Closed Bell Terrarium - Anoectochilus species (Jewel orchid)
Anoectochilus species, commonly known as jewel orchids, are prized for their velvety leaves traced with intricate, metallic veining rather than for their flowers. In nature, they grow along shaded tropical forest floors where humidity is high, light is soft, and conditions remain consistently moist, making them exceptionally well suited to a closed bell terrarium.
The enclosed glass environment provides the steady humidity and protection jewel orchids require, while preventing the rapid drying and temperature fluctuations that often cause decline in open setups. Because they prefer indirect light and stable indoor temperatures, this terrarium works particularly well in office environments, studios, and calm interior spaces.
A slow-growing, visually striking terrarium plant that rewards gentle care and consistency—perfect for shaded desks, shelves, and contemplative indoor spaces
Light
-
Low to medium indirect light (approx. 500–1,200 lux)
-
Bright shade or filtered indoor light
-
No direct sun
Too much light can dull leaf colour and damage the delicate foliage, while softer light preserves the plant’s rich veining and texture.
-
Temperature
-
Ideal range: 18–24 °C
-
Minimum: ~15 °C
-
Prefers stable temperatures
-
No night cooling required
Unlike cool-growing orchids, Anoectochilus does not benefit from temperature drops and may suffer if exposed to cold drafts or prolonged cool conditions.
-
Watering
Due to the compact size of this terrarium, only minimal water is required. Add water sparingly and only if condensation is absent for several days.
Condensation guidance
Light condensation on the glass is normal. Heavy, persistent condensation indicates excess moisture and can be resolved by briefly opening the terrarium.
Heat warning
Avoid placing near windows with direct sun, heaters, or electronic equipment, as small glass terrariums can overheat quickly.
Air refresh
Briefly opening the terrarium every few weeks helps refresh the air and maintain balance.
