This bottle is a nice display unit.
I have seen some nice terrariums with Haworthias in them.
Haworthias like to be dry so you do not have to water them often.
They have shallow roots so they do not need deep soil.
They are slow growers and make wonderful indoor plants.
That large round hole in the side looks like it can be used to replant your new garden.
Does your hand fit through the opening?
You can use tongs to move the plants around.
