What is the importance of far red light?

@shag

Run full spectrum for 14 hours then just run the far red light for 15min just before lights off, then 10 hours of total darkness.

So the red light turns off 15 min. after the full spectrum turns off …you will have 14 hours of full spectrum light then 15 min. of Far red light, then total darkness for 10 hours, really 9 hrs 45 min.

@SaintAliasKnife
I had this part worded wrong.
This is the only part I made changes to.
