A closed terrarium is essentially a miniature landscape with its own rain cycle. Compared to open terrariums and dish gardens, your plant and container choices are limited. However, unlike other setups, closed terrariums require minimal effort to maintain once they’ve been planted. Closed terrariums don’t need to water at all, it should be moist all the time, the only time you need to water your terrarium is when you notice that your closed terrarium is not being moist. Also, remember to open the lid once in a while (every 2 weeks or so) to let some fresh air inside the terrarium.
