wasted light. It can be measured using a special PAR meter (PAR = Photosynthetically Active Radiation). This machine takes into account the lumen level of the light striking the leaves and discounts the unusable fractions of the available light.
Plants in full sunlight will get about 5000 lumens/sq ft. This means that the plant could process about 2000 ppm of CO2. It is unfortunate that the Carbon Dioxide levels outside are nowhere near this level.
Indoors, the plant will need approximately 1500 ppm of CO2 if you are using a light level of 3000 lumens. This would drop to around 300 ppm CO2 if the light level was at 1000 lumens. Since CO2 in city air is about 400 ppm which is within the normal range. If the concentration of Carbon Dioxide is lower then more air has to be moved across the plant’s leaves in order for it to get sufficient exchange.
Hence if the plant has enough CO2 and enough light respectively, then we can expect a good increase in growth and subsequent yield.
