For plants that like light, it will change after continuous rainy days, especially for succulent plants. Master good lighting methods to let your plants grow healthily.
The way to increase the illumination is to use light. The 1400 watt electric lamp produces the same illumination as sunlight at a distance of 2 meters from the plant. If the illumination distance is shortened, the illumination intensity can be reduced according to the inverse ratio of the square of the distance between the illumination distance and the plant. For the sake of economy, a 100-300 watt white fluorescent lamp can also be used, which can also meet certain lighting conditions and meet the growth requirements of plants; when this light source is close to plants, it will not burn plants.
Only 10-12% of incandescent light is used as light energy, and the rest is heat energy; when it is close to the plant, the plant may be burned. In recent years, the plant biological lamp is more suitable for adding light to plants. To increase the length of sunshine, incandescent lamps should be used. The lamps should be turned on in the middle of the night to prevent plants from forming flower buds in the long dark period. Incandescent light has a long wave of red light, which is most effective in interrupting dark periods. It can destroy the accumulation of flowering material in dark period. Fluorescent lamp does not have long wave of red light to prevent flower bud formation and cannot be used.
Shade with reed curtain, shade yarn, or put in shade. Planting shade trees also works.
In order to shorten the length of sunlight and block the light, black cloth, black paper, black plastic film and other materials can be used to create a dense and opaque environment.
The selection of shading materials and shading time should consider the temperature at that time. If the temperature is too high during shading, it will affect the normal growth of plants. The blackout time should be connected with the night, that is, it starts before sunrise or before sunset, so that flowers can differentiate into flower buds in the long night.
