How much light do orchids need?

Different species of orchids have different requirements for their light conditions. The most popular orchid species in this country are usually among those that can get by with somewhat less light.

You can divide the different types of orchids into three categories:

  • Orchid species that can cope with less light – these least tolerate the blazing sun. In summer, it is best to place them in front of an east or west window. It is advisable to protect the plants from strong sunlight with the help of blinds, pleated blinds, or curtains when placing them on the west window. Phalaenopsis, Paphiopedilum and Miltionopsis belong to this category. They are most comfortable in a brightness of 10,700-21,000 lux.
  • Orchid species that need a little more light – they are a little less sensitive to direct sunlight, but it should not be too much, even for these plants. A location on the east or west window is also suitable here. They should also thrive in a south-facing window, provided they are placed far enough away from the window and are adequately protected from the blazing midday sun. Among the somewhat more light-hungry orchid species are the genera Brassia, Cattleya, and Dendrobium. These plants thrive optimally under an illuminance of 21,000-32,000 lux.
  • Orchid species that require a lot of light – A few species require particularly high light levels. These thrive best on a west-facing windowsill. They should also thrive in a south-facing window if you protect them from very strong sunlight. Example of this category are Vanda orchids. They require approximately 21,000-53,000 lux.

If you want to check the brightness at your desired orchid location, special light meters, also called lux meters, are suitable. These are inexpensive, accurate, and help you find the right location for your plants.

Symptoms of too much or too little light

Especially winter can be a problematic time for orchids, as they might be exposed to a lack of light in an unfavorably chosen location. But the burning sun in summer can also quickly become a problem for the plants.

So how can you find out if orchids are getting too little or too much light?

The easiest way is to look at the leaves of the plants. If large, brown spots with dark blue edges form on the leaves, this is often a sign of too much light. Yellow discolored leaves can also indicate a location that is too sunny.

Drooping flowers, droopy leaves, or even plant parts falling off can be an indication of too little sunlight.

You can also consider using artificial light for orchids.

Artificial light is suitable for orchid cultivation if the lamps cover the correct spectra. The lamp should provide as much light as possible in the range of photosynthetically active radiation.

Meanwhile, there are very good LED lamps, where the light color can be mapped accordingly. These are special plant LED lamps. LEDs have the additional advantage of being extremely cost-effective, power-saving and long-lasting.

What temperatures do orchids need?

Not only the right light intensity is important for good growth, but also the temperature should be adapted to the plants, because at the ideal room temperature, the different types of orchids differ in their requirements.

While the Phalaenopsis feels comfortable at a temperature between 20-25° in summer, the Miltonia only needs a room temperature of 17-22°.

In general, it should be noted that the temperature at night may be a few degrees colder than during the day. Orchids also allow lower temperatures in winter. For a detailed list of different orchid species with summer and winter temperatures, click here.

Since orchids come from a tropical climate, special attention should be paid to proper humidity. Especially in winter, it can quickly become too dry for orchids due to the heating air.

The optimal humidity for many orchid species is between 50 and 60 percent. This can be checked very easily with the help of a hygrometer.

If the humidity is too low, the plants dry out quickly and the leaves become limp. If the humidity is too high, the plants are susceptible to mold and bacteria. You can find out how to ensure optimum humidity even in winter here.
