Terrarium Concepts

Terrariums are nothing less than a miniature ecosystem of plants placed in a sealable container and are perfect for indoor spaces. They are commonly used as a decoration or substitute garden in areas with little or limited space like an office or a bedroom. They are self-sustaining which means they required little maintenance if sealed.

Beside plants, Terrariums contain their own soil, air, food, and water, everything they need to thrive. The sealed container creates a unique environment for plant growth where a small scale water cycle takes place thanks to the light and heat entering the terrarium through the transparent walls. Moisture from the soil is taken into the plant through the root system, passes through the leaves by transpiration, evaporates into the air, then condenses on the containers walls due to the limited atmosphere and finally trickles down to the soil and plants to be used again. The photosynthesis process also takes place thanks to the light entering through the glass container.

We can't forecast a terrariums life span since it's as unpredictable as life itself. If they are cared for properly, though, they can last a couple years. Some models of sealed terrariums have lasted for more than two decades. Follow your tailored CARE TIPS guide to keep them healthy.

1.����� Light: Terrariums require bright but indirect light. Do not put them in direct sunlight or outside for a long time. 2. Water: Sealed terrariums require little water, usually once a month. Depending on the container size and the terrarium model we provide a little guide with tips on frequency to water them properly. 3. Pruning: A little trimming often promotes side shoots that fill out plants. You might need to trim tips if they start to touch the container�s walls. 4. Cleaning: You might need to remove dead leaves periodically and scrub the sides of the container to prevent them from becoming moldy or remove any build ups. (Go to CARE TIPS tab for further information on terrarium maintenance)

Given their self-nourishing nature, closed terrariums need minimal care, that's why they are the perfect choice for people with a busy schedule. We do recommend, at least once a month, taking off the container lid for about 10-20 minutes to let it air out and remove excess of moisture. Follow the tips described on our CARE TIPS section to make them stay healthy and vibrant.

Mold is usually a dead giveaway that the terrarium has excess of moisture. If you experience white mold in your terrarium, chances are the water inside it might be too abundant. First thing you need to do is removing the lid off for a few days to promote air circulation and reduce humidity, following you can use a cotton swab dipped in water to remove any mold covering the plants, rocks and decorations. Don�t use the same cotton swab twice so you won�t spread the mold around. If you find it difficult to remove mold from some plants, you might want to just trim or remove the plants from the terrarium.

Yes, they do. When terrariums are closed, air is trapped. Plants in closed terrariums recycle this air, which means they use the carbon dioxide and light during the day, sunlight promotes the production of oxygen and food (sugars) through photosynthesis. Then at night they use oxygen and produce carbon dioxide.

Overwatering is the most common problem with terrariums and it generally leads to mold and bugs. Closed terrariums don't need water very often (Usually once or once every three months). As a rule of thumb, when you see condensation in your closed terrarium, there is no need to add more water. Do not allow water to sit at the bottom of the terrarium for extended periods of time as this may cause plant roots to rot. You can use paper towel to soak up excess water. Also remove the lid and place in a brighter area for a few hours (but never in direct sunlight). Regular filtered tap water, distilled water, or carbonated water can be used to water terrariums.
No. Since slow plant growth is desired in the container, the limited amount of nutrients present in the soil layer is sufficient.
These mini ecosystems can easily adjust to temperature changes, but you might need to provide the perfect environment for them to thrive and stay healthy. Avoiding direct sunlight and heat exposure during hot summer days is recommended, as well as ensuring they�re not exposed to freezing temperatures and snow during winter. Since most of our terrariums are little rainforest recreations, we recommend keeping them in environments with temperatures between 40/85F � 5/30C, being 65/75F � 18/24C a perfect range.
Terrariums can be placed anywhere as d�cor element, substituting garden in areas with little space, as long as you avoid direct sunlight and excessive heat conditions. Consider a bright and cool room or office as the best scenario, you can always move it around but we do not recommend to do this often, since plants will adapt to the environment and sudden changes may cause plants to die suddenly. Avoid dark spaces too. Fluorescent light is also fine with the terrariums.
If you ever spot any insects in a terrarium, they�re usually harmless and it�ll be your ultimate decision keeping it or removing it. Common bugs include: caterpillar, beetles, spiders, which don�t affect the terrarium�s environment whatsoever. If you decide leaving them alone, they�ll eventually die on their own and then they can be removed with a cotton swab, twizzles or a long stick. We do not recommend using insecticides or other chemicals to get rid of bugs, there is a chance of harming or even killing the terrarium.

Given the temperature difference between the terrarium and the room where it's placed, you all notice some fog appearing on the walls of the container due to condensation. This is completely normal, and it is part of the small scale water cycle taking place inside the mini ecosystem. If instead, you see water drops running down the walls of the container, chances are there's too much moisture inside. Proceed to take off the lid for a couple hours to let some of the moisture to evaporate and put it back on.

There�s no two alike. Every piece that we make is unique since it�s all based on ideas that pop up when we start making them. Plant position, plant selection, stone colors, scenery and landscape recreation may vary. However, we will stick to the pattern of the chosen model so you won�t get something completely different to what you saw on our portfolio or social media.

Closed ecosystem terrariums, often enclosed with cork, create a self-sustaining environment. Partially closed terrariums, like geometrical ones, require occasional ventilation and may need more care to maintain the balance of moisture and air.
Terrariums are designed to be sealed, minimizing the likelihood of attracting bugs. Proper maintenance and cleanliness can further prevent any bug issues.
While it's possible to add small, harmless insects like springtails to assist with decomposition and nutrient recycling, it's essential to research the specific needs of these insects and ensure they won't harm your plants.
