SFT: Hydroponics Quiz

Which plants are hard to grow hydroponically?

• 
• 
• 
• 

Answer explanation

Root vegetables are difficult to grow hydroponically because they require a large space for their roots to expand, which is challenging in most hydroponic systems.

Why do hydroponic plants typically require less space to grow compared to traditional soil-based farming?

• Hydroponic plants are smaller than soil - based plants, taking up less space.

• Hydroponic plants grow taller than soil-based plants, which reduces the need for horizontal space.

• Hydroponics allows plants to be grown vertically or in stacked layers.

Answer explanation

Hydroponic systems provide nutrients directly to the plants, eliminating the need for large root structures and enabling space-efficient growth.

Why do hydroponic plants often taste better than traditionally grown plants?

• They absorb nutrients more efficiently, leading to better flavour.

• They are washed in sugar water before being sold.

• Hydroponic plants are genetically modified for better taste.

• They grow slower, which makes them sweeter.

Answer explanation

Because they’re given a precise amount of nutrients they require, they grow faster and reach peak ripeness more efficiently.

How does hydroponic farming help reduce food waste in supply chains?

• Hydroponic farms are usually closer to consumers, meaning fresher produce with less spoilage.

• Hydroponic produce is indestructible and never goes bad.

• Hydroponic farms require more middlemen to distribute the produce since they are harder to access.

• Hydroponic farming increases transportation costs because the produce is heavier than soil-grown crops.

Answer explanation

Hydroponic farms can be located within urban areas, reducing the time and distance needed to transport food. Since the produce reaches consumers faster, it stays fresher for longer, leading to less waste compared to traditional farming, where long transportation times can cause spoilage.

How does hydroponic farming impact biodiversity?

• It helps protect natural ecosystems by reducing the need for deforestation and land use.

• It eliminates all types of plant and animal biodiversity.

• It requires large amounts of land, reducing biodiversity.

•  It introduces invasive species that harm local wildlife.

Answer explanation

Traditional farming requires large areas of land, often leading to deforestation and habitat destruction. Hydroponic farming, however, can be done in smaller, controlled spaces like greenhouses or vertical farms.
