Why Total Darkness?

Why does everyone say that a plant has to be kept in total darkness to flower? Marijuana has been on the planet for about 10,000 years, it's never totally dark outside, and yet the plants are doing just fine.

are you talking about when they sleep and having light leaks?

the moon dont have very many lumuns, so it don't effect plants on earth. but when you got a 1000 watter shining though holes in your tent it can cause them stress and they can produce Male pollon sacks

I was concerned about minor light leaks, possibly moonlight, a nitelight, fishtank, opening a door, stuff like that.

Outside plants are use to the intensity of the sun, so moonlight doesn't affect them.

The moon waxes and wanes, rises and falls. it is not as disruptive as a bright light turning on suddenly or a steady and consistent light leak. If you try to grow near a streetlight you will see the difference. It may flower on the dark side but not the side that is lit.

My rule of thumb....darker than a moonless night, and no direct light whatsoever. Direct light (imo) is the problem.

Moonlight is indirect light (don't ask me the specifics of reflected non-polarized light, because I don't know), so unless your plant is overly sensitive there shouldn't be a problem.

BTW - my flower room has several small holes, when the door is closed it gets no direct light, but does get some indirect, and I've yet to see a herm.

Have fun growing

Thanks. The flowering dark area will be, at least until I can get a proper growroom, a windowless spare bedroom. Trouble is, there's a window directly across from the door, and that window is on the sunny side of the house. I have used a piano hinge instead of the door hinges which took care of the light on the hinge side, but some light does get past the door.

the light reflected off the moon dosent contain the right spectrums of light for photosynthesis so none will occur. however artificial light even small amounts of it do contain the right spectrum for photosynthesis so this can trick the plants into thinking they are suposed to be acting like they do in the day time
 
I find that direct light is obviously bad, but weak indirect light is not so harmful. It has to be very diffuse though. All you have to do is tape a sheet of paper between the crack where the light is leaking and the plants, as a safeguard.

I sleep in that spare bedroom, and was worried about opening the door to get in and out. I was hoping that my own CO2 would help the plants, and space where I live is limited.
