The indoor flowers fill what lights
1400 watt light bulbs are 2 meters from the plant and have the same illuminance as daylight. If the distance of illumination is shortened, the intensity of illumination used can be reduced by the inverse law of the square of the distance from the plant. For the sake of economy, 100~300 watt white fluorescent lamp can also achieve certain lighting conditions to meet the growth requirements of plants. When the light source is close to the plant, it will not burn the plants. Only 10 to 12% of the incandescent light is used as light energy, and the remainder is heat energy. Plants may burn when they are near the plant.
Ordinary three primary energy-saving lamps (cold day light color) on the line, Watts as much as possible to choose a larger, 13W, 18W, 23W, 24W, these are more common high brightness energy-saving lamps, supermarkets have sold ~!
Three primary color fluorescent lamp, or color temperature 6500k fluorescent energy-saving lamp can be effective
The plant biological lamp made in recent years is more suitable for the illumination of plants. To increase the length of the sun, use an incandescent lamp to turn on the lights in the middle of the night to prevent the plants from forming flower buds during the long dark periods. Incandescence has a long wave of red light and is most effective in stopping the dark. Light is usually added from 20~2 in the evening, and it can destroy the accumulation of flowering substances during dark periods.
