Talk to me about a sunrise sunset. I know the usefulness of the sunset timer (if using 730nm), but what do you do for sunrise?
This is a question I've been pondering myself..
From my readings, both blue and red light are used by the plant to help regulate circadian rhythms and "wake up". Red light (660 nm) much more so.
Blue light stimulates cryptochromes and is used during phototropism in anticipation of daylight, as well as stomata opening in preparation for some full blown photosynthesizing.
I wonder what a small amount of blue light would do say 15-30 mintues before lights on? Similar to the horizon before the sun crests it. Then maybe 5-10 min of red light just before lights on as well.
Could emulating sunrise wake the plants up faster, much like emulating sunset puts them to "sleep"? Curious.
