Introduction
Terrariums are a fascinating way to bring a miniature ecosystem into your home. A terrarium is a small, enclosed garden or landscape that contains plants and soil. Curious How does a terrarium work? Let’s dig in.
The key to the success of a terrarium is creating a self-sustaining environment, where the plants and soil work together to create their own moisture and nutrients. A properly designed terrarium can provide an excellent learning opportunity for children, as well as being an attractive addition to your interior decor.
Definition of a Terrarium
A terrarium is essentially a mini garden enclosed in glass, plastic, or other transparent materials that allow sunlight in. This enclosure helps to create a humid environment, ideal for the growth of certain plant species.
Terrariums can range from simple designs with just one or two plants to elaborate ecosystems with multiple layers of soil and vegetation. One of the defining features of terrariums is their self-contained nature – they require very little maintenance once established.
The water cycle within the container allows moisture from plant respiration to condense on the sides of the container and return back down into the soil. This makes them perfect for people who are looking for low-maintenance indoor gardens.

Brief History of Terrariums
The history of terrariums dates back centuries ago when they were first created by botanists on long sea voyages where space was limited. The idea behind it was simple: creating an environment where plants could flourish despite limited space and resources.
In 1827, Nathaniel Bagshaw Ward invented what he called “Wardian cases”, which were essentially glass containers used for transporting exotic plants across oceans without them dying from exposure or lack of nutrients during their long journeys. This invention paved the way for its modern-day version: The Terrarium
Nowadays, we use terrariums as decorative elements in our homes and offices while still enjoying the benefits of the natural ecosystem. Modern terrariums incorporate elements such as rocks, sand, and driftwood to create a more naturalistic environment, while also adding visual interest.
Purpose of a Terrarium
Terrariums serve many purposes. They can be used to purify the air in your home or office by removing toxins and producing oxygen. They also provide a creative outlet for plant enthusiasts who want to experiment with different types of plants that may not typically thrive in their local environment.
In addition, terrariums can provide an educational opportunity for children, teaching them about ecology and the water cycle. Terrariums also make great gifts – they’re unique, long-lasting, and require very little maintenance.
The Science Behind Terrariums and How Does a terrarium work?
The Water Cycle
Terrariums are self-contained ecosystems that mimic the natural environment. One of the fundamental processes that occur in a terrarium is the water cycle. This cycle involves a continuous movement of water between various states, such as solid, liquid, and gas.
The process begins when water from soil or any other surface evaporates into the air. This moisture then condenses on cooler surfaces, such as glass or other objects in the terrarium.
Evaporation and Condensation
Evaporation occurs when water molecules absorb enough energy to break free from their liquid state and become a gas. In contrast, condensation is when these gaseous molecules lose sufficient energy to revert to their liquid form. When moist air comes into contact with cool surfaces inside a terrarium, it loses heat and releases moisture in the form of droplets.
Precipitation, Photosynthesis, Sunlight, and Carbon Cycle
Precipitation occurs when condensed vapor droplets become heavy enough to fall back onto the soil or plants below. Photosynthesis is another critical process that occurs in a terrarium with plants able to convert sunlight into energy through photosynthesis using carbon dioxide and water as reactants with oxygen given off as a by-product. Sunlight plays an important role in regulating temperature within the terrarium and supporting photosynthesis which aids plant growth thus contributing to a healthy ecosystem balance and facilitating natural carbon cycling over time through both plant respiration (CO2 release) and photosynthesis (CO2 intake).
Plants use CO2 during photosynthesis but also release it during respiration meaning they act as both carbon sources and sinks depending on what’s happening around them. Overall understanding How does a terrarium work are these processes work together provides insight into how a healthy terrarium can be established from initial setup through care routines over time for long-term success.
Building a Terrarium

Choosing the right container
When it comes to building a terrarium, choosing the right container is key. There are many different options available, including glass jars, bowls, vases, and even light bulbs. When selecting a container, it’s important to consider its size and shape.
A larger container will provide more space for plants to grow and thrive but also requires more soil and can be heavier. A smaller container is easier to handle but may limit the number of plants that can be grown.
Materials used for containers
The most common material used for terrarium containers is glass because it allows light to enter while keeping moisture inside. However, other materials such as plastic or metal can also be used as long as they’re transparent enough to allow sufficient light in. Keep in mind that the material used should not react with water or soil.
Selecting appropriate plants and soil
When selecting plants for your terrarium, it’s important to choose species that thrive in high-humidity environments since terrariums tend to hold moisture well. Some popular choices include ferns, mosses, succulents or air plants which require less water than traditional houseplants. Similarly, when choosing soil for your terrarium project make sure you select one that holds moisture well like potting mix instead of sand or garden soil which drains too quickly.
Types of plants that thrive in terrariums
In general, small leafy plants work best in terrariums since they require less space and have less extensive root systems compared with larger varieties. Some popular choices include ivies, spiderwort (Tradescantia), baby tears (Soleirolia soleirolii), fittonia (Fittonia spp.), Pilea peperomioides among others.
Soil types that work best
The type of soil used in a terrarium is crucial for its success. The soil should be well-draining since standing water can lead to root rot, but it should also be able to retain moisture over time.
A good option is a mix of potting soil, sand, and perlite. Stretch sphagnum moss or charcoal pieces can also be added for extra drainage and to keep the soil fresh.
Building a terrarium can be an excellent way to bring nature indoors while creating an eye-catching display. By focusing on container choice, plant selection, and soil type you will have all the essential elements for making a beautiful green world contained inside your glass jar or bowl!
Care and Maintenance of Terrariums
Watering Techniques
Watering a terrarium can be a bit tricky, as it is important to strike the right balance between not enough water and too much. Over-watering can cause the plants to rot, while under-watering will lead to plant death. The best technique is to use a spray bottle or watering can with a narrow spout.
This helps prevent water from pooling on top of the soil which can lead to root rot. It’s also important to note that different types of plants have different watering needs.
Succulents, for example, require less frequent watering than ferns or mosses. A good rule of thumb is to water when the soil feels dry about an inch below the surface.
How to Avoid Over-Watering or Under-Watering
The best way to avoid over-watering or under-watering your terrarium is by paying close attention to your plants and their environment. Check the moisture level in the soil regularly using a finger test or moisture meter.
Another factor that affects how often you need to water your terrarium is humidity levels. If you live in a dry climate, you may need to mist your terrarium more frequently than if you live in a humid area.
Maintaining Proper Humidity Levels
Terrariums are designed to be self-contained ecosystems that recycle their own air and water through condensation and evaporation. This means that maintaining proper humidity levels inside your terrarium is crucial for its overall health.
If you notice condensation building up on the sides of your container, this means that there is too much moisture inside the terrarium and you should remove the lid for a few hours until it dissipates. On the other hand, if there isn’t enough moisture inside your terrarium, then you should mist the plants with a spray bottle and/or add more water to the soil.
Light Requirements
Just like with watering, different types of plants have different light requirements. Some plants, such as succulents and cacti, require direct sunlight for at least six hours a day. Others, such as ferns and mosses, thrive in indirect or filtered light.
It’s important to place your terrarium in a location that receives the appropriate amount of light for your plant selection. If you notice that your plants are becoming leggy or discolored, it may be an indication that they are not receiving enough light.
Avoiding Direct Sunlight Exposure
While some plants require direct sunlight exposure, it’s important to avoid exposing your terrarium to too much direct sunlight. This can cause the temperature inside the container to rise quickly and lead to plant death or pest infestations. To avoid this problem, place your terrarium in a location where it can receive indirect or filtered sunlight.
You may also want to rotate your terrarium periodically so that all sides receive equal amounts of light exposure. By following these care and maintenance tips for your terrarium, you can create a thriving mini ecosystem that brings life and beauty into any space!
