After I saw far red discussed in a grow thread on an auto, I just happened across this last night and thought I'd share.
Some takeaways from the clip:
Far red passes through the leaf better than colours lower in the spectrum, reaching lower leaves but also triggers the plant to grow taller which can result in gangly looking plants.
There's pros and cons, far red is better suited to some plants than others.
Causes cell expansion, larger leaves hence good for lettuce spinach, however plants can stretch too much when far red > 5%, reducing the density of your grow.
Can be used to control flowering of long day plants, not useful for flowering of short day plants (Cannabis)
The sun does produce far red but it's counterbalanced by the blues.
