1. Environment and Climate Control

• Light: Provide bright, indirect light. Use a green shade net (around 75% shade) or place them near an east-facing window indoors to avoid harsh midday sun which can scorch the leaves.
• Temperature: Maintain a temperature range of 18°C to 30°C (65°F to 86°F). Protect plants from extreme heat above 32°C (90°F) and cold drafts.
• Humidity: Aim for high humidity, between 50% and 70%. Use a humidity tray (a tray with pebbles and water) or mist the plants frequently, especially in dry conditions.
• Air Circulation: Ensure good airflow to prevent fungal issues, which are common in high humidity environments. 

• Pot: Use small, well-draining pots, as these orchids prefer slightly restricted roots. Perforated plastic or clay pots are ideal.
• Medium: Use a specialized, well-draining orchid mix (not regular soil) such as a mix of fir bark, perlite, charcoal pieces, and/or coconut husk/fiber. 

• Watering: Water thoroughly in the morning, but allow the potting medium to dry out slightly between waterings. Overwatering can lead to root rot.
• Water Quality: Use rainwater or filtered water if tap water has high levels of fluoride or chlorine.
• Fertilizing: During the active growing season (spring and summer), feed with a balanced orchid fertilizer (e.g., 20-20-20 NPK) diluted to half strength every 2 to 4 weeks.
