Did this light cause hermie?

i refuse to beleive that light bleed from an LED is causing that. i have had lightbleed in the past with no ill effects. and going by the previous post with the sun putting out a minimum of 10,000 lumens during the day and we say get a quarter of that during a full moon that is still 2500 lumens, compared to maybe 5 lumens if we are generous for an LED. but we dont get hermies all over the place with outdoor growing.
its either some other environmental factor or just bad genetics is my guess. even when i stressed the shit out of the afformentioned grow i only had 2-3 pollen sacks come up

The led MAY or MAY not have caused it, I just put this thread up to see if anyone else has ever had any problems like this. Then maybe we could have "compared notes".
Anyhow, since the beginning of this thread, i have carefully checkd for anymore balls on the plants. the main one, has slowed down dramatically, but i still pull one off about every 3 days.
I do think it was genetics tho....Was probably a hermie seed. I will find out in about a month, I took cuttings from this plant before it hermied. They are rooted very nicely. I will flower some clones off this and see what happens. lol

the sun is 10000 lumens PER square foot..The moon is .02 per square foot. A candle is 1.

Moonlight is not used by plants. It's "green" light and plants reflect that color of light in the spectrum, hence thats why they're green.

My first round all went hermie and I beilieve it was from a slight glow coming from my clone area. So I very well believe your hermies may have been caused by the glow. I am like 3-4 weeks into flowering the clones from the plants that went hermie and they are nicely budding ladies, with no signs of being hermies right now. My clone area has been moved so the glow is gone.

Trust me, the ac air i am using doesnt have ANY moisture in it. I just used it for a little at a time.

I am completely incredulous about the assertion that the light reflected off the moon is green. The moon reflects sunlight. As such, how or why would it "filter" the light reflected to only that in the green portion of the spectrum?
If the light from the LED did not cause the hermaphrodism, then maybe it contributed, with the hermaphrodism being spurred by a combination of factors.

If you get the hermie problem with any of your other plants try some Dutch Master Reverse before tearing them out. You may have been able to save them...

This is my research du jour. A few things:
First of all, moonlight is definitely not green, (unless the moon is made of green cheese. And there's no way to know if THAT'S true or not...) It's as full spectrum as any reflected light would be, but it's obviously not enough to stress plants. I read (but cannot now find) a Cannabis Culture post from Ed Rosenthal which stated it takes as little as 1 minute of 1 foot candle to interrupt the plants sleep. Even so, this seems more easily said than you might think, given that (using the inverse square rule) a candle at 3 feet is a lot less bright than the moon. A red LED on some equipment is certainly not enough.
Here's a nice chart of light output of various things, for reference:
