If you have a hydroponic growing system in place, then you will be needing hydroponic nutrients. hydroponic nutrient is plant fertilizer, and because the plants are growing without soil, it is imperative that you provide the plants with all the food they need through the hydroponic fertilizer that you use in the system. Organic nutrients suitable for hydroponic gardening are the best way to go, especially if you are growing vegetables and fruits.

These hydroponic nutrients are made without the use of synthetic chemicals, which can be toxic to humans and animals, and thus offer a safer choice for growing food crops in your hydroponic growing system. In hydroponic gardening, the organic nutrients are used as a liquid fertilizer, because the plant food is mixed into water to form a solution. In deep water culture, the plant roots stay submerged in the hydroponic nutrient solution, and are aerated by a submersible pump and air stones.

In ebb and flow hydroponics, plants are grown in a soilless growing medium in a tray with a reservoir holding the organic nutrients solution below, and then periodically a submersible pump raises the liquid level so it floods into the plant tray, after which the fluid leaks back into the reservoir. In aeroponics, which uses no growing medium at all, the crowns of the plants rest in nets that hold the roots of the plants in the air. A mister is used to spray the hydroponic fertilizer on the plants roots, and in this way the plants receive both food and needed oxygen for optimal growth. Organic nutrients have been specially formulated for certain types of plants, certain stages of plant growth or for overall plant nutrition.

Some organic nutrients are especially suited for growing wonderful fruits and flowers, and could contain ingredients such as bone meal, rock phosphate, cottonseed meal and other organic fertilizers. Some of the nutrients are used on a regular basis to supply the plant with food, while others are used as boosters, to the supply the plant's special needs at certain times, like the bloom booster fertilizer. Whichever nutrient you choose, it will also need to include both macro and micronutrients. These nutrients must all be present in order for the plants to survive and in the right amounts in order for them to thrive. Some nutrient is formulated to produce short, squat plants that have thick, strong stems. Others are blended to bring out vivid colors in flower and fruit production. There are organic nutrients available to meet any hydroponic fertilizer need your plants might have.
