green light

could someone give me a scientific reason why green light effects plants during dark hours of flowering, as the plant cannot photosynthesise under this spectrum. This is just a matter of interest as the rule of thumb is no light during flowering, even green light. But if photosynthesis doesn't occur under green light then how can it effect the plant? :confused:

Its still hitting the plant with A spectrum of light which is throwing it off, this is just an educated guess....

I've had a similar question. Been wondering if there is a spectrum of light that won't throw the plants off. It'd make things easier, but I don't really wanna experiment unless I'm sure ;-)

There is some green spectrum light that won't effect the photosytesis.. I'm just not sure wich one it is..:o lol

when you see a green light it's all giving off the green color in the spectrum, green chlorophyl is used to attract all the other pigments except green

this is what i think

Plants use yellow light and blue light. Mix the two together and get green.

a pure green wavelength at 562 Nanometers should not effect growth.

The sun produces 58.3% yellow light
36.3% blue light
and 5.3% red light

Average them out and get almost green to are eyes but no green wavelenghts. Green is the balance or middle of the rainbow.

5.3% x 723.18(red nm) = 38.32
36.3% x 508.7(blue nm) = 184.6
58.3% x 616.0(yellow nm) = 359.1
.....................................______
.....................................582.114


582.1 Nm = 5153.6 K (3,000,000/Nm(582.1 in pure light spectrum)=K(5153.6))
Also the suns degree K

Hope this helps

i have read that green light does nothing to plants but are not sure if it will throw the plant off balance in the dark cycle
why would you want a light in the dark cycle anyway?
if its to mess about with them doing what eva the only light that does not affect a plant is uv light (black light)
hope this helps:)

A green bulb in the grow room for emergencies during dark period, but accessing grow room will risk other spectrum light penetrating upon entry. Better off doing everything when lights are on and not concerning yourself with the green light theory.

so a 55k bulb is close to the suns spectrum?

Green light does nothing to plants - Plants absorb light through chlorophyll, chlorophyll appears green IE green light is reflected back at you and the other wavelengths are absorbed! However, plants do possess other photosynthetic pigments other than chlorophyll which could absorb in the green spectrum easily.
