Growing Phalaenopsis Under Artificial Lights

Light Timer Strategy

Set a 24-hour timer to run lights 2 hours longer than natural daylength (on 1 hour before dawn, off 1 hour after dusk). This creates seasonal variation automatically.

Light Intensity & Placement

• Compact fluorescent bulbs (75W warm + 100W daylight) work for 2-3 plants in 1x3 ft area.
• Place plants as close as possible (within 6 inches) since bulbs lack reflectors.
• Estimated 500-1000 foot-candles at that distance.

Fan Usage

• 24/7 if temps regularly exceed 80°F (cooling).
• Morning only if cooler (promotes leaf drying after watering).
• Timer-synced with lights (simple automation).

Flower Spike Management

Cut brown spikes at base. For green spikes, cut above 2nd node—may branch and rebloom, though dieback is natural.
