How is the light for orchids reasonable?

Ho Diep does not need much light, many plants grown indoors near glass windows, with little daylight can still produce cotton. The most suitable light is diffused natural light. Avoid placing it in direct sunlight.

Caring for orchids is a meticulous work, not everyone can take care of orchid baskets from childhood to adulthood and produce the first batch of flowers. The orchid lives mostly on steam from its surroundings and in suitable lighting.
Everything needs light, without light, humans and animals cannot see anything and cannot live. Orchids like other herbs, they all need light to create nutrients to nourish the plant and also thanks to the light that plants can bear fruit. Lack of light the plants will not grow and flower.

Sunshine and light We should not confuse light with sunlight. Light means that indirect sunlight does not shine directly on the tree. When you leave a tree in the shade it only has light, different from a tree that grows outdoors in direct sunlight. But both light as well as sunlight have different degrees of light, so scientists often use a plant Light intensity meter in units of candlelight (footcandles). Based on this tool, people will move the orchid to a lighter or darker place. This tool costs about 30 USD, quite cheap compared to the luminometer to take very accurate pictures but is much more expensive.

Most orchids need only medium light, but some species need at least 5-8 hours of sunlight a day to flower with different luminosities. Vanda 3000-4000 candlelight. Cymbidium 3000-3500 candlelight. Candlelight Oncidium, Dendrobium 3000. Cattleya and other species 2500-3000 candlelight Phalaenopsis, Paphiopedilum need only planted under shade or 1500-1800 candlelight. Seedling plants need 12-14 hours of light a day. The sun is divided by the time and direction of the sun as follows:

Sunshine from 6-10 am or southeast direction is very good for orchids. Sunshine from 10 am to 3 pm many species of orchids can not stand it. The sunlight from 3 to 6 pm or the Northwest direction is good, but not as good as in the morning. In addition, you should know that the sunlight in Spring or Autumn is different from the sunlight in summer. Sunshading If you grow orchids outdoors, the light will depend on sunlight and if it's too sunny, you need to shade it. One can use sparse wood, bamboo, but it is better to use nylon mesh that is both light, durable, and convenient because of the appropriate brightness of 50-70%. Mesh screens can reduce heat and come in a variety of colors: green, dark, brown and black. Remember that black is easier to catch the sun and increases the temperature. If planted in the middle of the garden, a 50% net should be used for Vanda, Dendrobium and Cymbidium species and 70% for Cattleya, Oncidium, etc.

Bright enough Looking at the leaves we can see if the orchid has enough light or not. With enough light, the orchid leaves will be greenish yellowish. Some orchids, when bright enough, the leaves have red purple. This color is the plant's sunscreen agent. When present, it means the plant is sunny enough to flower. Too sunny When you see a stunted tree growing slowly, the leaves are yellow, or have large brown spots or are bent, it means too much sunshine. Move the plant to a place with less sunlight or it will wither and die slowly. When you see the green orchid, it looks beautiful, but it is a sign of lack of light. The tree may still grow green, but it is difficult to flower. If the green leaves turn soft and weak, it is too low light the plants cannot grow.

Ho Diep has the characteristic of flowering. If you do not cut the faucet when the flower is gone, let the faucet still bloom for a while. So, if you take care of it well, the tap is big, you should leave the tap on after the flower fades, nourish the plant for a while and let the flower continue on that faucet. But it should be noted that orchids are usually very weak, if they are greedy for a long time, the plant will drown, the leaves will not be hard. Players who know how to play often cut the hose after the flower is gone, or if the plant is weak, cut the faucet sooner. Then nourish the tree with 30-10-10 fertilizer for a while so that the plant is strong again, then think about stimulating 6-30-30 to let another hose.

Ho Diep is the oldest orchid variety. When there is cotton, if you do not water the fertilizer, do not let water spray on the cotton, do not leave it in the sun, the cotton can play for up to 2 months. Man Thien Hong also has the most durable flower species.

Stemming from passion, perseverance and hard work, after 23 years of research and research on orchid growing techniques, I have accumulated a lot of experience in propagating and cultivating forest orchids effectively.
