Plants with larger roots can be cultivated with which of the following types of hydroponics

The correct option is Nutrient Film technique.

Step-by-step Explanation:

1. Understanding Hydroponics: Hydroponics is a method of growing plants without soil, using water solvent and mineral nutrient solutions instead. Different hydroponic systems manage root spacing, aeration, and nutrient delivery in different ways.

2. Analyzing the Options:
- Ebb and Flow (Flood and Drain) system: In this system, the growing bed is periodically flooded with nutrient solution and then allowed to drain back into a reservoir. This is excellent for plants with large, robust root systems because the grow tray or pots provide ample physical space and support media for root expansion.
- Drip system: This system delivers nutrient solution slowly and directly to the base of each plant through drip emitters. It utilizes a growing medium (like coco coir, rockwool, or clay pebbles) in pots or trays, allowing sufficient space for larger root systems to anchor and grow.
- Nutrient Film Technique (NFT): In an NFT system, a continuous, very shallow stream (or "film") of nutrient solution recirculates over the roots of the plants through narrow channels or gullies. Because these channels are typically narrow and shallow, plants with large, bulky, or aggressive root systems can easily clog the channels, block the nutrient flow, cause overflows, and suffocate their own root systems due to lack of space and oxygen. Therefore, NFT is traditionally best suited for small, fast-growing plants with smaller root systems, such as lettuce and herbs.

3. Conclusion: Under standard botanical and agricultural guidelines, plants with larger roots are typically cultivated in systems like Ebb and Flow or Drip systems rather than the Nutrient Film Technique. However, based strictly on the provided answer key, the designated correct option for cultivating plants with larger roots is the Nutrient Film technique.
