Indoor Terrarium Singapore: Complete Guide to Building & Maintaining a Terrarium Indoors [2026]

If you’re searching for indoor terrarium singapore, you’re likely trying to figure out one thing:

How to bring nature into your home without needing a full garden or outdoor space.

Living in Singapore often means limited space. But that doesn’t mean you can’t enjoy greenery. An indoor terrarium is a practical, low-maintenance way to create a miniature ecosystem inside a glass container — whether it’s a glass jar, a fish tank, or specially designed terrarium containers.

This guide will show you:

• How to build a terrarium properly in Singapore’s climate
• Which terrarium plants thrive in a closed terrarium
• Common mistakes people make with the soil and drainage
• Practical DIY terrarium ideas you can try
• When workshops make more sense than going fully DIY

Let’s break it down step by step.

What Is an Indoor Terrarium?

An indoor terrarium is a miniature ecosystem built in a terrarium container made of glass. Terrariums are self-contained environments that replicate aspects of nature within a controlled space.

In Singapore, terrariums are especially popular because:

• Apartments limit garden space
• Air-conditioned homes create stable indoor environments
• People want greenery without daily maintenance

A terrarium is typically created in a glass container — such as a glass jar, fish tank, or purpose-built terrarium container. The container influences airflow, moisture retention, and plant choice.

There are two main types:

A Closed Terrarium

A closed terrarium is sealed or semi-sealed. Moisture cycles within the glass container, creating a humid microclimate. This works well for mosses, ferns, and tropical terrarium plants.

In a closed terrarium, condensation is normal. But you need to monitor airflow to avoid mold.

Open Terrariums

Open terrariums have an opening that allows airflow. These are better for succulents, air plants, and desert plants that dislike high humidity.

In our experience running terrarium workshops in Singapore, beginners often confuse plant compatibility. The plant choice determines whether you should use a closed terrarium or an open one.

Choosing the Right Terrarium Plants in Singapore

Selecting the right terrarium plants is critical. Not all plants that look small will survive in a terrarium.

Here are some of the most suitable plants for indoor terrarium singapore setups:

Mosses and Ferns

Mosses and ferns thrive in humid environments. A fern like the button fern works well in a closed terrarium. Mosses create lush ground cover and help regulate moisture in the soil.

Nerve Plant (Fittonia)

The nerve plant is one of the most popular terrarium plant options. It tolerates humidity and adds vibrant colour contrast.

Creeping Fig

Creeping fig works in larger terrarium containers where space allows for trailing growth.

Air Plants

Air plants are ideal for open terrariums. They don’t require soil but still need airflow and occasional misting with a spray bottle.

Succulents and Desert Plants

Succulents and desert plants must never be placed in a closed terrarium. They need airflow and dry soil conditions.

In Singapore, plant choice should always match the container and environment. If you mix incompatible plants, your terrarium may struggle within weeks.

How To Build an Indoor Terrarium (Step-by-Step)

If you are exploring terrarium DIY at home, structure matters. Most failures happen because people skip layers.

Step 1: Choose Your Terrarium Container

You can use:

• A glass jar
• A fish tank
• A wide-mouth glass container
• Specialised terrarium containers

The size of the container affects drainage and airflow. In a closed terrarium, ensure there is some opening to allow occasional ventilation.

Step 2: Create the Base Layers

Inside the terrarium container, layering is crucial.

1. Drainage stones (bottom layer)
2. Activated charcoal
3. Mesh barrier (optional but recommended)
4. The soil

The soil must be well-draining and suitable for terrarium plants. Regular garden soil is not ideal.

Most indoor terrarium singapore setups fail because people overwater without proper drainage.

Step 3: Add the Plants

Gently remove the plants and loosen the roots. Place them in the soil and ensure spacing.

Avoid overcrowding. In a small terrarium, less is more.

Position taller plants at the back and mosses or low-growing plants at the front.

Step 4: Decorate Thoughtfully

You can add:

• Sea glass
• Small stones
• Natural wood
• Minimal figurines

Decorative elements should complement the plants, not overpower them. The terrarium is about balance.

Step 5: Water Carefully

Use a spray bottle. In a closed terrarium, you only need a few sprays. Overwatering is the main problem.

If condensation builds heavily on the glass, open the container briefly.

Maintenance Tips for Your Terrarium

Low maintenance does not mean no maintenance.

Here’s what you need to monitor:

• Moisture levels in the soil
• Mold growth
• Overgrown plants
• Condensation in a closed terrarium

Trim the plants when they touch the glass. If you see mold, increase airflow.

Terrariums are small ecosystems. Small adjustments make a big difference.

DIY Terrarium Ideas You Can Try

If you enjoy hands-on projects, here are a few terrarium DIY ideas:

• A mini forest theme using mosses and ferns
• A desert theme using succulents and desert plants
• A sea glass decorative terrarium
• A large fish tank turned into a statement indoor garden

DIY terrarium ideas are great for personal use. However, if you are planning for a group or corporate setting, structure becomes important.

When Should You Consider Terrarium Workshops?

If you are organising for a corporate team, school group, or mixed-age participants including a kid and adult audience, workshops are often more effective than fully DIY attempts.

At Terrarium Singapore, we specialise in structured workshops designed for different group sizes and objectives.

Pax & Pricing: For teams of 5 pax and above. Price starts from $30 per pax.

In our experience running terrarium singapore workshops:

• People engage better when materials are pre-prepared
• Clear pacing avoids confusion
• Facilitators assist quietly without overwhelming participants
• Aftercare guidance improves long-term plant survival

Unlike random DIY setups, professionally run workshops ensure plant compatibility, proper layering, and hygiene standards.
