When the Lights Are Off During Flower - Is there a color of light to use

When the lights are off during the 12-12 flowering phase, is there a color of cfl lightbulb that I can use without disrupting the plants cycle? I'd like to be able to check on them once in a while.

Green light they say isn't absorbed by the plants. Are you expecting a catastrophe in their dark period? Maybe the plant version of SIDS or something.

It's absorbed, it just doesn't effect the flowering process. Blue would also be safe, just not red or anything with red in it. Blue is farther from red than green so it may be even safer.

Leave the plants alone. They aren't gonna do all your blow when your asleep, nor sleep with your wife/gf if you pass out drunk. And a true green bulb, led preferred. Other incandescent green bulbs are painted glass and not truly green and your plants may respond to it.

Green. Got it.
I prefer to leave them alone, but I when I miss their time with lights on for a day or 2, I want to be able to check on them and stay as close to my current water and nute schedule as possible.
Thanks!!!

Sooner or later you will figure out schedules don't make as much sense as you thought they did.

Absorption spectra showing how the different side chains in chlorophyll a and chlorophyll b result in slightly different absorptions of visible light. Light with a wavelength of 460 nm is not significantly absorbed by chlorophyll a, but will instead be captured by chlorophyll b, which absorbs strongly at that wavelength. The two kinds of chlorophyll in plants complement each other in absorbing sunlight. Plants are able to satisfy their energy requirements by absorbing light from the blue and red parts of the spectrum. However, there is still a large spectral region between 500 and 600 nm where chlorophyll absorbs very little light, and plants appear green because this light is reflected.

Plants absorb green light only a small percentage about 25% or so... This is one of the main arguments for using white led vS the old standard blurple .That small percentage probably isn't going to be enough to interrupt the dark cycle though

No... Lights off means total darkness...those green cfl bulbs will cause Hermie's.

Go a day or 2 with out working in your garden. How I only wish I could go a day with out being in my garden. 5+hrs a day, 7 days a week, 365 a year. Even when I'm sick, or well.
