Plants grow more quickly in light because they need light energy for photosynthetic processes. This does not imply that more light guarantees more growth. Certain plants are acclimated to low light levels, direct sunlight may harm their cell structure while some light-loving plants would perish in the shade because they are unable to create enough energy. Cependant, every plant needs some amount of sunlight to thrive, and no plant can be grown in total darkness.
