We’ll discuss the different types of terrariums, their pros and cons, what supplies are needed, how much maintenance they require, and more. So whether you’re searching for an eye-catching display piece or a lush garden sanctuary, this comprehensive guide will ensure you find exactly what you’re looking for. Let’s dive in!


What are the different types of terrariums?

There are three main types of terrariums: open, closed, and semi-closed. Open terrariums don’t have a lid, so they need to be located in areas with low humidity and away from direct sunlight; these are best for succulent arrangements and cacti. Closed terrariums have a lid that prevents excess evaporation, making them ideal for growing tropical plants such as ferns, mosses, and air plants. Semi-closed terrariums have a mesh top or partially opaque lid that allows some ventilation but still maintains an environment suitable for humid loving plants.


What kind of lights do I need for my terrarium?

It depends on the type of plants you’re growing. Most plants require some sunlight but direct sunlight can be too strong for terrariums, so you may need to invest in artificial lighting. For open terrariums, an LED grow light or fluorescent bulb should suffice. Closed terrariums will need a more powerful light source such as a high-output LED or metal halide.


What are the materials used to construct terrariums?

Terrariums come in a variety of materials including glass, plastic, and acrylic. Glass is the most popular material because it provides excellent visibility and insulation; however, it can be heavy and breakable if not handled carefully. Plastic is lightweight and shatterproof but tends to yellow over time with exposure to UV rays; acrylic is a sturdy, shatterproof option but it’s not as transparent as glass.


How much does a terrarium cost?

The cost of a terrarium will depend on the size and material; generally speaking, smaller terrariums can be purchased for $20-$50 while larger ones may cost up to $500 or more. Additionally, you’ll need to factor in any necessary lighting equipment and other supplies such as potting soil, gravel, plants, etc., which could add anywhere from $30 – $200+ to your total bill.


What kind of maintenance do terrariums require?

Terrarium maintenance depends on the type; open terrariums typically require more frequent watering and pruning since there’s no lid to retain moisture. Closed terrariums can go weeks without needing water as long as you don’t open the lid too often. Semi-closed terrariums usually require moderate levels of care, such as occasional misting or light fertilization.


Can I use my terrarium as part of a home décor display?

Absolutely! A well-designed terrarium can make an excellent addition to just about any room in your house. You can also mix and match different plants and materials to create unique displays that will capture the attention of anyone who visits your home.


Are terrariums safe for pets?

It depends on the type of pet. Open terrariums are generally safe for most animals as long as they can’t reach any of the plants inside. Closed and semi-closed terrariums may pose a choking hazard to small animals, so it’s best to keep them away if you have pets in your home.


What kind of plants work best in terrariums?

Terrariums are ideal for growing low-maintenance, humidity-loving plants such as ferns, mosses, succulents, air plants, etc. Generally speaking, you should choose plants that thrive in humid environments and don’t require too much sunlight or fertilizer.


How often should I water my terrarium?

It depends on the type of plants you’re growing and the type of terrarium; open terrariums typically need to be watered once a week or so, while closed and semi-closed terrariums may not need any additional water for several weeks. It’s important to monitor your plants closely and adjust accordingly.


Are there any other tips for maintaining a healthy terrarium?

Absolutely! In addition to regular watering, you should also check your plants periodically for pests or disease, make sure they’re getting enough light (artificial lighting can help in this case), and prune them regularly to promote healthy growth. Additionally, adding some gravel at the bottom of your terrarium can help with drainage and air circulation.


Terrariums are an excellent way to bring some life into your home without too much effort or maintenance. They’re relatively low-cost, come in a variety of sizes and materials, and provide a great opportunity for creativity when it comes to design. Whether you want a simple display or something more complex, there’s sure to be a terrarium that fits your home and lifestyle.
