Night vision/infrared

[SkunkNZ]

If you was to use a night vision camera for security would it have any effect in the flowering cycle?

Yes.

Specifically what? I've been researching for many many hours now...Some say the infrared is beneficial to the Pfr levels, some say it intereferes with flowering, some say it helps, some say it'll hermaph, and yet other say they are using these cameras with no problem...

They emit 850nm IR light. I can't find ANY research on the effects of this wavelength with marijuana, and this spectrum appears to be off the chart of light visible to the plants. But then again, some say the plants can see it, some say they can't, and some say they can see it but it doesn't matter, or might actually help.

HELP!!!!

Thanks,
Jason

PS - yes I've spent many many hours today resarching this. Any opinions or real life experience much appreciated at this point. I need the security the night vision gives, even if it mean point the cameras away from the plants...but would the after glow be picked up? Sigh. I'm so confused at this point I'm going to bed and hoping to wake up with an answer...thanks in advance.

if the cameras don't actually put out any light then you should be fine. every thing emits IR radiation. your plants will put off IR. the camera then uses this heat signature to make an image.

that's the jist of it, you can read some more here.

if you are still worried why don't you put your cameras, even if they are infrared, on a motion sensor? that way you don't have to worry about any ill effects on your ladies.

phytorchrome (the photoreceptor for red light) use red and IR to regulate stem growth and flowring response. red light turns PR into PFR. PFR signals the plant to grow short and stocky stems. IR turns the PFR back into PR.

the plant uses red and IR to measure uninterrupted darkness.

Thank you for the quick reply.

As I explained, the 4 cameras all have 30 IR light emitting bulbs/diodes. They most certainly do emit light, at a frequency of 850 nm. It is not a camera with just a "film" or something, it actually projects a fairly large amount of infrared light onto whatever it is pointed at, causing it to become illuminated in night vision mode. To the human eye, this light being projected is invisible (a red glow can be seen from the bulbs) but that light is most certainly landing on whatever you point it at.

Without the lights on, the camera becomes useless at night lol. So motion capture would then be out of the question unfortunately, but good idea!!

I hate to say it, but Ed's article (which I had found also) is very misleading as absolutely every commercially available night vision camera has the IR light emitters. None of them are the type that "records a photo of the infrared rays emitted by the objects in the picture." They all actually emit artifical IR rays at a frequency of 850 nm, and then are able to pick up the reflections of the artificial light.

Does anybody know how to get ahold of this Ed guy? He seems to be the expert in these matters.

Thanks again for your help, and will be glad to hear any other opinions as well!!

Sincerely,
Jason
