How dark does dark have to be?

Self stick weather-stripping around your cabinet doors...

Cheap fast and easy. If you can see light coming out, they can see light coming in.
Could also drape a small dropcloth/ poly over the cabinet doors too. Keep it simple.
Good luck.

I think consistency is more important than level of darkness, judging by how outdoor plants behave with things like artificial lights, moon light, etc. in play.

I get so few males that I actually hope for some more to produce seed. I almost never get hermies. Maybe one or two out of a hundred beans..... I know that I have a pin hole or two in my room. I think that it is 99% genetics.

Again showing your level of skill growing. Any sort of light leak, be it consistent or not, will cause plants to reverse if it's in their genes to do so. Take it from a real grower, with real plants.

Does anyone know what wave length the moon is? if we pout in some moon lits with the corect nm bulbs could we emulate a outdoor grow indoor?

Dark is relative. Light leaks (if any) are the problem.

If you're in an unlit room and outside light shines underneath the door, it doesn't matter how dark the room is. You just trap any light that penetrates.

yes moon light is very dim, almost negligible, especially because plants and humans don't see light the same way. A plant's photoperiod is only affected by red light. See this:
http://mjgrowers.com/book_what_exper1.htm

Having SOME light in the grow room won't be a problem. A lot of the extension cords and stuff I plug in have little dim LEDs which never gave me a problem. The issue here is when you start saying "some," people will assume a small CFL isn't a big deal, or a few high powered LEDs aren't a big deal, as they are tiny relative to the 600w+ the plants normally get. "Total darkness" is in definition a good term because it is black and white, on and off, yes and no. Basically fool proof.

you guys are incorrect. It works like this. think ratios.

sun strength / moon strength
Compared to
1000w bulb / pin sized hole in wall with light coming through

The difference is very large. The brightness of the sun makes outdoor plants hardly recognize any other light unless it's a streetlight directly over it, or something that exaggerated.

Interms of numbers it is as drastic as
100,000,000/10
compared to
1000/10 these are not actual measurements of anything, just an example.
that is my belief also, never had a problem with a sixty watt bulb to check the girls.

for serious, grow anything with sour diesel and tell me that the light from your power strip didn't maker her reverse... lol I'm just speaking from experience. Some plants won't reverse no matter what. Others don't need much coercion, and how much they display their reversal traits depends on how much light exposure they get. My rooms have 0 light leaks. If I have a light leak, my Strawberry Diesel is the first to let me know.
