Question 1:

What is hydroponic gardening?

Click to see Hint ⬇
Hydroponic gardening does not involve traditional soil.
Click to see Answer ⬇
Growing plants without soil - Hydroponic gardening is a method of growing plants without soil, using nutrient-rich water solutions instead.

Question 2:

Which of the following is a common hydroponic system?

Click to see Hint ⬇
This hydroponic system involves a mist environment for plant roots.
Click to see Answer ⬇
Aeroponics - Aeroponics is a hydroponic system where plant roots are suspended in an air/mist environment and nutrient solution is applied in the form of a mist.

Question 3:

What is the primary advantage of hydroponic gardening?

Click to see Hint ⬇
One of the main benefits is related to water consumption.
Click to see Answer ⬇
Reduced water usage - Hydroponic systems are designed to use water more efficiently, leading to reduced water consumption.

Question 4:

What is the purpose of a nutrient solution in hydroponic gardening?

Click to see Hint ⬇
The nutrient solution plays a vital role in providing something essential to the plants.
Click to see Answer ⬇
To supply essential nutrients to plants - In hydroponic gardening, the nutrient solution serves as the primary source of essential nutrients for plant growth, as there is no soil to provide these nutrients.

Question 5:

What is a commonly used growing medium in hydroponic systems?

Click to see Hint ⬇
This growing medium is derived from coconut husks.
Click to see Answer ⬇
Coconut coir - Coconut coir, derived from coconut husks, is a popular growing medium in hydroponic systems as it provides good water retention and aeration for plant roots.

Question 6:

What is the optimal pH range for a hydroponic nutrient solution?

Click to see Hint ⬇
The pH range is slightly acidic for hydroponic nutrient solutions.
Click to see Answer ⬇
pH 5-6 - Maintaining the correct pH level in hydroponic systems ensures that essential nutrients are readily available to the plants.

Question 7:

Which essential nutrient is often deficient in a hydroponic system, leading to yellowing of leaves?

Click to see Hint ⬇
This nutrient is essential for chlorophyll production.
Click to see Answer ⬇
Iron - Iron is crucial for chlorophyll production, and its deficiency can result in yellowing of leaves, a common symptom in hydroponic plants.

Question 8:

Which type of hydroponic system involves plants growing directly in a nutrient solution without a growing medium?

Click to see Hint ⬇
This system involves direct contact between roots and the nutrient solution.
Click to see Answer ⬇
Deep Water Culture - In Deep Water Culture, plants are suspended over a reservoir of nutrient solution, allowing their roots to grow directly in the solution.

Question 9:

What is the primary purpose of an air stone in a hydroponic system?

Click to see Hint ⬇
It is related to root respiration and growth.
Click to see Answer ⬇
Providing oxygen to the roots - The air stone creates bubbles in the nutrient solution, ensuring that the roots receive sufficient oxygen for respiration.

Question 10:

What is the recommended temperature range for a hydroponic nutrient solution?

Click to see Hint ⬇
The range is conducive to nutrient uptake and microbial activity.
Click to see Answer ⬇
20-25°C - Maintaining the nutrient solution within this temperature range promotes efficient nutrient uptake by plants and beneficial microbial activity.

Question 11:

What is the ideal relative humidity for a hydroponic grow room?

Click to see Hint ⬇
Consider the moisture requirements of plants in a controlled environment.
Click to see Answer ⬇
60-70% - A relative humidity of 60-70% is ideal for hydroponic gardening as it promotes healthy plant growth and helps prevent issues like mold and mildew.

Question 12:

What is the purpose of an EC meter in hydroponic gardening?

Click to see Hint ⬇
It is used to ensure the right balance of essential elements for plant growth.
Click to see Answer ⬇
Assessing nutrient concentration - An EC meter measures the electrical conductivity of a solution, providing valuable information about the nutrient concentration in hydroponic systems.

Question 13:

Which nutrient deficiency is indicated by interveinal chlorosis in hydroponically grown plants?

Click to see Hint ⬇
Consider the specific symptoms associated with different nutrient deficiencies.
Click to see Answer ⬇
Magnesium - Interveinal chlorosis, where the veins of the leaves remain green while the interveinal areas turn yellow, is a classic symptom of magnesium deficiency in hydroponic plants.

Question 14:

What is the recommended ppm (parts per million) range for a hydroponic nutrient solution?

Click to see Hint ⬇
Consider the concentration of nutrients in the solution.
Click to see Answer ⬇
600-800 ppm - Maintaining a ppm range of 600-800 ensures that plants receive adequate nutrients without risking nutrient imbalances or toxicities.

Question 15:

What is the role of a reverse osmosis system in hydroponic gardening?

Click to see Hint ⬇
Consider the water purification aspect of hydroponic systems.
Click to see Answer ⬇
Filtering out pathogens - Reverse osmosis systems help ensure the purity and safety of the water used in hydroponic systems by removing harmful pathogens and impurities.
