Most plant enthusiasts are facing a problem of flower cultivation, that is, the indoor light is insufficient, and some friends have no light on the balcony of their homes. If the indoor light is not turned on, it will be black. Can this situation be used for flower cultivation? Not every family has a lot of light. Are there any plants that do not need light to grow?
Plants that can grow without light basically do not exist. Most plants grow with more or less light, whether natural or light.
However, some plants can grow in completely dark environment for two or three weeks, such as ornamental taro, tiger tail orchid and leaf orchid, and can not grow in completely dark environment for a long time, otherwise they will wither.
1. Can plants survive without sunlight?
Of course not! No indoor plant grows in darkness. Plants need proper light to survive. In a completely dark environment, it doesn't take long for plants to hang up.
If you want to keep plants indoors without light, you can supplement the lighting, such as the following shade-tolerant plants, such as white palm, peacock, taro and green radish, can give 10 to 12 hours of light every day (there is no natural light during the day), but also maintain the normal growth of plants.
2. What happens when plants don't have sunlight?
If plants do not grow in enough light, they will grow elongated. The elongation means that the spacing of leaves is enlarged. The stems and leaves grow very long and tender, but this is equivalent to the growth of seedlings and looks very delicate. Slowly the plant's stems and leaves lose their color, become dark and even transparent.
If there is a light source near the plant, they will tilt towards the place where there is light. This is the phototaxis of the plant.
However, most of the rooms will have some natural light, even if the lights are not turned on at night, there will be other light sources in the city's rooms.
Then these rooms can have some plants that can adapt to the low light environment, such as common bamboo turtleback, sunflower, fern, nest fern, tiger tail orchid, cymbidium, Millennium tree and leaf orchid, etc.
3. The Function of Plant Lamp
Some friends want to grow flowers when the light is not good at home, or if they want to grow flowering plants indoors, they will think of buying some plant lights. The plant lights have a certain effect on the light supplement of plants. They can even make some self-made plant lights, in fact, to ensure that the light source is adequate.
Plant lights can't be turned on all the time. Every day, plants should have a completely dark environment of about 8 to 12 hours. Otherwise, plants can't get a good dormancy, which is not very good.
