Is It Possible To Grow Orchids Solely Using Artificial Light?

Orchids, like any plant, rely on sunlight for photosynthesis and can grow new leaves, spikes, and roots. They require at least 12-14 hours of light to flower and produce keikis. However, growing orchids under artificial light alone is possible with proper precautions. Full-spectrum bulbs that emit at least 2,000 lumens per square foot should be used, and the light should be maintained during daylight hours.

Orchids can be grown indoors using artificial light sources such as fluorescent bulbs, LED lighting, halide bulbs, and incandescent bulbs. Some orchids may require additional light requirements due to indoor light being insufficient. Light quality is an important factor when growing orchids under artificial light, as some windows block ultraviolet light and not all artificial light emits the correct distribution of light wavelengths.

In climates with plenty of natural sunlight and South or East-facing windows, there should be enough natural light. However, in darker climates, orchids can still grow under artificial plant light even if natural sunlight is insufficient or unavailable. Photosynthesis is universal, so any grow lights for any plant, such as cannabis lights, can be used for orchids.

Artificial light sources make it possible to grow orchids without greenhouses or bright windowsills. Phalaenopsis (moth orchids) and African violets (Streptocarpus syn Saintpaulia) can be grown under lighting successfully, and phals, being relatively low-light orchids, do well in artificial light. If a good location is not available, placing orchids under artificial lights is the last resort.

In summary, orchids can be grown indoors under artificial light if they have the necessary light and proper care.

Can you keep a plant alive with artificial light?

Low-light plants should receive between 50 and 250 foot-candles of light, while medium-light plants prefer 250 to 1, 000 foot-candles. They can be maintained at as little as 10 foot-candles under artificial light. They should receive 10 to 15 watts of fluorescent light per square foot of growing space. A single fluorescent tube provides enough light for these plants. Medium-light plants prefer 250 to 1, 000 foot-candles, and best growth occurs above 750 foot-candles unless they receive extended periods of direct sunlight.

They should receive artificial light in the 500 to 1, 000 foot-candle range or 15 or more watts per square foot of growing area. A fixture containing two fluorescent tubes is sufficient for plants in the low- to medium-light range, and adjustments can be made by regulating the distance between the tubes and plants.

Can orchids survive on artificial light?

To ensure orchid growth, use full spectrum blue and red artificial light, specifically designed for plants. Place the light a few inches away from the orchid to prevent overexposure. Provide at least 12 hours of light daily, with the preference for morning and afternoon light. LED lights are becoming popular for orchid growing due to their efficiency and variety of colors. While more expensive than traditional fluorescent lights, they can provide better light for orchid growth. Place the light a few inches away from the orchid, ensuring it is not getting too much or too little light. Most orchids prefer morning and afternoon light over evening light.

Do orchids do well under fluorescent light?

High-intensity compact fluorescent light is a newer option for growing orchids without the need for greenhouses or bright windowsills. These fixtures, similar to high-intensity-discharge (HID) units, produce little heat, reducing the likelihood of orchid burn. Artificial light sources allow for the growth of any orchid without the cost of equipment and electricity. Fluorescent lights are the most accessible and economical lighting systems, with three-tiered light carts providing 24 square feet of growing area.

These carts are versatile and practical, providing enough space for compact orchids to bloom year-round or miniatures for an entire collection. They can be placed in a heated garage, basement, or spare bedroom. Fluorescent light systems are ideal for homes lacking sufficient bright light for orchids.

Do orchids like ultraviolet light?

Ultraviolet (UV) light, which is characterized by high energy and potential harm to plants, can be advantageous when combined with additional light sources. A light source with a color temperature of 6500 kelvin provides the requisite blue light.

Can orchids live in a dark room?

Growing plants indoors is a challenge due to the lack of light and limited space, as plants need to be in a window for optimal growth. Even low-light orchids struggle without a window, as light is essential for plants. Mounted orchids cannot tolerate dryness in homes, making it impossible to grow them.

Light is crucial for plants, and the placement of plants in relation to windows can significantly impact their growth. However, lighting is also challenging for plants until an eye is developed. Plants see light for what it is, while humans adjust their surroundings to make them appear brighter. The iris of human eyes expands and contracts to allow the same amount of light into our eyes, causing us to see the same intensity/brightness regardless of the situation.

This can be seen when leaving a home in the summer, where the light is too bright, and we may shield our eyes or wear sunglasses to lower the intensity. This demonstrates how our senses can sometimes mislead us.

Can orchids grow without natural light?

Orchids require sunlight for their growth, but specific varieties need different types. Direct sunlight can damage their foliage, while too little can cause a lack of blooms or delayed flowering. Yellowing leaves can also indicate inadequate light. To enhance the display, consider growing the Areca palm or Spider plant alongside your orchids. These air-purifying plants complement your orchids, adding a tropical vibe and making them perfect for pet-friendly households.

Should orchid roots be exposed to light?

Phaenopsis orchid roots can photosynthesize, allowing them to produce chlorophyll when exposed to light. White roots lack chlorophyll, meaning they were never exposed to light. Just Add Ice grows orchids in clear pots, exposing them to light during their growth stage. The roots arrive with plump, green ones. Brown/mushy roots can indicate overwatering, which is the number one mistake indoor plant enthusiasts make. To fix this issue, remove the roots and ensure they are properly watered.

Can orchids grow in dark rooms?

Low-light orchids, such as Phalaenopsis, Paphiopedilum, and Masdevallia, prefer indirect or filtered light and can be grown in low light levels. Medium-light orchids, like Cattleya, Dendrobium, and Oncidium, require more light but not as much as high-light orchids. High-light orchids, like Vanda, Cymbidium, and Brassavola, require direct sunlight and can be grown in bright, unfiltered sunlight or under high-intensity grow lights.

Can orchids grow in a bathroom without windows?

Orchids are tropical plants that thrive in humidity and can be placed on bathroom windowsills. They prefer bright, indirect sunlight and require minimal care. Peace lilies, elegant and flowering, require minimal care and require plenty of sunshine for blooming. They thrive in low light and occasional indirect sunlight. Keep the soil moist, as they will wilt if too dry. Pothos, with long trawling vines that can grow up to 10 feet long, are another attractive hanging bathroom plant. They are virtually indestructible and can tolerate low light levels and irregular watering. Trim them if they grow too long and water them when the soil feels dry.

Can orchids be grown under grow lights?

Greenhouse lighting can be achieved using artificial plant lights or grow lights. Sunlight is the most cost-effective method, but northern climates may require additional lighting for orchids. DIY greenhouses should follow indoor lighting instructions. If installed by a company, consult with them or a reputable greenhouse supply store for plant lighting options. Photosynthesis is universal, so grow lights can be used for any plant, including cannabis lights for orchids.

What happens if you put an orchid in direct sunlight?

Sunburned orchids can cause white spots surrounded by dark rings. To protect them, use filtered light, such as a sheer curtain, and keep them in a north- or east-facing window for added protection. If access is limited, keep them several feet back in rooms with south and west-facing windows to allow diffused light. Water your orchids with three ice cubes or one quarter cup of water once a week, but they may need more hydration if the weather has been too hot in the last week.
