Open or closed Terrarium? Do terrariums need to be enclosed?
Terrariums are generally known as a sealed or contained glass environment in which plants are kept. However, some might be wondering if all terrariums need to be enclosed.
Enclosed terrariums are effective as the enclosed environment allows for water to evaporate into the air, then condense on the walls of the terrarium, falling back into the soil or growing medium. Enclosed terrariums effectively create their own mini ecosystem, and don’t require watering very often at all.
But can you create and maintain a Terrarium that is open with no lid or closure?
The answer is yes, it just doesn’t work as effectively as traditional enclosed terrariums when it comes to sustaining itself. Open terrariums let evaporated water escape, so plants are at risk of drying out. This is especially so as most terrariums don’t hold much soil or growing medium, and so it doesn’t take long to dry out between watering.
Open Terrariums Can Work Well When Done Right
If you are going to create open terrariums, globe style terrarium containers work particularly well. Globe shaped Terrarium enclosures, because of their shape, are still able to create somewhat of a Terrarium effect as the water in the soil will still condense and fall on the curved Terrarium container walls.
Lots of amazing terrariums have been created without being enclosed. With open Terrarium containers, your plants are free to continue to grow by crawling their way out of a terrarium opening to create impressive miniature garden displays.
