🍃 Restrepia trichoglossa Terrarium Care Sheet (Vented Setup)
Overview:
Restrepia trichoglossa is a miniature, epiphytic orchid from the cloud forests of Central and South America. Known for its delicate, exotic flowers and fine root system, it thrives in a cool to intermediate, humid environment—making it ideal for a vented terrarium with good airflow and stable moisture.📏 Size & Growth Habit
Type: Miniature epiphytic orchid (Pleurothallidinae)
Mature Size: ~7–10 cm tall
Growth Habit: Compact, with thick leathery leaves and fine, hair-like roots; blooms from base of leaves
💡 Light Requirements
Light Level: Low to moderate
Lux Range: 6,000–12,000 lux (equivalent to 600–1,100 foot-candles)
Best Placement: Shaded corner of a terrarium, or near a north- or east-facing window; ideal under low-intensity LED grow lights
Caution: Direct sunlight will scorch the leaves
🌡 Temperature & Humidity
Daytime Temps: 18–24°C
Nighttime Temps: 12–16°C
Humidity: 75–95%
Airflow: Gentle but consistent—ventilation is essential to prevent bacterial rot and fungal issues
💧 Watering & Moisture
Watering Frequency: 3–4 times/week, or daily in hot/dry weather
Water Type: Rainwater, distilled, or RO water—sensitive roots!
Drying Cycle: Keep evenly moist—do not let roots dry completely
Misting: Light misting in the morning; avoid water pooling on leaves
🌱 Mounting & Medium
Preferred: Mounted on cork or tree fern with a pad of sphagnum moss
Alternative: Small net pot with fine-grade orchid bark and sphagnum mix
Terrarium Note: Raise mount or pot above any drainage layer; maintain high ambient humidity but allow surface drying
🌬 Airflow
Non-negotiable: Restrepias are extremely sensitive to stagnant air
Use passive vents or small fans
Open terrarium periodically to refresh air
Avoid sealing it completely for more than a few hours
🌸 Flowering & Rest
Bloom Habit: Can flower repeatedly throughout the year
Flowers: Small, alien-like blooms with long tails; often yellow, purple, or spotted
Rest Period: None required—can grow and bloom year-round if conditions remain stable
🌿 Fertilizer
Type: Very dilute orchid fertilizer (e.g., 20-20-20 or MSU type)
Frequency: Every 2–3 weeks during active growth
Strength: 1/8 to 1/4 strength—this species is sensitive to salts
⚠️ Common Issues
| Issue | Cause | Solution |
|---|---|---|
| Leaf spotting or drop | Poor airflow or water on leaves | Increase ventilation; water in morning |
| Shriveling leaves | Underwatering or root damage | Rehydrate gradually, inspect roots |
| Flower bud blast | Dry air or temp swings | Stabilize humidity and temperature |
✅ Terrarium Tips
Best suited to cool or intermediate setups with air movement
Avoid wetting the crown repeatedly—spray lightly at base
Excellent choice for bioactive or mossy terrariums with consistent moisture
Pair with miniature ferns, mosses, or other Pleurothallids for aesthetic harmony
