Hydroponic Basics
What is the method of growing plants in a water-based, nutrient-rich solution without soil?
What is Hydroponics?
What is the process by which plants convert sunlight into chemical energy?
What is Photosynthesis?
This essential nutrient is crucial for plant growth and is often the first number in a nutrient solution's N-P-K ratio.
This leafy green vegetable is commonly grown in hydroponic systems due to its short growth cycle.
What is lettuce?
One key benefit of hydroponics is the reduction of this common gardening issue caused by planting in soil.
What is soil-borne diseases?
This term describes the practice of growing plants indoors or in controlled environments using hydroponics.
Controlled Environment Agriculture
This layer of the Earth's atmosphere protects us from harmful ultraviolet radiation.
What is the ozone layer?
What term describes the mixture of water and nutrients that is delivered to plants in hydroponics?
What is nutrient solution?
What type of herbs are particularly well-suited for hydroponic cultivation due to their compact size?
What are basil and cilantro?
Why does our hydroponic system need light?
What is to trick the plants into thinking it's sunlight?
What is the primary benefit of using hydroponics compared to traditional soil gardening?
What is higher crop yield in smaller spaces?
What is the term for a species that is at risk of extinction?
What is an endangered species?
Hydroponic solutions must be regularly monitored for this measurement, which indicates the solution's acidity.
What is pH?
This fruit is one of the most popular crops grown hydroponically and can be harvested multiple times a year.
What is tomato?
Hydroponics can be more water-efficient than traditional agriculture, why?

How do plants get nutrients in a hydroponic system?
What is it is in the circulated water?
This gas, primarily produced by human activities, is a major contributor to climate change.
What is carbon dioxide (CO₂)
This micronutrient is vital for photosynthesis and is often added to hydroponic nutrient solutions.
What is magnesium?
This type of plant requires careful management in hydroponics due to its extensive root system and heavy nutrient needs.

What is a growing medium (e.g., rock wool, clay pellets)?
This system combines both aquaculture and hydroponics, utilizing fish waste to provide nutrients for the plants.
What is aquaponics?
Nitrogen is important to plants and helps them with what?
What is growth and development?
These flowering plants can thrive in hydroponic systems but require specific light conditions to bloom properly.
What are orchids?
While hydroponics can lead to higher yields, what is a problem with setting up a hydroponic system compared to planting in the garden?
What is higher start up costs?
