Terrarium Lighthing – When thinking about the fascinating microcosm of a terrarium, the question that naturally follows is, do terrariums need sunlight? The answer echoes a broader question: do plants need sunlight? The nature and number of plants inside determine the amount and type of light required. As a rule, all terrarium lighting – sunlight or artificial. But remember, too much direct or harsh light could singe your lovely green oasis.
Terrariums need sunlight to survive, but not direct sunlight. Direct sunlight can burn the plants in a terrarium, so it is best to place your terrarium in a spot that receives bright, indirect sunlight. If you do not have a sunny spot in your home, you can use artificial light to provide sunlight for your terrarium.
Deducing the terrarium lighting needs might seem straightforward (you’ll see why in a moment), yet it is a delicate balancing act. Each plant species within your terrarium has unique light requirements, and the secret lies in understanding them. With a multitude of terrariums, it may not be feasible to employ the same light settings for each, especially when relying on sunlight. This is where terrarium lights and the concept of artificial lighting come to the rescue.
In the journey ahead, we’ll walk you through the intriguing world of terrarium lighting, from sunlight basics to the low light terrarium plants, and everything in between. So sit tight and let’s illuminate our understanding!

Sunlight Basics for Terrariums
Terrarium plants generally thrive under natural light, a.k.a sunlight. However, if not monitored and moderated, this very sunlight could transform into a grim reaper for your terrarium flora. The lighting needs of different plants vary, with some basking in bright light, while others preferring a shady retreat.
Luckily, addressing the lighting needs of a terrarium isn’t rocket science. A little research about your terrarium plants, and you’re good to go. But, what if you’re unsure about the plant species inside?
For such a scenario, indirect sunlight serves as the most neutral and safe option. Most plants (excluding mosses) prosper under such conditions, offering a simple lighting solution for your terrarium.
Plant Categories and Their Illumination Needs
Grouping plants based on their light requirements needn’t be as stringent or complex as some might suggest. Majority of terrarium plants exhibit versatility, blooming under a range of conditions provided they’re not extreme.
For instance, succulents. These plants thrive under low humidity and high light conditions. Placing them in a closed terrarium alongside a moss terrarium under the same terrarium light might prove detrimental. And, the reverse is true as well.
While I could extend this article into a hundred pages discussing each plant’s specific light needs, it would be overwhelmingly detailed and potentially unhelpful. It’s best to adhere to the basics, research your plants, and let your creativity run wild!
Positioning Your Terrarium
Terrarium placement is often overthought, but in reality, it is a rather straightforward process. Here are a couple of suggestions that I follow:
- For a few terrariums receiving ample sunlight, position them near a window for daily indirect light.
- If you have several terrariums or receive limited sunlight, consider incorporating artificial terrarium lighting and setting up a dedicated terrarium stand.
The above advice can be easily modified according to your specific needs, the types of plants you are growing, and your local climate and light conditions.
In essence, terrarium light needs vary based on the plants within, but most can flourish under bright, indirect sunlight. If your collection expands or you’re limited by sunlight, that’s when terrarium grow lights come into play. The key is not to overthink it, observe, adapt and enjoy the process of building your next terrarium!
Understanding Artificial Terrarium Lights
As we’ve established, sunlight is a great natural source of light for your terrarium, but what happens when you have insufficient sunlight or an ever-growing collection of terrariums? This is where artificial terrarium lighting, or terrarium grow lights, steps in to save the day.
Artificial terrarium lights are not just substitutes for natural sunlight; they can be tailor-made to suit specific light requirements of your terrarium plants. These lights allow you to control the intensity and duration of light exposure, offering a flexible and convenient lighting solution.
From LED lights to fluorescent bulbs, the market offers a myriad of options to cater to your terrarium lighting needs. LEDs, with their low energy consumption and long lifespan, have become a popular choice. Fluorescent bulbs, on the other hand, are favored for their cooler operating temperatures and broad spectrum light output.
Remember, the key to using artificial lights effectively is to mimic the natural day and night cycle. Keeping your lights on for about 12 hours and off for the rest is a good starting point.
Low Light Terrarium Plants
When considering plants for your terrarium, it’s important to bear in mind their light requirements. Many plants survive and thrive under low light conditions, making them ideal for indoor terrariums. These low light terrarium plants can adapt well to both natural and artificial lighting.
Here are some favorites that flourish in low light:
- Ferns: Ferns, such as the maidenhair or button fern, are classic terrarium plants that do well in low light and high humidity conditions.
- Mosses: Mosses, like sheet or cushion moss, create beautiful green carpets in terrariums and thrive under low light.
- Creeping Fig: This plant is a vigorous climber and quickly covers the terrarium floor and walls.
- Prayer Plant: With its vibrant leaves that fold up at night (as if in prayer), this plant adds a unique touch to your terrarium.
- Baby’s Tears: This plant forms a dense, bright green mat and thrives in a humid, low light environment.
By choosing low light terrarium plants, you’re not only adding to the visual appeal of your terrarium but also ensuring that your plants survive and grow in optimal conditions. Whether you’re using sunlight or terrarium lights, your choices will have a significant impact on your terrarium’s success.
Last Notes
Ultimately, your terrarium lighting requirements depend on the number and type of plants you house. From low light terrarium plants to those requiring bright light, there’s a wide spectrum to consider. Whether it’s sunlight, a plant light for terrarium, or artificial terrarium lighting, the right balance can help your little garden thrive. As with most things in life, the golden rule is to avoid extremes and stick to moderation. With these tips in your arsenal, you’re well-equipped to light up the life in your terrarium!
