The science of hydroponics proves that soil isn't required for plant growth but the elements, minerals and nutrients that soil contains are. Soil is simply the holder of the nutrients, a place where the plant roots traditionally live and a base of support for the plant structure.
In hydroponics you provide the exact nutrients your plants need, so they can develop and grow. The hydroponic nutrients are fed directly at the root base, never stressing the plant due to lack of nutrients or water.
Virtually any plant will grow hydroponically, but some will do better than others. Hydroponic growing is ideal for fruit bearing crops such as tomatoes, cucumbers and peppers, leafy crops, like lettuce and herbs and flowing plants. Most hobby hydroponic gardeners plant crops similar to what they would grow in a soil garden.
Most commercial hydroponic growers combine hydroponic technology with a controlled environment to achieve the highest quality produce. Within a green house structure you can control the ambient temperature, humidity and grow light levels allowing you to grow on a year- round basis. Listed below are some general hydroponic systems and typically used.
