Why doesn't moon/star light cause problems?

[BerndV]

The amount of ambient light outside is significant, particularly when the moon is full and the sky is clear. Why doesn't this cause the same problems as minor light leaks in an indoor grow? I've never done an outdoor grow and have wondered about this for a long time.

Who says that it doesnt to one degree or another.I firmly believe that to optimize indoor growing trying to simulate the outdoors in not your best bet.You'd do better to use all the best indoor techniques and experiment with these and different strains of course.I growindoors and the absolute only thing I care about out there is a storm knocking out my power

I think it has more to do with the ultra-low intensity for the perceived brightness.
There are simply not enough photons striking the leafs surface to provide the required excitation energy to transfer the electron and thus perform photosynthesis, known as the Hill Reaction and in concert with the Calvin Cycle.

Starlight/moonlight are both in the visible spectrum.

The intensity of moonlight varies greatly depending on the lunar cycle but even the full moon typically provides only about 0.2 lux illumination, so the full moon is about 500,000 times fainter than the sun. When the moon is viewed at high altitude at tropical latitudes, the illuminance can reach 1 lux.[2] The color of moonlight, particularly near full moon, appears bluish to the human eye compared to most artificial light sources. The Moon's albedo is 0.136,[3] meaning only 13.6% of sunlight incident on the Moon is reflected.

Although I've always been very vigilant about ensuring zero light leakage in my grow room, one often hears about people having problems with hermies, etc. due to light leaks. I can only assume that the amount of light entering during lights-off must be substantially greater than that which occurs naturally in outdoor grows. No?

I'd say the huge majority of hermies are not environmental hermies at all,but genetic hermies.A good rule of thumb for an indoor flowering room is you shouldnt be able to see your hand in front of your face at 12-18 inches.Green and blue diodes are fine but red is not

^^^^^ exactly. i do have a strain that didnt hermie with red light when the black tape fell off the powerstrips.

I think some strains are more sensitive because of where they are from.A plant from the equator that gets longer days might not be a s prone to hermie as a northern strain that is used to solid dark periods.Just a thought anyways.And some genetics just get screwed up along the way and are always more sensitive.

Oh and the light coming of the moon is just a reflection from the sun so it may seem bright but it is really weak.And starlight comes from way far away and is super weak.It takes something like 40 candlewatts for a plant to recognize the light.

Spectrum has nothing to do with it, it's half a freaking lumen, it won't do anything to your plants. Haven't you ever noticed that visiting a grow room once and a while wont hermie your plants? Same principal, not enough light to trigger that, maybe it caught fire, then it might do something. oh so high,

It's just not enough light to cause hermies, that's all. It's like if you grow 400 feet away from a lamp post, it probably wont effect your plants. Best not to, or at least have them hidden from the excess light. I don't encourage growing pot or doing anything with a candle unless you're using it to light an ital wick, but if you put a couple in your grow space, your plant wont hermie. Remember, candles (per-area) is also a unit of measurement.

I have a dr 120 tent and leave the velcrow flaps open on the sides 24/7 for vent's, Havent had any problems by doing this, Ive also seen a pic of an out door plant thats under a street light, Half the plant under the light is veggin still the other half in the shaded part is flowering
Hermi's is in the genetics, Pin hole light leeks arnt going to bother your plants at all

I'm no expert but I totallly agree with this one
This is a great question and answer
