Orchids are classified into three categories based on their lighting requirements: low, medium, and high light orchids. The key to growing healthy orchids is to understand their lighting requirements and provide the necessary light intensity. A foot candle is a standard unit of measurement for light intensity, defined as the amount of light cast by a candle from one foot away. This unit is used to quantify the lighting requirements of orchids. Cattleya orchids, in particular, are known for their high light requirements, with a suggested light intensity of 3,000 foot-candles, although some sources recommend a range of 3,000 to 4,000 foot-candles. Providing the right amount of light is crucial to promote flowering and healthy leaf development in Cattleya orchids.

Cattleya orchids require 3,000-4,000 foot candles
Orchids are classified into three categories based on their lighting requirements: low, medium, and high light orchids. The amount of light an orchid receives is critical to its growth and flowering. Light provides the energy for photosynthesis, the process by which orchids convert carbon dioxide and water into sugars and oxygen.
Cattleya orchids are considered high-light orchids and require 3,000-4,000 foot candles to thrive. Foot candles, a common unit of measurement for light intensity, refer to the amount of light cast by a candle from one foot away. While Cattleya orchids require a significant amount of light, it is important to note that excessive light can also cause leaf scorch, unsightly brown spots, and reduced capacity for photosynthesis. Therefore, it is crucial to carefully manage light intensity for good plant growth.
There are several ways to measure foot candles, including using a light meter or a camera. A light meter is a straightforward method but may require purchasing additional equipment. Alternatively, most SLR cameras have built-in light meters and can be used with a plain white piece of paper and a calculator to approximate foot candles in a specific area.
Cattleya orchids, also known as corsage orchids, are prized for their large, long-lasting, and colourful blooms. They are considered intermediate growers and prefer daytime temperatures between 70°-85°F (21°-29°C). These orchids do not require a winter rest, and watering can be done year-round, allowing for a continuous display of vibrant flowers.
In summary, Cattleya orchids require 3,000-4,000 foot candles to flourish, making them high-light orchids. This lighting requirement is essential to consider, along with temperature and watering needs, to successfully grow and bloom these classic favourites.

They are high-intensity light orchids
Cattleya orchids, also known as corsage orchids or the queen of orchids, are high-intensity light orchids. They are known for their bold, bright flowers that come in a wide variety of shapes, colours, and fragrances. The key to growing healthy cattleya orchids is to provide them with bright, indirect light and appropriate temperatures.
Cattleya orchids typically grow attached to other plants, such as tree branches, and require bright, indirect light to thrive. When grown indoors, they should be placed near a window with an abundance of bright, natural light. An east- or west-facing window is ideal, as it provides indirect light and protects the plant from harsh midday sun. If the plant is exposed to direct sunlight, its leaves may turn yellow or get scorched. To prevent this, a sheer curtain can be used to diffuse the light.
Cattleya orchids have high light requirements compared to other orchids. They need sufficient lighting to bloom and produce flowers. The recommended range of light intensity for cattleya orchids is between 3000 and 4000 foot candles, which can be achieved through natural light or artificial lighting. Artificial lighting, such as LEDs, is a dependable alternative for growers who may not have access to sunny windowsills. It allows for consistent lighting regulation and can support a broader collection of orchids.
To determine if a cattleya orchid is receiving enough light, growers can observe the colour of its leaves. Healthy leaves should be a bright, light green colour. Darker foliage indicates insufficient light, while leaves that are too light or yellowish may indicate excessive light exposure.
In addition to light, cattleya orchids require appropriate temperatures to grow well. They prefer daytime temperatures between 70° and 85°F (21°-29°C) and nighttime temperatures between 55° and 60°F (13°-15.6°C). Providing a 10-degree temperature difference between day and night is ideal for the plant's growth.

Use a light meter to measure foot candles
Light plays a crucial role in orchid growth and flowering. It provides the energy for photosynthesis, influencing nearly all aspects of an orchid's development. The intensity of light is typically measured in foot candles, which is the amount of light cast by a candle from one foot away. For example, if an orchid requires 1500 foot candles, it would take 1500 candles placed one foot from the plant to provide sufficient light.
To measure foot candles, you can use a light meter, which is the most accurate method. Light meters can be purchased for around $100 to $300. When using a light meter, follow these steps:
- Place the light meter at the same height as the orchid leaves. For Cattleya and Dendrobium orchids, the recommended height is 6 to 12 inches above the leaves.
- Ensure the light meter is positioned directly under the light source to get an accurate reading.
- Adjust the light source's height or intensity until the desired foot-candle level is achieved. For Cattleya orchids, the recommended range is 3000 to 4000 foot candles.
- Take measurements at different times of the day, as light intensity can vary throughout the day due to changes in natural light conditions.
- Repeat the process regularly to ensure consistent lighting conditions for your orchids.
It is important to note that LED light meters may not always provide accurate readings for orchid care. This is because they are calibrated to measure visible light for humans, which is mostly in the green spectrum. Orchids, depending on their growth stage, require varying amounts of red, green, and blue light. As an alternative to a light meter, you can use a PAR (Photosynthetically Active Radiation) meter, which takes into account the different light spectrums utilized by plants.
Additionally, there are other methods to measure light intensity. You can use a camera with a built-in light meter, which requires a plain white piece of paper and a calculator. You can also download light meter apps on your phone, which can be free or low-cost. While these methods may be more convenient, they may not provide the same level of accuracy as a dedicated light meter.

Artificial lights are a good alternative
Light is essential for blooming orchids, and Cattleyas are considered intermediate growers with high light requirements. While they need bright light, it is important to manage the light intensity carefully, as both low and high light levels can negatively impact the growth and appearance of orchids.
To measure the light in your growing area, you can use a light meter or your camera if it is an SLR camera. Most SLR cameras have a built-in light meter and, with some instructions, can help you determine the light levels. This method can help you avoid purchasing additional equipment.
Artificial lights can also be used to extend the photoperiod or day length. A small amount of light, about 10 foot-candles, is required to create a long day. This can be achieved with one 60-watt incandescent or one 15-watt compact fluorescent lamp placed every 5 to 6 feet apart. However, it is important to note that this amount of light is not sufficient for plant growth but rather to create a long photoperiod.
When using artificial lights, it is crucial to manage the light intensity to avoid scorching the leaves or causing unsightly spots on the orchid. Excessive light can also cause flower abnormalities. The suggested maximum light intensity for Cattleya orchids is 3,000 foot-candles, while other orchid varieties, such as Zygopetalum, should not exceed 2,500 foot-candles.

Light affects all aspects of orchid growth
Light is the most important factor when it comes to growing orchids. Providing the right light for orchids is essential for photosynthesis, the process plants use to make food from carbon dioxide and water. The proper light also makes flowering possible.
The light requirements for orchids can be classified into three categories: low, medium, and high light. While many orchids can tolerate lighting outside their recommended ranges, it may be at the expense of their flowers. Cattleyas, for instance, are known for their high light requirements. They need bright light and appropriate temperatures to bloom and grow. They are considered intermediate growers, with daytime temperatures ranging from 70°F to 85°F (21°C to 29°C).
The intensity of light, or its strength, is one of the key considerations when providing light for orchids. If the light isn't strong enough, the orchid won't be able to produce enough energy for flowers. The plant will be weak, with thin and long leaves. On the other hand, too much light will cause leaf sunburn, reducing the surface area for photosynthesis. The ideal light intensity will enable the orchid to convert carbon dioxide and water into energy, resulting in strong, light-colored leaves.
The duration of light, or photoperiod, is another important factor. Orchids grown outdoors or in a greenhouse will naturally get the full spectrum of light needed. However, for orchids grown indoors, light duration becomes a crucial consideration. Timers can be used to automate light duration, ensuring consistency and providing the orchids with the necessary night and day cycles.
The quality of light, or its colour, is also significant. While many orchids only require a sufficient quantity of light, some orchids, like Cattleyas, need bright light. For optimal blooming results, the light spectrum should mimic sunlight. This can be achieved with full-spectrum bulbs, which provide light in the blue and red spectrum. LED lights have become popular for orchid growing as they can be tailored to the specific needs of the orchid.
