Hydroponic tomato gardening is the science of growing tomato plants by nourishing them with the nutrient solution in water instead of soil. Tomatoes are grown indoor under light. The tomatoes grown this way are equal to or superior in flavor and nutrition than their outer soil grown counter parts. A tomato's sweetness is greatly dependent on light and temperature. The nutritional value of tomato is dependent on the nutrition the plant receives while growing and producing fruit.

The Hydroponic indoor gardening consists of a controlled environment with artificial lightening, temperature control and supplemental nutrition. Because of this controlled conditions the tomato plant can always meet the exact requirements of light, temperature, and nutrition level. This controlled condition enriches the quality of the fruit. Thus a gardener doing hydroponic tomato gardening can enjoy a continuous harvest for the whole year without sacrificing its taste and Quality.

Hydroponic gardening is a clean method of cultivation. For this reason it is recommended to start the growth of a tomato plant right from its seed stage. Bringing plants from outside source and than can increase chances of pest and disease contamination. The seedling is initially kept in a tray with a dome on it. Once the seed starts sprouting, the seedling should be exposed to a light source, metal halide or fluorescent lights for a minimum time of 12 hours per day. If the new plant is not exposed to proper sunlight or in proper time of its growth than it can cause the seedling to bolt in search of sunlight. It should also be ensured that the roots of these plants should not be exposed to the light, as this will cause damage and death to the roots and delay the plant growth. Usually around 10-14 days, leaves and roots start appearing in the hydroponic plant. After this stage the seedlings can be transplanted to their hydroponic gardens. There are several methods of cultivating tomatoes indoor.

The most common method employed for supplying water and nutrients for the Hydroponic tomato plants is drip irrigation also called as trickle irrigation. In this method the nutrients are circulated over the plant roots from a reservoir. This process is done continuously in the presence of light. This constant flow of nutrients with water allows the root of tomato plant to develop with higher yields. Hydroponic gardening is not only carried on commercial basis but also at personal level just as a hobby. There are different methods for feeding the Hydroponic tomato plants for the hobbyist. These methods are more simplified than the conventional methods. Thus one can really enjoy the nutritive value and taste of the tomatoes by doing Hydroponic Tomato Gardening.
