Perhaps, perhaps not. No one really knows.

730nm for 15min after light out should speed up flowering because the plants switch faster to night metabolism. Some guys run 13/11 light for flower and got extra harvest because of the extra energy. Others run normal 12/12 and got some speed up with flowering. There are some informative threads out when u search 730 or far red.

Apogee instruments has a YouTube channel through which they discuss this and other topics (required ppfd, effect of spectrum, Emerson effect etc). Worth a look.

My Spider Farmer 4000 LEDS has some IR 760nm diodes.

What Spider Farmer says:

Speeds up the Phytochrome conversion, allows the plant to produce a greater yield.
