    You can take the lights like in the greenhouse.

    It can be used to try the grow lights with red or blue lamps, and the red and blue grow lights are effective, but the premise is that the power is enough.

    Calculated with reference to the standard of cultivated seawater, 6 square centimeters corresponds to 1W (the specific data is in accordance with the seawater ATS algae screen lighting standard, this power LED illumination algae tank low-level algae grows well), the area of one meter square in the flower stand area, 20W with red and blue LED lights is enough.

    The area of one meter square, 20W with red and blue LED lights, this is the most conservative estimate based on the experience of mariculture.

    Yes, sunlight and lights are fine.

    Ordinary lights can't be put outside in the sun, if it's cloudy or winter, use a fill light.

    OK. When plants carry out photosynthesis, they mainly convert the energy in the light into biological energy and store it, and the light is actually a kind of light made by humans, in which the energy can be absorbed by the plant to complete photosynthesis, but because the temperature of the artificial light source is much lower than the temperature of the sun, there is less visible light that can be absorbed.

    Fluorescent lamps allow plants to photosynthesize. Scientific research has found that plants mainly rely on blue-green light and red-orange light for photosynthesis, which are contained in fluorescent lamp light, so plants can also photosynthesize under light. During the Chinese New Year in Guangzhou, the kumquat tree is illuminated with lights, so as to achieve the purpose of controlling the flowering and fruiting of the kumquat tree.

    However, plants grow better in sunlight.

    As long as the light source contains rays that support photosynthesis, it is fine.

    Green plants can photosynthesize under the illumination of light, but the light intensity of the light must reach a certain intensity.

    When the photosaturation point is reached, the photosynthesis decreases with the weakening of the light intensity, and when it decreases to a certain intensity, the CO2 absorbed by photosynthesis and the CO2 released by respiration are in a state of equilibrium, and the light intensity at this time is called the light compensation point, at this time, the plant can no longer carry out photosynthesis.

    Therefore, to be precise, photosynthesis can be carried out when the light intensity is above the light compensation point of the green plant under light irradiation, and photosynthesis cannot be carried out when it is lower than the light compensation point of the plant.

    Light can emit red light, blue and purple light, plants absorb photosynthesis, flower production, light irradiates plants, enhances plant photosynthesis, and early flowering.

    Yes.

    In some laboratories, there are also artificial greenhouses where artificial light sources (lights) are used to allow plants to photosynthesize.

    Plants can photosynthesize under light, and it is best to use light with a color temperature of 6500K or more (white light). Such as the use of greenhouse planting (supplemental light) and the cultivation of ornamental aquatic plants...

    Can plants photosynthesize under light?

    As long as there is light, it will do. Cloudy days have a certain penetrating power due to the light. That's it.

    Plants can photosynthesize under light, and they can do the same on cloudy days, but the intensity of light is different, and the photosynthetic efficiency is different.

    Yes, as long as the plant is healthy, it will photosynthesize in the light state, but the effect of different colors of light on the photosynthesis intensity of the plant is different; Photosynthesis in low light will also be less than in a certain range of strong light.

    Photosynthesis of plants.

    Photosynthesis refers to the process in which green plants use light energy to convert carbon dioxide and water into organic matter that stores energy and release oxygen.

    ps;There are professional grow lights! Specially designed to irradiate plants! **There are sales!

    1.Photosynthesis in most plants can only be carried out in the presence of light, and only a special group of sedum plants is to open stomata at night and synthesize sugars during the day.

    2.On cloudy days, photosynthesis is still going on, but with less intensity.

    3.Energy-saving lamps emit visible and infrared light, which can be used by plants for photosynthesis.

    4.The purpose of photosynthesis is to make plants synthesize organic matter and then convert it into energy for various physiological activities to carry out normally, it is a good process in itself, and plants may die if they cannot photosynthesize.

    5.Respiration occurs with or without light, and under normal circumstances, plants respire throughout their lives. Even during the dormant period.
