Vegetables grown in greenhouses need continuous light throughout the day. For most of the plants, the duration of light exposure should be 10 hours or more. In winter, there is a need to organize additional light sources. Additional lighting in the greenhouse space is most beneficial for the seedlings.
Do not forget that additional lamps are unable to become a full-fledged substitute for natural light. Try not to block young plants with artificial light sources. Pay special attention to fluorescent lamps, because their volume can obstruct sunlight. In addition, it is necessary to keep the greenhouse cover material clean - film, glass, or polycarbonate.
In order for the process of photosynthesis of vegetable crops to take place more actively, you need to install additional lamps inside the greenhouses. If you did everything right, the yield of vegetables on your site will increase significantly.
Photosynthesis occurs due to the absorption of light by plant leaves. This process allows plants to oxygenate the space.
Each plant is individual according to its external characteristics and conditions necessary for their better growth. The lighting of the greenhouse with additional sources and the duration of exposure to light depend on the type of crops, the season and the age of the plant. The peculiarity of the growth of various crops is as follows: the plants on which fruits and flowers appear are more dependent on light than those whose leaves people use for food. Plants have a special time before flowering, during which the duration of illumination especially affects yield.
The lack of lighting in the greenhouse for any type of crops is unacceptable; in order to comply with the mandatory conditions, greenhouse owners use additional lamps. The main difficulty in organizing artificial sources is their correct choice. Modern companies have a wide range of lamps, each with certain advantages and disadvantages. The characteristics of the luminaires differ in the spectrum of colors, the price of the models and the amount of energy consumed by the device.
Until recently, many relied on the blue spectrum for vegetative growth, and the red portion was considered the most effective during maturation in the greenhouse. However, practice has shown that fruits grown in a greenhouse using this lighting method are tasteless.
Currently, there are no luminaires that match the spectrum of the sun's ray. Therefore, it is better to combine different types of lamps in greenhouses in winter.
Using the following principles will help you make a decent choice of lamps for ease of use in winter:
