Using Green Light in the Dark

Would this make a good light for working in the grow room while the lights are off during flower? I have heard you can use green light when it is suposed to be dark and it wont interuped the schedule of your ladies. Even using this scares me though :-? I dont want to stress them

Also since this light is a CFL, Does that mean it wouldnt work? All the lights that i have seen that are green have be incandecent bulb. I would assume this is because those type of bulbs are worthless as far as growing. I hope these will work because they are cheap and they use almost no power. Thanks for your time :)

You have 12 hours a day to do what you need during flower, use that time to do what you need and don't waste your time trying to think of plans that only cause problems.

I haven't seen a PAR curve drop off significantly in the green range.

But I'd use a green flashlight or use that bulb well outside of the grow room. Keep the amount of light dim.

(remember, us lowly humans are 'tweaked' for green, so little is needed to do our tasks, so a little does it)

Now that being said, why do we use red lights to keep from the night vision syndrome?

True. It is kinda an emergency type of thing. I just want to be able to go in if i have to.

Think of it this way, green colored light is invisible to plants because they are green. Why do you think we veg with BLUE and flower with RED. The plants cannot use any light from a green bulb, so they think they are in total darkness.

The army uses red/green light because it does not glare when shined on something reflective like glasses or scope lenses. Thus not being able to be seen from afar from a simple reflection off of standard military equipment

I use my green light in a mechanics light with a lampshade on it to keep it very faint.

Ok I see. So you havent had any problems with your plants with limited use but no one has like tried to like have your plants on 12/12 with the hps but during the dark period just have a green light constantly in the room just to see if it jacks stuff up?

unless ur using like green LED lights that only emit one wavelength of light? ... then the light ur using may appear green but likely emits other colors as well. EG; you could put a green filter of a normal flashlight and it would appear green, but is still emitting almost the normal spectrum i believe.

all a green led is is the electrode encased in green plastic if its wasnt colored itd be a white light

so would this mean that the light is still valuable to the plant or does the green filter make it so that plant doesnt see it??

Could you do the opposite? By using only red and blue CFLs instead of only whites, could you increase the efficiency of CFLs? Isn't that the whole reasoning behind LEDs?
