Question

Which of the following is not used in hydroponics?
(A) Aerating tube
(B) Soil
(C) Organic matter
(D) Both (B) and (C)​

Answer 1

Both (B) and (C)​ that is Aerating tubes and soil are not used in hydroponics.

Explanation:

1. Hydroponics is the process used for growing plants through organic matter.
2. In such type of growing methods a nutrient-rich water-based solution is used to grow the plants.
3. No such soil, manure anything is needed.
4. The roots of such plants are supported by perlite, clay pellets rock wool, etc.
5. Therefore, Aerating tubes and soil are not used in hydroponics.

Answer 2

(D) Both (B) and (C)​is not used in hydroponics

Explanation:

1.Components of the aeration system are essential for proper oxygenation and circulation of nutrients of the hydroponic system. It facilitates faster growth and hence healthier plants.

2. It renders a constant oxygen supply along with a constant supply in the nutrition reservoir which ensures that nutrients do not settle thats aerting tube is necessary for hydroponics.

3.Hydroponics, also called aquaculture, nutriculture, soilless culture, or tank farming, the cultivation of plants in nutrient-enriched water, with or without the mechanical support of an inert medium such as sand, gravel, or perlite.

4.For example, The hanging gardens of Babylon, the floating gardens of the Aztecs of Mexico, and those of the Chinese are examples of Hydroponic culture.
