OUR KNOWLEDGE HUB > START A MECHA & MOSS TERRARIUM
Mecha & Moss Terrarium
Part of Green Chapter’s Knowledge Hub
Not every story needs to be told with words.
Some are built — piece by piece — through steel, soil, and time.
The Mecha & Moss Terrarium is a unique experience created by Green Chapter, where the precision of Gunpla craftsmanship meets the calm, living world of terrarium design. Whether you’re recreating an iconic battle or imagining your own alternate timeline, this is where your story takes physical form — inside a living ecosystem.
You’ll learn how to weather and transform a Model Kit, then place it within a carefully built natural landscape — turning a static model into a moment frozen in time.
If you're new to terrariums, you may also explore our Enclosed Terrarium Mini Hub to better understand how these ecosystems work.
Start Here — Build Your Scene Step by Step
Follow these 8 guided articles to go from idea → finished display.
Each step is designed to help you think, build, and refine your scene with intention — even if you’ve never touched Gunpla or terrariums before.
What is a Mecha & Moss Terrarium
Where Machines Meet Nature
Learn how a RX-78-2 becomes part of a living ecosystem, and why this guide builds on your Closed Terrarium fundamentals.
STEP 1: Choose Your Story
What-if imagination or anime-accurate recreation
Decide if you're creating a fallen Gundam reclaimed by nature, or recreating a battle from the Gundam universe.
STEP 2: Plan Your Scene
Translate your idea into terrain and scale
Test how your Model Kit fits within your hardscape before committing to the build.
STEP 3: Choose Your Container
Match your story and scale to the right space
Use DEW CUP for compact 1/144 HG scenes, or SKYBOX for larger builds, 1/100 models, and dynamic compositions.
STEP 4: Build the Landscape
Create terrain that feels grounded and believable
Shape cliffs, ruins, or damaged environments using rock and wood to anchor your scene.
STEP 5: Weather Your Mecha
Give it a history of battle and time
Apply damage and weathering techniques to transform your model into a believable survivor.
STEP 6: Plant The World
Bring your scene to life with moss and growth
Integrate plants, terrain, and Gunpla into a single living environment — whether placed early or at the final stage.
STEP 7: Maintain & Protect Your Build
Preserve Both Nature and Machine
A living terrarium changes over time — and your model must withstand it.
Learn how to manage humidity, protect your Gunpla, and maintain your ecosystem for long-term display.
Bring It Together
By now, you’ve gone from an idea to a complete Mecha & Moss terrarium.
This is more than placing a model in a container — it’s building a living scene.
You’ve learned to think in scenes, shape terrain with purpose, and bring your Gunpla to life through weathering. Plants and structure are no longer separate — they work together as one environment.
When everything is balanced, the result feels natural, complete, and alive.
What You’ll Understand
You can now design your own scene with intention — from choosing the right container to building terrain, applying weathering, and integrating plants into a cohesive environment.
More importantly, you understand that this isn’t decoration.
It’s world-building.

If you want to go further, explore other systems in the Knowledge Hub — from closed terrariums to larger habitat setups and planted tanks.
Each one builds on the same idea: creating stable, living environments.
Experience It Hands-On
Reading helps, but building makes it real.
In our Mecha & Moss workshop, you’ll be guided step by step — from planning your scene to building, weathering, and completing your own terrarium.
