Can sunlight be carried out by plants under fluorescent light?
The spectrum of a fluorescent lamp contains a band of photosynthetically active radiation, so it can be used by plants for photosynthesis. In general, the three primary daylight lamp has the same photosynthetic efficiency as 73% of the sun under the same illuminance. That is, 10000Lux illuminance of daylight light, approximately equivalent to about 7300Lux of sunlight. Most plants need 10000-40000Lux sunshine. The lights light up, considering the economy, can be designed for about 20000Lux, and extend the illumination time (20 hours / day). Philips 21W T5 straight tube three primary fluorescent lamp, luminous flux is about 1900Lm; if the light utilization rate is 50%, then the effective luminous flux is 950Lm. If there are 1 square meters area of plants, to achieve 20000Lux illuminance, you need 20000/950=21 lights, the total power 21x21=441W. The distance between the tube and the plant should be kept at 30-50cm. Further away, the illumination decreased sharply and there was no effect. Such illuminance can be converted into sunlight, which is equivalent to 15% of the direct sunshine in the summer, or 25% of the direct sunlight in the winter.
Yes, just a little slower than in the sun. Just a few more lights
Use lights to fill a plant, is considering the spectrum, the two is to consider the strength of the light.The spectrum of a fluorescent lamp contains a band of photosynthetically active radiation, so it can be used by plants for photosynthesis.
