Insufficient lighting slows down the natural development of the plant. The stem of the flower becomes thinner, the new leaves do not reach their normal size, and the flower is more vulnerable to diseases and insects. The lower leaves can turn yellow and fall off (this is a popular issue for ficus and ivy).
Usually it is the color of the plant that shows that it lacks light: the flower fades or the multi-colored leaves become greener for photosynthesis. Indoor flowers that have thrown out the buds are not able to develop a full flower - they remain small and fade quickly. Excessive lighting also puts the plants under stress, even if they are well watered. In such conditions, the indoor flower may look lethargic, starting from its leaves turning yellow at the edges. If you notice such a problem, reduce the flow of light directed on your plant. Otherwise, it may dry out.
Anyway, LED lights, often used on batteries, are the optimal solution for the abovementioned problems. During their production, various factors on which the cultivation of light-cultivated plants depends, are taken into account. Moreover, LED lights ensure the process of photosynthesis and provide optimal light irradiation.
In addition to basic biological needs, the conditions of light saturation of various light cultures must be met. The main requirements for a plant are:
the length of daylight hours;
the presence of artificial light lighting;
