Create miniature self-sustaining ecosystems within glass containers.
Reviewed May 18, 2026
First terrarium
Build a closed terrarium
A glass jar or bottle with a lid, drainage layer, substrate, and small tropical plants (ferns, moss, fittonia). Closed terrariums are self-sustaining mini-ecosystems that water themselves.
Learn the drainage layer
Pebbles or LECA (lightweight expanded clay aggregate) at the bottom prevents roots sitting in waterlogged soil. Without drainage, all terrariums rot.
Choose the right plants
Slow-growing, humidity-loving plants (ferns, mosses, fittonia, peperomia) suit closed terrariums. Fast-growing plants outpace their container in months.
Craft and sharing
Build a terrarium as a commissioned gift
A commissioned or gifted terrarium requires understanding the recipient's light conditions, care preferences, and aesthetic. Meeting a brief is different from building for yourself.
Sell terrariums at a craft fair or online
Terrariums sell well at markets and on Etsy. Pricing requires accounting for container, plants, substrate, hardscape, and time. Build-to-order is more efficient than speculative stock.
