Default Does 523nm green wake up plants during dark cycles?

Waiting for lights on to do work is getting to be difficult.
They make clear bulb LEDs with 523nm green in them.
Iíve read 523nm isnít absorbed by leaves or interrupts dark cycles.
Has anyone worked on garden during dark cycles with green light and had any problems?

I just fuct up a grow with green lights. Not sure of the actual color designation. I have used old green "party bulbs" with no issues.

This grow, I sent every plant back to square one.

Just be sure and be careful.

Thereís green painted bulbs and thereís now clear lense with green led that Iím trying out.
I contacted the company and they said they had 523nm LEDs in them but I bought 2 and they are different shades of green.
I at first didnít see difference because I only used one bulb but after using the second for a bit more light to work in,they donít put out the same green.
Cheap party bulbs may not have any QC.
I donít see any negative effects but I use them only for 10-30 seconds.

Iím going to make my own by using Cree xpe 2 LEDs.

One thing I noticed is looking at green makes me see red afterwards.

This is interesting.
Cannabis can utilise light by using different pathways than just chlorophyll.
A purple plant can use light, less efficiently, with anthocyanin.
Red and blue are most effective, but not only spectra used.
Some testing on algae in light is used in marketing by light companies ( plants only see blue and red light)
But a cannabis plant is much more complex.

On the other hand, 10-30 seconds isn't s very long time.
Back yard plants get a lot of pollution from the neighborhood. And they still produce.

I think canna can *see* all spectra, although some less efficiently.
Very weak light for a very brief time isn't much stimulation.

Best to arrange your chores for the light period though, and just let them be if you can.

Before I bought the bulbs with leds in them I contacted company and they said 523nm led are in bulbs.
The two bulbs and they are different shades of green so I contacted company again and they said they change colors over time.

I have seen a few branches closest to light on my SSH plants putting out foxtails on the very tips and rounder leaves with smooth edges.
I hope itís not revegging but itís only happiness with the a few of the branches and what is strange a branch next to it but lower has nice round solid colas with cloudy trichomes.
I am in week 8 of bloom and I changed light to 11-13 for a longer dark cycle.
I donít recommend using green lights during lights off especially cheap led bulbs.
