If your nights are cool, I would not grow your Phalaenopsis outdoors. I would recommend that you get a max/min thermometer, and find out for yourself what your conditions are. Most Phalaenopsis will take 60F (16C) at night regularly, and occasionally down to 55F (13C). Humidity isn't really a problem. My Phals are experiencing 20% humidity right now, and the plants are fine, but some of the more tender flowers are having a shortened life. I will be raising the humidity soon with a tray of gravel and water which the Phals will sit on, but with water NOT touching the pot bottoms, as that would cause continuous wetness and rotted roots. High temps are not much problem for Phals. The other thing I will be doing is getting a special heating pad that goes under the tray of water the a thermostatic control to keep the water at a set temperature to add heat to the area (and promote evaporation too) when the weather is such that we stop using the house heater, spring and fall, and I need a little more heat for the Phals. The Phals are currently under fluorescent lights in the bath room that is a very small room with its own heater vent, resulting in it being a very warm room in winter.

And, Phals can take repotting anytime.
