Phalaenopsis Orchid Care:  Temperature & Ventilation

 

* There should be  good air movement to keep the leaves cool. Warmer weather often means higher temperatures so increase air movement as well.

*In cool humid damp conditions(winter) its very important to keep air moving to avoid fungal or bacterial infections which can decimate plants in a matter of a few days.


 

TEMPERATURE AND VENTILATION 
Phalaenopsis orchids are considered warm growing orchids. They need night-time temperature lows of about 65F (18C) and tolerate day-time temperature highs of about 85F (29C). A few degrees divergence from these temperatures is tolerated.

Orchids need at least a 10 degree difference between night-time lows and day-time highs to thrive. Why? Because orchids synthesize their food through photosynthesis, during the day. If night temperatures are too high, they end up burning up this food--they need lower temperatures at night in to save their food, which they can then use to flower. This night time temperature drop is required by many moth orchids if they are to bloom. Don't worry, there are some easy tricks to give them the nighttime temperatures that they need to flower.

A drop in night temperatures (to about 55-60) for a month, especially during the fall or spring will induce flowering in season. Wireless Min/Max Thermometer  can help you keep track of changes in temperature.

Make sure that there is always adequate ventilation and air circulation, particularly in the winter, or during very humid conditions, in order to avoid fungal and bacterial disease. However, do not subject plants to blasts of cold or hot air. An oscillating fan that moves air constantly at low speed is extremely beneficial.
