Plants grown in hydroponics are usually healthier than soil grown plant, because hydroponic plants are fed their exact nutritional requirements. The natural preventive measures against spider mites are used in most hydroponics systems. Many hydroponic gardeners use a method of natural prevention called “companion planting. Gardeners can give nature a helping hand while enjoying the therapeutic benefits of their garden. Gardeners will be able to watch the spectacular improvements that growing hydroponically can bring to their garden. Hydroponics has always been an ecologically sound gardening choice. It uses much less water than conventional gardening and does not erode the soil or add toxins to the environment. With the advent of high tech plastics and simpler system design, this came about in the late 1970s. 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. While it is possible to grow organic food through hydroponics, this is the exception and not the rule. Most growers used pesticides on their hydroponic crops. Though the pesticides used in hydroponics do not run-off and pollute the surrounding environment like the pesticides used on traditional fields, they are still on the plants themselves. Because of this reason, different pH levels for nutrient uptake are needed for each type of growing medium. Maintaining the proper pH level in the nutrient reservoir is most likely the single most critical factor to successful hydroponic gardening. If the pH factor goes too high or too low, the plants will not do well and will show confusing signs or nutrient deficiencies. The hydroponic systems also require less space, because the plant roots don’t have to spread and search for food and water. The small space requirement makes hydroponics perfect for limited space home gardeners. The greatest benefit to hydroponics is the ability to automate the hydroponics system with timers and remote monitoring equipment.
