Worldwide Orchids :

The ideal temperatures for Phalaenopsis are 85' F. during the day and 64' F. at night.

Phalaenopsis require air movement, especially when temperatures exceed 85' F. If the environment does not provide for air circulation, a small fan may be necessary.

Phalaenopsis do NOT like temperatures above 90' F.

The best humidity levels for Phalaenopsis range from a low of 40% to a high of 80%.  If the humidity is higher than 80%, increase air movement.

Cooler temperatures at night will help initiate flower spikes.  Do not let the plants go below 50' F. or damage could result.
