Match the hydroponic systems with their correct descriptions: Ebb and Flow, Drip System, Wick System, NFT, Aeroponics, Aggregate Culture, Water Culture.

• Ebb and Flow - A technique of flooding and draining an absorbent media, Drip System - Involves systems that use an absorbent media, Wick System - A system that absorbs the solution through capillary action, NFT - Most popular water-based system, Aeroponics - Involves misting of the plant roots, Aggregate Culture - Conserves the most nutrient solution, Water Culture - Does not require an absorbent media

• Ebb and Flow - Does not require an absorbent media, Drip System - Involves systems that use an absorbent media, Wick System - A system that absorbs the solution through capillary action, NFT - Most popular water-based system, Aeroponics - Involves misting of the plant roots, Aggregate Culture - Conserves the most nutrient solution, Water Culture - A technique of flooding and draining an absorbent media

The electrical conductivity of the nutrient solution in a hydroponic system will determine the:

• pH of the solution.

• Nutrient content of the solution.

• Ions in solution.

• All of the above.

Tap water in a hydroponic system:

• Contains salts that affect its electro-conductivity.

• Has a pH that will vary depending on where you live.

• Contains few, if any, nutrients required for plant health.

• All of the above.

Which of the following is not a media used in hydroponics?

• Perlite

• Rockwool

• Vermiculite

• Mineral Soil

The pH of a nutrient solution

• does not matter.

• determines the amount of nutrients that will be absorbed.

• measures the amount of nitrates in the solution.

• All of the above

What is the main reason for using a water pump in hydroponic systems?

• To aerate the water

• To circulate the nutrient solution

• To increase water temperature

• To filter out contaminants

In hydroponic systems, why is it important to monitor the pH level of the nutrient solution?

• To ensure the water is safe to drink

• To control the growth rate of plants

• To optimize nutrient uptake by plants

• To prevent the solution from freezing
