CO 2 Carbon Dioxide Enrichment will dramatically increase the growth of green plants. This process is called photosynthesis. Plants that are receiving plenty of light and nutrients will only perform as well as the ambient level of CO 2 will allow. The ambient level of CO 2 in the earth's atmosphere is generally between 300 and 600 ppm.
Most plants receive far more water and energy in the form of sunshine than they can use.
Increasing the CO 2 in the growing area will let the plant use the excess water and energy that is stored in the leaves. This inexpensive CO 2 test kit includes one 100cc syringe, two CO 2 test tubes and instructions. Simply draw in 100 cc's of the room's air into the syringe, break the ends off a tube and insert the tube into the syringe. Next, slowly force the air through the tube. The CO 2 concentration is where the purple color stops and the white begins.
