Question

What type of plants can be grown without soil?

Answer

Hydroponic plants or aquatic plants can be grown without soil. They require water as their growing medium instead.

In this context, it's essential to distinguish between hydroponics and aquatic plants since they have different growth requirements.

Hydroponic plants are those that are grown in nutrient-rich water rather than soil. These plants do not necessarily need light conditions similar to aquarium plants but still rely on specific nutrients being present in the water. Some examples include lettuce, tomatoes, cucumbers, and strawberries.

Aquatic plants, on the other hand, are plants that naturally thrive underwater in bodies of water like ponds, lakes, rivers, etc. Examples of these types of plants would be water lilies, lotus flowers, duckweed, or even certain species of grasses found along river banks. Most aquatic plants require sunlight for photosynthesis due to living submerged in water where natural sunlight penetration is often limited.
