The Pros and Cons of Going Hydroponic Hydroponics is a Latin term, which literally means “working water.” What it means to horticulture is the growing of plants without soil. Hydroponic gardening is an exciting field that offers solutions to several problems faced in the world of food production. The plant roots are suspended within the water by various designs and the crop obtains the food nutrients directly from the water, or from an air mist sprayed directly unto the plant roots. Hydroponics also requires the use growing media. Hydroponic systems use various mediums that are composed from relatively inert materials that have the ability to retain the food rich moisture and have the ability to physically support the plant roots. Many people who grow their hydroponic plants in a greenhouse will also find that they need the correct amount of carbon dioxide in the air in order for their plants to flourish. The addition of carbon dioxide in these small spaces can be accomplished in several ways. Burning hydrocarbon fuels, the use of dry ice, fermentation, decomposition of organic matter and the use of compressed bottled carbon dioxide can create the correct atmosphere for your plants to grow in. 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. Educators have also begun to realize the amazing applications that hydroponics can have in the classroom. Many gardeners have made their dreams come true by making their living in their backyard greenhouse and selling their produce to local restaurants and markets. The potential of hydroponic culture is incredible, but commercial hydroponics in the United States was held back until hydroponic systems that were economical to build and relatively easy to operate became available in the marketplace. The first thing any hydroponic gardener needs is a dedicated area for their gardening. Most newbie gardeners can either purchase an easy to install grow room or build a greenhouse outside of their home. Small grow rooms for the beginning hydroponic gardener are usually slightly larger than a closet and can be completely installed in under an hour.
