Question

Plants with larger roots can be cultivated with which of the following types of hydroponics?
A. Nutrient film technique
B. Ebb and flow system
C. Drip system
D. None of the above

Answer 1

Hint:
Hydroponics is a method of growing plants in nutrient-rich water without the support of soil. Several crops, vegetables, and flowering plants can be grown with this technique. Nutrients are passed through roots differently depending on the type of hydroponic system, oxygen is supplied, pH levels are controlled, and sufficient light is provided to enable photosynthesis. Artificial lighting is used where natural light is not available.

Complete step by step answer:
The Ebb and flow system contains a closed sub-irrigation system and an elevated benching system. Water pumps into the tray containing plants. The required amount of water is absorbed by plant roots and the remaining water drains into the reservoir again. This method is helpful for potted flowering plants and short-living seedlings. Plants such as strawberries, lettuce, and tomato can be grown with this system.
The drip system is almost similar to an Ebb and flow system, but nutrient-rich water is carried by small tubes and drips directly on the top of plants. This method is used for plants with less developed root systems. Onions, peas, and cucumbers can be grown with this system.
The nutrient film technique is a hydroponic technique that does not require any medium. Plant roots are bathed in nutrient-rich water and the excess water is collected again and reused. Plants with larger roots can be grown with this method. Lemons, orchids, basil, and many other plants can be grown.

Option ‘A’ is correct

Note:
 Hydroponics technique is helpful when there is a scarcity of water. One can get organic and disease-free plants with this method. But it is important to choose the proper method of hydroponics for the plants we are growing.
