Hi growers!
I've been reading this forum for ages but this is the first time I wanted to post something.
So as a grower we all know that purple color coming from a grow room, which if you didn't seal all of your windows correctly can start to cause suspicion. This can of course be remedied by using CFLs, HPSs, etc, but still the problem remains that having a light on consistently can look suspicious! But I digress.
Basically the purple color of grow lights comes from (as many know) the combination of red and blue light, of which plants are best at absorbing and using for photosynthesis. However plants (cannabis in this case) do not only absorb red and blue frequencies, and will absorb most of the spectrum to some degree. For this reason, could it POTENTIALLY be possible to make grow lights using light wavelengths JUST outside the perceivable spectrum. That is, infra-red and ultra-violet light.
Obviously since the absorption spectra aren't centered around UV and IR light, more power would be needed to produce the same effect, and because of that more heat would be produced so more ventilation may be in order, but the point of this idea isn't for efficiency, it's for discretion.
Clearly since this idea isn't on the market there must be some reason why it wouldn't work, either conceptually or logistically, but y'all let me know your thoughts, I'm exited to hear them!
TL;DR - can grow lights be made "invisible" by only using UV and IR light?
