How to Use more CO2 to Boost Hydroponic Plant Growth
Carbon dioxide is needed in a hydroponic garden to guarantee continued plant growth because it is required for photosynthesis. Many gardeners do not realize that the larger their hydroponic garden is, the more their plants need carbon dioxide for respiration.
How can you boost the carbon dioxide content in your hydroponic garden? There are five ways that you can increase the level of carbon dioxide in your greenhouse to increase plant growth. First, the burning hydrocarbon fuels will create carbon dioxide gas. Second, the use of dry ice can aid in the production of this gas. Third, fermentation of organic materials creates carbon dioxide. Fourth, the decomposition of organic matter such as compost will create carbon dioxide. Finally, the use of compressed bottled carbon dioxide is the most commonly used way to create the gas in a greenhouse for the desired effect.
Large greenhouses have burned hydrocarbon fuels for years in an effort to increase growth in their plants. Examples of hydrocarbon fuels are propane, butane, natural gas and alcohol. Fuels that contain sulfur or sulfur compounds cannot be used because they produce harmful by products when they burn.
Dry ice can be used in small greenhouses, especially if a cooling effect is also desired. Dry ice, which is solid carbon dioxide, is effective when used in a well-sealed area. The ice can either be used in block form or broken down into small pieces and used a little at a time. Another method is to put the dry ice into a Styrofoam container with holes in it to slow down the rate of evaporation. Since carbon dioxide is heavier than air it must be placed above the plants in order for it to drift down and surround the plants.
Fermentation is another way to create more carbon dioxide in your hydroponic greenhouse. This method is easy to accomplish with few materials
