Hydroponics is the practice of growing plants without soil as hydroponics cultivates plants in nutrient-rich water. 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. The ideal temperature for your plants will be between 40 to 97 degrees Fahrenheit. The actual temperature for the particular plant you are growing will vary. For optimal growth, the amount of light your plants receive can be the difference between life and death. Too many lights can dry out your plants while too few can have your plants stretching desperately towards the lights. 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. Flowers and tree seedlings can also be grown using hydroponics. Hydroponic greenhouses produce millions of plant seedlings each year, which are transplanted and grown at other locations where they are later planted into soil. There are many benefits to growing your own plants in a hydroponics system. Hydroponic gardening is considered to be a clean and highly effective method for growing plants. There is less mess and less maintenance. Hydroponic gardening helps to eliminate the need for weeding and helps to cut down on diseases and pests.

These systems try not to use pumps and may rely on the use of a wicking agent to draw nutrients to the roots.
