Bringing in the Orchids (question)
 

Electrician is finishing up installing a new metal halide light in
anticipation of bringing my orchids in from outdoors. Then it dawned on
me -- the orchids (catt, phal, vanda & dends) have been summered outdoors
here in western PA so have been experiencing shorter days, longer nights and
cooler temps.
Do I need to bring them back into the bright light and warmer temps
gradually? Your input will be most appreciated. Thanks
