do green bulbs really work?

Is it true you can use a green lightbulb in a flower room while the lights are off and not disrupt the 12/12 light cycle?

Sorry didn't mean to post twice (took awhile of my 1st thread to post) how do I delete this one?

Go to "advanced', and down at the bottom I think you'll see the 'delete' option
Nice catch dude, it happens........
But ya, I answered in your other one, yes it should be OK.

I run 2 40w shop lights with very low spectrum I don't care for the green lights which I've done before, I haven't noticed a difference.

The green lights don't actually do anything for the plants. They're invisible to them so it just makes it so you can see without disrupting the cycle, but yeah they work great. I have a green LED headlamp that I use whenever I'm in the room when the plants are in flowering.

Thanks for the info, all I'm looking for is a way to see around in the room while the hids are off. Any idea how to take pics while the lights are on without getting that annoying interference (bars running across picture)

If the lights are off you won't have any interference. If it's the dark cycle and you're taking pictures just make sure you take the picture without the flash, even a second of bright light can have adverse effects on plants.

HPS lights will make those crazy lines, although I've never had a problem taking pictures with my smartphone camera while the HPS is on. If it's during the light cycle and you're trying to take a picture under HPS, just turn them off and turn on a regular light.
