When beginning I used the Far Red with 12/12 to get a control harvest and then added 1/2 hour at a time up to 14/10.

12/12:
The production of spontaneous seeds quit completely with the addition of the Far Red while yield remained unchanged. Yields are based on previous years harvests, this is not a side by side.

12.5/11.5:
Same as 12/12 as far as large effects, yields not obviously larger.

13/11:
Plants relaxed at the end of the day indicating their maximum DLI had been reached. The lights were raised and an extra plant fitted into the larger footprint. Individual plants maintained their yields with the longer time under reduced light. Going from five plants to six caused a 20% increase in total production.

13.5/10.5:
Occasional spontaneous seeds began showing up along with tiny sterile preseeds in the calyxes.

14/10:
The plants became as they were with 12/12 without the far red.
Viable seeds appeared in lower buds and the surface of the solvent solutions were covered with the tiny sterile seed kernels.

The bud room is now on 13/11 as the best compromise. This does away with seeds showing up in buds and allows the larger footprint and extra plant.
I use just under 250 watts of Far Red from 4 foot passive LED bars surrounding the plants high and low. Half the wattage also got results but I had to use care and turn the plants without fail to get full coverage. Overkill is so much easier and 250 watts for an hour per day costs extremely little.

I am putting the leftover Far Red floodlights up over the autoflowers and am going to leave them on all night, same as the sky does 60 degrees north where the plants come from.
Just out of curiosity.

Growmau5 last grow used additional reds, he says at the 10min mark that he couldn't see the difference.

Studies i saw all used 15 min minimum. So i am guessing that must be a sweet .

Also if your using hps it all ready has alot of far red bulb depending. So i would guess it would have little effect for the majority . also the typ of far red is vary important so i would be interested to know what far red was used . i heared from a vary reliable source that a commercial crew in the pnw has used this far red for years since the early 90s as part of a 10+ flowering step program . there smoke was always a step above the rest . i have yet in 14 years to meet the quality they used to put out so to say the least there is alot for us all to learn . i dont know about the reast of ypu out there but the more i learn the more i dont know . there is life times of knowledge out there . all input can be helpfull . just my 2 cents

I put this link into threads every now and then. It covers the basics of how Far Red affects the flowering cycle.

This link is on light itself. Towards the end is an account of the Emerson Enhancement Effect which I think is what some folks associate with Far Red.
It is not really too complicated but the link has pictures and graphs which help to clarify.
