Customers love it for its maximum light output—some dubbing it as their “little ball of sunshine”—and although this does require some installation know-how, the results are worth it.

How we chose the best orchid grow lights

The biggest task a grow light needs to accomplish is providing enough light intensity and spectrum for orchid growth. So weighing wattage, color temperature, and lifespan were crucial in our considerations.

We wanted to make sure the grow lights had ample power, but we didn’t want all the options to run up your electric bill. So, we also included models that had adjustable wattage or low-power consumption. Design and function were also taken into account. Indoor gardening can be a complex hobby, so we wanted to find models with features like built-in timers, easy installation, and adjustable settings. 

Who this orchid grow light is for

Anyone who is currently growing (or dreaming of growing) orchids indoors can benefit from grow light as they’ll give your flowers the best chance at blooming success. However, they’re especially helpful for those living in northern climates without tons of natural sunlight, as well as people living in apartments with limited outdoor space.

What to know before you buy a grow light for orchids

Technically, you can put orchids in the corner—but that doesn’t mean you should. While these hardy flowers are designed to survive in low-lighting conditions, they’ll only reach their full flowering potential if they’re kept in an area with sufficient grow light. You don’t have to be an indoor gardening pro, but getting a handle on things like wattage, light spectrum, and longevity can help you choose the right grow light for your orchids.

Types of grow lights

You can’t just pop your old desk lamp from high school over your orchid and expect to grow a healthy plant. Different variants of these flowers require different intensities of light. Rather than being at the mercy of the sun and its naturally fickle nature, grow lights and grow lamps allow you to simulate particular light spectrum and intensity levels, giving your orchid the exact nourishment it needs.

Fluorescent

Surprisingly enough, the same bulbs that light up your refrigerator can be great grow lights for orchids. Not only are they affordable and easy to find, but they’re also great at evenly distributing light across a wide area (which prevents leaf sunburn). Just make sure to look for bulbs with a color rendering index or CRI of at least 85 and a color temperature (measured in Kelvin) that falls between 5,000 and 6,000 K.

High-pressure sodium

High-pressure sodium grow lights (also called HPSs) are good at providing intense lighting in a relatively small space. They emit a yellowish hue—think the streetlights that line your local roads—which actually encourages blooming. However, they do also tend to result in some pretty leggy plants, but there are ways to minimize this effect. They also tend to be more expensive.

Light-emitting diodes

Probably the most popular grow light for orchids, light-emitting diodes (also called LEDs) are extremely efficient—especially when they’re full-spectrum. This means they fully resemble natural sunlight, which is obviously key for photosynthesis. LEDs are also more energy efficient and don’t give off as much heat, which can cause your orchids heat stress. The only downside is that LEDs are not really regulated, and many manufacturers falsely advertise their lights as full spectrum.

Wattage

Ideally, you’ll want a bulb that’s capable of providing around 40-50 watts. You can use a single bulb or multiple to create the amount you need. The higher, the more intense it will be. 

Where you’ll be placing your bulb also matters. A grow light placed close to your orchid will require less wattage, but one placed at a farther distance may need more in order to provide the same amount of energy. Lay out your setup in advance and calculate your grow light’s wattage needs accordingly. 

Light spectrum

Wattage determines a light’s power and intensity. But the quality? That’s dictated by its spectrum. Outside under the sun, plants naturally get exposed to the full spectrum of light. Placing your orchid inside won’t give it that same chance, which is why you have to substitute it with grow lights. 

Whatever type of light you choose, it should be full-spectrum. This means it should possess all of the visible spectrum of light, including UV and IR. Most models will be labeled as such, but you can also look for an 85+ CRI and a color temperature range between 5,000-6,500 K. 

Longevity

On average, your grow lights will be shining down on your orchids at least 12-15 hours per day. Installing a timer helps, but the only way to ensure you’re not replacing bulbs every couple of months is to buy grow lights that are built to last.

Fluorescents have the shortest lifespan, usually lasting between 7,000 and 15,000 hours, while HPSs won’t burn out for at least 25,000 hours. When it comes to longevity, LEDs are your best bet, as they can run for a whopping 200,000 hours—which is almost 23 years of continuous use.

The advantages of owning a grow lights for your orchid

Grow lights are beneficial to orchids and their owners alike. As anyone who has ever tried “raising” one before will tell you, these flowers are finicky and hard to please. Any equipment you can use to optimize their care is worth its weight in gold—and grow lights are no exception.

Their biggest advantage is, of course, having full control over the light intensity and spectrum your orchid receives. No more second-guessing the amount of sun coming through your window or worrying about inclement weather stunting blooms. In fact, growing orchids under grow lights actually facilitates more blooming so that you can enjoy those gorgeous colors more often.

And finally, grow lights expand the type of orchids you can cultivate. Many indoor gardeners have found that they can experiment with new varieties like miniature Cattleyas and Dendrobiums that would otherwise grow too slowly under natural sunlight. More orchids and more blooms? Sounds like a win-win to us.

• They give you full control over your orchid’s lighting.
• They facilitate more blooms.
• They allow you to cultivate more varieties of orchids.

With absolute pampering, your orchids can live for a long time.

Tips for using grow lights

Part of what makes grow lights so alluring to orchid cultivators is the ease they bring into the equation. But like any equipment, grow lights must be used correctly to reap the rewards. Burning out too quickly is really the biggest threat they face. Installing a light timer prevents them (and your flowers) from overheating. 

You should also keep your grow light distance in check. The best grow light setup is when the bulb is placed at an appropriate distance from your orchids—not too close, not too far. Research what your specific orchid variant requires, but 12 inches is a safe starting point.

If you’re cultivating blooms that require a lot of light, you can easily double what your grow lights are giving off by strategically placing a mirror around the grow light fixture. This helps reflect more light back onto your orchids and ensures they can soak up as much of it as possible. 

• Use a light timer to prevent premature bulb burnout.
• Place your grow light at least 12 inches away from your orchid’s leaves.
• Use a mirror to double the amount of light your orchid gets, if necessary.
