Which fluorescent lamps are suitable for plant lighting
All representatives of the flora simply need light for a normal existence - growth, life, reproduction and the implementation of other processes natural to them. It seems that the indoor plants were a bit more fortunate, because they are located next to a natural source of light - the sun's rays. For all other cases, you can use fluorescent lamps for plants, which in their action are not inferior, and sometimes even surpass sunlight in their characteristics.
Signs of a lack of light in plants
- the lower leaves look much worse than the upper ones. They begin to turn yellow, dry out or fall off;
- if there are leaves smaller than usual, they look much paler than the rest of the foliage;
- blooming species with a lack of light can absolutely not produce flower ovaries, even under all other favorable conditions;
- decorative variegation of leaves is reduced to a minimum, and such foliage acquires a uniform green color;
- plant growth is noticeably reduced;
- internodes are narrow, and the stem is extended.
What ways can help the plant in this case? The most accessible and simple solution is to rearrange it to a more lighted place. Indoors, such places are usually located at the level of the window sill, including in the form of hanging pots. If the flower continues to wither, then you should resort to more serious measures, and without additional illumination is not enough. Replacing is easiest to produce special fluorescent lamps for growing plants. They operate quite effectively, and their cost is acceptable for any consumer. You can find similar products in almost any specialty store.
What are fluorescent lamps
By themselves, such lamps belong to the category of low-pressure mercury sources of illumination. They have the form of tubes that are made of glass. These tubes, in turn, are filled with a mixture of argon and mercury vapor. The luminous discharge of such luminaries emits the ultraviolet radiation of the spectrum, which is very suitable for additional lighting.This radiation is created by phosphorus inside the pipe, and it produces light in the visible spectrum. Electrodes located at both ends of the tubes conduct electrical voltage and cause the lamp to glow.
