What is Hydroponics?

Growing plants without soil is called hydroponics, which involves using mineral nutrient solutions in a watery solution. Plants grow in soil because they get all the required nutrients, minerals and water from the soil. They also get support to stand in the soil. If the needed support, nutrients, minerals and water can be provided to a plant externally, it can grow without the soil. This project demonstrates the growth of a plant in a beaker (without soil) in which all the nutrients essential for a plant’s growth are provided.

You Require:

-One jar or bottle of 1000cc, one small plant, powder of calcium nitrate (about one gram), potassium nitrate (0.2 gm), magnesium sulphate (100mg), Urea (0.2 gm), water (1000cc).


-Take one bottle of one liter capacity and fill it with one liter of water.

-Mix about 1gm of calcium nitrate, 0.2 gm of potassium nitrate, 0.2 gm of magnesium sulphate, 0.2 gm of urea and 100 gm of iron. Dissolve all these salts properly in the bottle of water.

-Put a plant in this mixture. You can give a support to the plant by tying a thread with the neck of the breaker or putting a card board disc with a hole.

The plant will grow in this solution just as in the soil because it gets all the essential nutrients required for its growth from the solution.
