I usually post this every year to notify people who buy annuals like
Impatiens or even Petunia's to carefully look at the plants and the
size of the foliage. If it looks smaller than it should look, this is
not just because it is a young plant. It means the production
schedule in the greenhouse made it necessary to use growth regulators
or inhibitors. This is a class of chemicals which can, and often does
stunt the growth of the plant indefinitely. Many annuals will come
out of it, but if the plant is too far along in the six pack or 4"
pot, and if these inhibitors are used the plant is stunted in a more
mature point in that plants life...mature for shelf at market, that
is.
So, be aware and don't buy this type of plant even if it had a million
buds. It will have those buds as a response to dying or stress to
reproduce.

Wouldn't switching photoperiod have the same effects?

Not as cheaply.

Depends on the plant, and whether you're using
natural or artificial light.

Okay, so I guess my instance which was very specific to giant
greenhouse operations didn't seem to enter your mind, I'll say it
again with the addition of natural light situation, huge operations
under glass, shipping out tractor trailers of flats day and night,
with hundreds of employees and a head house operation of three to six
belts with 20-30 operators planting plugs on two shifts. It is
cheaper to use growth inhibitors.
The only time artificial light is used are for very limited crops
which are hugely smaller than that of annual flats production of
impatiens and all the ordinary plants which people fawn all over.
