It is possible to grow plants without light by employing hydroponics. Hydroponic systems allow plants to be grown without the need for soil, as they get all the nutrients they require from a nutrient-rich water solution. It is usually applied directly to the roots of the plants, enabling them to grow without the need for photosynthesis.
However, they won’t grow as well and can exhibit odd growth patterns or lower yields than they would in the presence of light. Light is vital to plant growth because it triggers many physiological processes, including the synthesis of chlorophyll and the process by which plants absorb light.
