Let’s Talk About Closed terrariums!

A closed terrarium is a miniature garden enclosed in a sealed container. It is a low-maintenance way to bring the beauty of nature indoors, and it can be a great addition to any home or

To create a closed terrarium, you will need a clear glass or plastic container, substrate (soil), rocks or pebbles, charcoal, and a variety of plants. It’s important to choose plants that like the high humidity a closed terrarium provides. Here are some examples; Fittonia, Ficus pumila, & most Peperomia species.

The first layer of your closed terrarium should be a few centimetres of gravel or pebbles. This layer helps with drainage and prevents the roots from sitting in water. Next, add a layer of charcoal, which helps keep the terrarium fresh by absorbing toxins and odors.

After the charcoal, add a layer of substrate. Once the soil is in place, it's time to plant your terrarium. Choose plants that are small and have similar environmental requirements.

Once you have planted your terrarium, water it lightly, and then seal the container. The seal will create a miniature greenhouse effect, where water is recycled and the plants create their own oxygen. The only time you will need to open the container is if there is too much condensation or if the plants are growing too fast.

Closed terrariums are a great way to add greenery to your home or office without having to worry about watering or fertilizing plants constantly. They are also a fun and educational project for kids, as they can learn about the water cycle and plant growth in a hands-on way. With a little bit of care, your closed terrarium can thrive for years to come.
