Terrariums are typically glass containers that can be sealed or left open, housing plants, moss and greenery. Closed terrariums create a unique environment for plant growth, as the glass walls allow plenty of light and heat to enter which in-turn creates a small-scale water cycle essential to plant growth. Not only that, but the oxygen that is created is great for the air in your home, which makes the simple beauty they provide just icing on the cake. Closed terrariums are perfect for mosses, ferns, orchids and air plants – all found in more tropical climates, mimicked in the enclosed terrarium environment. Open terrariums are better for drier plants like succulents or plants that need a lot of direct sunlight, but not a lot of heat.
To make your own terrarium, all you need are a few key items, like a glass enclosure of any kind, potting soil, sheet moss and/or terrarium plants and activated charcoal pieces. Once you’ve lined the bottom with 1 to 2 inches of charcoal, combine the rest with the potting soil and begin to build your terrarium, placing the plants on top with proper space between for more soil.
