This is an advantageous method of gardening for home and for commercial use. There are no weeds to deal with and hydroponic plants are typically healthier, mature earlier, and use less space. Hydroponic plants are entirely water based which makes it possible to fully automate the hydroponics system. Specially formulated hydroponic fertilizer mixtures are required and should be tested after dilution to ensure a pH level of between five and six. The most popular method of generating carbon dioxide for your hydroponic plants is the use of a pressurized carbon dioxide system. The equipment is relatively inexpensive (under $500) and the operating expense is low. In addition this system does not generate heat so it is easier to regulate than other forms of generating carbon dioxide. The energy saving poly greenhouse covers, the PVC pipe used in the feed systems, and the nutrient injector pumps & reservoir tanks were all made of types of plastic not available prior to the 1970s. As both small and large hydroponic farms were established in the late 1970s, it was proven that hydroponic culture could produce premium produce and be a profitable venture. Quick Results for your Hydroponic Veggies and Flowers Have you ever wanted a garden that would produce beautiful flowers and delicious fruits year ‘round? You can if you create a hydroponic garden in your home. A well-balanced nutrient solution for your hydroponic garden is the key to success. The nutrient solution circulates around the roots of your plant and the formula will either make your plants happy and fruitful or kill them. Many hydroponic gardeners use a method of natural prevention called “companion planting.” In companion planting crops are intermixed with plants that act as spider mite deterrents for the primary crop. For example, marigolds may be planted between rows of herbs in a hydroponic greenhouse. Different types of artificial lighting are selected for specific plant varieties and optimum plant growth characteristics. In hydroponics, nutrient solutions are used to feed plants instead of using plain water. This is due to the fact that the plants are not grown in soil. When growing hydroponically, the gardener will need to add all of the nutrients the plant needs to the water.
