Brassidium (Brsdm.) Golden Gamine Care: Temperature, Light, and Winter Management

Your Brassidium (Brassia × Oncidium × Miltonia × Odontoglossum hybrid) "Golden Gamine 'White Night'" is an intermediate grower needing specific winter care in cooling climates.

Temperature Requirements

• Range: 45-85°F (7-29°C)
• Winter: Move back from cold windows; maintain >50°F nights
• Adjustment: Distance from glass = temperature control

Light Management

• West window: Good, but monitor intensity
• Shadow test: Finger between leaf and window should cast distinct shadow
• Winter supplement: Clip-on LED grow light on 12-hour timer
• Cloudy climates: Artificial light essential November-March

Water and Media

• Open, well-draining mix (bark, perlite, charcoal)
• Water when media barely moist
• Morning watering only

Winter Checklist

1. Move 6-12 inches back from window glass
2. Add supplemental light on timer
3. Reduce watering frequency (slower drying)
4. Monitor for spider mites (dry indoor air)
5. Maintain humidity 50%+ (pebble tray/humidifier)

Brassidiums reward good culture with spectacular, spidery blooms. Your attention to temperature and light will pay off at flowering.
