Photosynthesis and respiration

In nature, free oxygen is produced by the photolysis of water during oxygenic Photosynthesis. Green Algae and Cyanobacteria in marine environments provide about 70% of the free oxygen produced on earth and the rest is produced by terrestrial plants

A simplified overall formula for photosynthesis is:

6CO2 + 6H2O + Photon → C6H12O6 + 6O2 (or simply carbon dioxide + water + sunlight → glucose + dioxygen)

 

CO2 Levels

The amount of CO2 the plants can use depends on the amount of light they are receiving. The higher the light intensity, the more CO2 they can use. At normal atmospheric levels (350-400 ppm) CO2 is usually the limiting factor in indoor gardens. As the amount of CO2 in the air increases photosynthesis and the growth rate rise in a linear ratio with the CO2 enrichment.

Usually gardens using around 30 watts per square foot can handle enrichment up to about 1,000 ppm. Increasing the amount beyond that level probably won't result in increased growth, since light, the energy powering photosynthesis, becomes the limiting factor.

At 60-100 watts per square foot the plants can use 2,000 ppm CO2. (Remeber the air already has up to 450 ppm in light cycle, so only add a max of 1500ppm giving you a 50ppm buffer.) Since the amount of light the plants use for energy increases they can use more CO2, which they use as an ingredient in the manufacturing of sugar.
 
 
 Freedom is something like breathing; one only becomes acutely aware of its importance when one is choking. 
 ~William E. Simon
Importance of fresh air
  • Choking your plant life is easier then you think. Always make sure your air circulation can change the volume of air in your grow space at least every 5 min.
  • Clean air supplies oxygen which is an excellent purifier for plants. For natural growth to occur the plant must have unrestricted access to air. Plants must be allowed to grow in a natural manner for successful physiological development.
 
 
Other Benefits of Air & CO2

  1. Plants in a true aeroponic apparatus have 100% access to the CO2 concentrations ranging from 450 ppm to 780 ppm for photosynthesis. (At one mile above sea level the CO2 concentration in the air is 450 ppm during daylight. At night the CO2 level will rise to 780 ppm.) Lower elevations will have higher levels. In any case, the air culture apparatus offers ability for plants to have full access to all the available CO2 in the air for photosynthesis.Growing under lights during the evening allows aeroponics to benefit from the natural occurrence.

  2. Always make sure, if you boost CO2 levels, to turn it off during the dark cycle.

  3. There are two very cheap ways of increasing CO2 levels in your grow room. Every night at the begining of the light cycle add 1 cup of Baking Soda to a 4L water jug. Pour roughly 1-1/2 to 2 cups of vinegar, shake vigourously and leave just behind an oscillating fan. Repeat every day.

  4. Brew wine, or beer, just in front of the air intake. This method produces continual CO2 so the air circulation is stopped during the night cycle. If you must leave the air circulation running 24/7, simply add a second intake in the room with a small duct or window fan and put it on a timer. This method has the added bonus of having a celebratory drink when the harvest of the bumper crop is done.
