Winter Care for Phalaenopsis in Cold Climates: Bathroom vs. Window

In southwestern Connecticut, harsh winters challenge Phalaenopsis. A bathroom offers humidity but lacks light; an east window with supplemental lighting is superior.

Optimal Winter Setup

• Location: East-facing window, set back from cold glass.
• Light: 12–13 hours supplemental plant light if natural light low.
• Humidity: Pebble tray with water (pot above water line).
• Temperature: 65–85°F; avoid drafts.
• Air movement: Gentle fan for uniform air mixing.

Bathroom Limitations

High humidity is beneficial but insufficient without adequate light and temperature stability. Bathrooms often have fluctuating temps and low light.

Key Takeaways

• East window + grow light > bathroom for winter.
• Pebble tray maintains humidity without soggy roots.
• Keep 65–85°F; gentle air circulation prevents fungal issues.

Create a complete microclimate: light, humidity, temp, and airflow.
