Behind the Glass: How We Build a Terrarium in Seven Stages

A terrarium is a small system, and the order you build it in decides whether it settles or struggles. We follow the same seven stages for every made-to-order build, so each one starts from a checked foundation.

1. Sourcing

We choose the glass, plants, substrate and any decor. Plants are inspected for pests, rot and root health before they are accepted. Anything that does not meet our standard is rejected here, not later.

2. Enclosure prep

The glass is washed, dried and checked for chips, especially around the rim where the lid seals. We confirm the size against the planned layout. Fragile glass is handled one piece at a time.

3. Layering

Drainage material goes in first, then a barrier layer, then activated charcoal and finally the substrate. Each layer is levelled before the next is added. This is the stage after which a build can no longer be cancelled, because the materials are committed to the enclosure.

4. Planting

Plants are removed from their pots, root balls are loosened gently and each plant is set at the right depth. We leave room for growth and avoid burying stems. Plants that need more light or airflow are placed where they will receive it.

5. Settling

The build rests after planting, with a light watering to settle the substrate around the roots. We watch for drooping leaves and fog that does not clear. Adjustments are made here, before the lid is sealed for the long term.

6. Quality check

A second person checks the build against a written list. We look at moisture, plant health, layer stability, glass clarity and lid fit. Any build that does not pass goes back to the right stage.

7. Packing

Live goods are packed for ventilation, with padding and temperature support where needed. Glass is wrapped and boxed separately so it cannot shift in transit. The parcel is labelled as live and fragile before it is handed over for dispatch.

Dispatch follows packing on Monday, Tuesday or Wednesday. Our shipping policy explains how weather holds work and what to do if something arrives damaged. We would rather take longer than skip a step.
