Frame a layered miniature garden with the ProRep Mini Terrarium 30x21x30cm. Its combination of a 30cm-wide front, a shallower 21cm depth and 30cm overall height creates an inviting space for a planted backdrop and low foreground. It is a good shape to consider when you want more visual width than a narrow tower without choosing a deep, square enclosure.

Compose a scene from front to back

Use the rear of the terrarium for one restrained upright feature, such as a slender piece of cork or a compact fern. A low planted area in front gives a sense of depth without needing bulky decoration. Keeping one side more open also lets the shape of each leaf stand out against the glass.

The 21cm front-to-back measurement makes it especially important to account for any background material. A thick panel or large piece of wood can take up a substantial part of the planting area. Try the arrangement before adding growing medium, and check that there is still space for roots and a comfortable route for maintenance tools.

Combine a few complementary plants

A small tropical fern could provide the upright texture, with a compact Fittonia creating a lower patch of veined foliage. Use only forms whose eventual dimensions fit the enclosure, and choose plants with compatible growing needs. Keeping the palette limited can make the finished display feel more coherent than a mixture of unrelated specimens.

Suitable terrarium moss may be used sparingly around an exposed section of décor. Leave enough clear ground to inspect the planting rather than covering every surface immediately. The foliage will change as it settles in, so a little empty space at the start allows the arrangement to develop without becoming difficult to manage.

Accessible planting behind clear glass

Tempered glass panels provide views of the layered scene. Access is through the sliding mesh lid at the top, rather than a door in the front. Keep tall leaves, bark and any light fitting clear of the opening so that regular care does not become awkward. The raised feet leave an air gap below the base.

The mesh top permits ventilation, but it also lets moisture escape. This is not an airtight terrarium that can be left to recycle its water indefinitely. Humidity-loving plants need conditions checked after planting, particularly when indoor heating makes the surrounding air drier.

Plan the practical details first

Select a clean growing medium that supports the chosen root systems without remaining waterlogged. The final substrate level reduces the usable height for foliage. Water cautiously and keep access to any area where excess water might collect; a layer beneath the compost does not provide an outlet from the enclosure.

Provide suitable indirect light and check that the upper planting does not shade everything below. A separate plant light may be useful away from a bright window. Avoid strong direct sunshine and keep the terrarium on a stable surface with space to operate the lid.

Plants, growing materials and equipment should be chosen separately. The design also has animal-housing uses, but compatibility with any species must be assessed independently of this suggested planted layout.
