Terrarium Tools & Supplies: What You Actually Need (and Why Most Stuff Is Useless)

Terrariums look magical when they’re done right.
They also look like a sad science experiment when they’re not.

Most people don’t fail at terrariums because they’re “bad with plants.”
They fail because they use the wrong materials or copy incomplete tutorials.

This guide strips things down to what truly matters — the tools and supplies that decide whether your terrarium survives for months or for decades.

 

Why the Right Terrarium Tools Matter (More Than Talent)

A terrarium is a closed ecosystem.
You don’t get infinite second chances.

Wrong soil? Mold and rot.
Tap water? Mineral buildup and dying moss.
Messy planting? Damaged roots from day one.

The right tools don’t make you creative.
They make you precise, clean, and consistent — which is what terrariums actually need.

 

The Essential Terrarium Tools (Skip These and You’ll Regret It)

1. Long Tweezers – Non-Negotiable

If you buy only one tool, this is it.

Long terrarium tweezers allow you to:

  • Place plants without damaging roots

  • Adjust moss and stones precisely

  • Work deep inside glass containers without destroying your layout

Using fingers leads to crushed plants and compacted soil.
That damage doesn’t “heal” later.

2. Small Scoop – Clean Layers, Clean Glass

Terrariums are built in layers.
Messy layers = messy ecosystem.

A small scoop helps you:

  • Place drainage and soil exactly where needed

  • Avoid soil sticking to the glass

  • Control depth without overfilling

This is especially important in open and showcase terrariums where everything is visible.

3. Distilled Water – Yes, It Matters

This is where most people quietly kill their terrariums.

Tap water contains:

  • Minerals

  • Chlorine

  • Limescale

In a closed terrarium, these accumulate over time and damage plants and moss.

Distilled water:

  • Leaves no residue

  • Keeps glass clean

  • Protects sensitive plants long-term

This isn’t optional if you want longevity.

4. Yellow Sticky Trap – Small Tool, Big Save

Sometimes fruit flies hatch from organic matter inside a terrarium.
It happens — even in well-built systems.

A yellow sticky trap:

  • Attracts and captures fruit flies

  • Stops infestations early

  • Requires no chemicals

In terrariums, it doesn’t need to go into the soil.
You simply place it between the glass and the lid, where it stays discreet but effective.

 Bonus Tip: They're also perfect for your houseplants, they help trap pests like spidermites, helping both treat and prevent your plants from getting eaten by pests.

Ignore flies and they multiply fast.

Terrarium Supplies That Actually Keep Plants Alive

5. Drainage Layer (Expanded Clay or Sand)

Roots should never sit in water.

The drainage layer:

  • Stores excess moisture

  • Prevents root rot

  • Stabilizes the ecosystem long-term

Use:

  • Expanded clay for most terrariums

  • Sand for very small or minimal designs

Thickness guideline:

  • Small terrarium: ~2 cm

  • Large terrarium: 3–4 cm

👉 Expanded clay

6. Activated Charcoal – The Silent Protector

Activated charcoal isn’t decoration. It’s insurance.

In a terrarium, it helps to:

  • Absorb impurities and odors over time

  • Reduce the “swampy” smell that can happen in closed systems

  • Support a cleaner environment when organic matter breaks down

It won’t fix bad watering or bad soil — but it reduces risk and makes the ecosystem more stable.

7. Proper Terrarium Soil – Not “Any Soil” (This Is the Most Important Part)

This is where terrariums live or die.

Regular potting soil is:

  • Too rich

  • Too wet

  • Designed for open airflow (which terrariums don’t have)

Our Terrarium Soil is based on the ABG mixture — widely considered the best soil mix for terrariums and bioactive ecosystems. It's from a family-recipe that consists of up to 8 different ingredients

Why ABG-based soil works:

  • Excellent drainage

  • Long-term structure (doesn’t collapse)

  • Supports roots without suffocating them

  • Resistant to mold when used correctly

This type of soil is used in professional terrariums that are designed to outlive their creators.

Trying to mix soil yourself is where most people go wrong.
One wrong ratio and the entire system slowly fails.

If you want your terrarium to live long, don’t gamble here.

Optional (But Worth It)

Moss

Not just decoration:

  • Regulates humidity

  • Protects soil surface

  • Makes the ecosystem stable and finished

👉 Live Moss

Decorative Stones or Wood

Purely visual — but visuals matter.
A terrarium should look intentional, not accidental.

 

What You Don’t Need (Save Your Money)

❌ Fertilizers
❌ Grow lights for indoor terrariums
❌ pH meters
❌ Random “starter kits” with cheap soil

Terrariums thrive on balance, not gadgets.
