A buddy of mine told me , if I put a green light with my babies, i could look at them in the dark b/c the green light wouldnt hurt them. Is this true?

What kind of green light am i looking for? I found a GREEN party cfl lightbulb at lowes will this work?

I would go with a red incandesnt bulb.
Plants can "see" Red light they absorb it and use it. It will definitely disrupt the dark period.

Green light is "invisible" to plants. They reflect green light. That's why they look green.
Green light is a safe light for plants.

I highly highly doubt that a incandesnt bulb, with a red coating on the glass is going to interupt the light cycle.
Its putting out a red light than we can see, its not putting out a the right red that the plants can use.

Use a green bulb, red will interrupt vegging/floral cycle .Plants reflect green just like SG57 said.
I'vebeencancelld should know better , plants use red spectrum, visible/invisible.

Is that what it is.
i still dont belive that a incandesnt bulb with a red coating puts out the right spectrum that the plants absorb.
Red light that plants use is invisible to our eye.
Red light from an incandesnt bulb, we can see, and do nothing for the plant.

I dont know about red, But I know for sure green light bulbs can be used during the dark period with no problems

Maybe you shouldnt be answering questions when all you have to go on is a hunch.

Do this: Expose your flowering plants to a red light during their dark cycle for a few nights and get back to us with some solid information.

I was always told to use a blue spectrum bulb for veg and a red spectrum bulb for flowering. i dont think a bulb painted red would do anything appart form kill the plants.

They wouldnt be getting enough light. i run on 3 red spectrum 250w cfl's for 4 plants and it works a treat
and for veg i just use 1 blue spec 250w cfl

Have you done this yourself and seen it NOT work?
All you have is a hunch..
MAYBE you should take your own advice.

If that's true, then why are these companies now producing red and blue led lighting assemblies for growth? Just because we can see the light doesn't mean a plant won't absorb that spectrum. Use green.
