Question

Which of the following statements is not true about hydroponics?
A. Can be misused to cultivate banned crops
B. Hydroponics plants cannot be cultivated everywhere
C. Technical knowledge required
D. Requires high investment

Answer 1

Hint:
Hydroponics is a method of cultivating plants in a solution rich in minerals and nutrients without the support of soil. Nutrients can be supplied from duck manure, fish excrement, or fertilizers. This method is helpful for growing plants in water-scarce areas. The hydroponics method can be used to cultivate vegetables, garden plants, crop plants, etc.

Complete step by step answer:
Plants can be grown anywhere using this system, whether underground, on rooftops, or in greenhouses. It is possible to grow plants in places where traditional farming is not feasible. Nutrients and water are recycled. There is no need to use fertilizers or pesticides to produce organic food.
Even though the hydroponic system has many benefits it has some limitations. To start cultivating plants with hydroponics we need high investment at the beginning. Construction or acquisition of an indoor facility with substantial space, as well as installation of the hydroponic system, are part of the initial investment. Additionally, the system is costly due to the purchase of nutrient packages, the arrangement of external water sources, the hiring of experts to monitor and control it, the cost of electricity, the purchase of backup power equipment, the purchase of monitoring equipment, and the loss of profits as a result of damaged crops.
To operate a hydroponic system one should have technical knowledge about the instrument and the operation of the system. It can also be misused to cultivate marijuana that falls under the prohibited product list.

Option ‘B’ is correct

Note:
Plant growth is limited by cold climates with chilly winter temperatures and short daylight hours. Hydroponic systems, on the other hand, allow plants to be grown hydroponically all year round because the grower controls the light, temperature, and nutrient supply.
