Light is one of the most significant climatic variables that affect a plant's development, along with CO2, temperature, humidity, and other variables. It is a necessary component for photosynthesis to occur, and it is directly dependent upon it for the plant to produce organic matter from mineral materials. Photosynthesis, the process by which a plant produces organic matter for growth and development, requires light as its energy source.
You must provide proper illumination if you want to achieve optimal crop development and increased output, as photosynthetic activity and efficiency improve with light, temperature, and CO2. Plant development is accelerated and photosynthesis is more efficient at greater light levels. However, photosynthesis can only go so quickly before reaching a limit as light intensity rises. The "light saturation point" is this maximum, beyond which the pace of the physicochemical process of photosynthesis falls flat.
Two primary criteria will determine how much light the plant receives: its intensity and the number of hours it receives each day. The term "photoperiod" refers to the fluctuations in light that plants experience. Depending on the species, different exposure times or hours of light are required for crop development and blooming.
All plants require light to survive, and very few do so below a certain threshold. For plants, however, too much or too little light might be detrimental. Insufficient light causes plants to grow less vegetatively, bloom less frequently, weaken, and generate smaller leaves. However, excessive light exposure can also lead plants to develop chlorosis, which is the yellowing of leaf tissue brought on by a deficiency of chlorophyll.
