What Your Terrarium Really Needs

Gentle guidance on natural substrates, drainage, and coverings — no complexity required.

What are the essential layers in a closed terrarium?

From bottom to top:

Drainage layer: 2.5–5 cm — natural pebbles, river stones, gravel, or LECA/clay balls. Catches excess water to protect roots.
Activated charcoal (thin layer): 0.5–1 cm — filters water, reduces odors, prevents mold. A little goes a long way.
Barrier (optional): Sheet of sphagnum moss or landscape fabric to stop soil mixing downward.
Substrate/soil: 5–10 cm, depending on plant roots — light, aerated mix (peat-free potting soil + perlite/coco coir/orchid bark). Avoid dense garden soil.
Top layer: Live sheet moss, preserved moss, or natural stones/bark — thin covering for humidity and aesthetics.

This setup creates a self-sustaining cycle where water condenses and recirculates naturally.

How much of each material do I need?

Rough guide for a medium jar 1–2 liter:

Drainage: 2.5–5 cm
Charcoal: 0.5–1 cm
Soil: 5–10 cm — enough for roots but leave headspace for plants and air.

Scale proportionally for larger/smaller containers — always prioritize observation over exactness.

What’s the best drainage material?

Natural river pebbles or polished stones (like our MossBoss drainage pebbles) in small-medium size (0.6–1.3 cm) for good airflow and gaps. Alternatives: aquarium gravel, lava rock, or LECA. Avoid sharp materials that could scratch glass or roots.

What soil/substrate should I use?

Light and draining:

ABG mix (orchid bark, tree fern fiber, sphagnum, charcoal) for bioactive.
Simple blend: peat-free potting mix + 20–30% perlite/coco coir + some charcoal.
No added fertilizers — low-nutrient is best for balance.

Can I use decorative items like colored stones, glass beads, or figurines?

Yes, but keep it minimal and natural: polished river stones, slate, bark, or driftwood. Avoid painted, glazed, or metallic items — they risk leaching in humidity. Rule: if it doesn't support the ecosystem, skip it.

Where can I source good materials in Bulgaria?

We stock natural drainage pebbles, activated charcoal, live/preserved moss, substrates, and tools at www.mossboss.bg — chosen for calm, long-term terrariums.

If you're assembling one now, share your jar size (in cm or inches) or plant types — we'll suggest precise layer depths and materials in our voice. Care for something real.
