Far Red Confusion

Guys I am a little dyslexically challenged which make doing lots of reading real difficult for me. Can someone give a simple answer to the following question please. I've been given a couple of far red booster strips to add to my cob set up but when should i run them reds strips for flowering isit just at the end of the 12 hour cycle or all through the twelve hours and should it happen just early in the flower stage ?

Most newer LED grow lights come Full spectrum now and have blue, white and red and can compliment your plants from seedling to harvest. I've never dived deep into it but from my understanding reds are best utilized by your plants during the flowering stage. I would say use them in flower?

Dr Bruce Bugbee explained it pretty well in his video on "extended Par". Far Red benefits plants at all stages. Far red alone does nothing, but works well in conjunction with "Par" you can run them the entire 12/12 cycle.

I've found that they stretch too much in veg. I use em 12/12 after they're done stretching. Really helps flower production.
