To much BS, this could have been a great thread.
They've probably just discovered HPS and are getting over excited about last century's tech not realising we've all been using them 10/20 years and are on new stuff now.i tried. hard when there are hps trolls
Not to mention that you can get into a nice digital HPS rig for way less than $100 (craigslist). My last one was only $75 (600w Lumatek ballast & 6" blockbuster reflector.)HPS is still hard to beat and we don't talk about the 845 peak and its effect either. So tit for tat really.
I predict in the Year 2000: That we will see IR diodes added to led setups.....Then there will be arguments over which IR is better.....
Are you saying that the 845nm peak in IR energy is by design and not a by-product of the bulb chemistry?HPS is still hard to beat and we don't talk about the 845 peak and its effect either. So tit for tat really.

no...but i am interested in what you think about either scenario....design/bulb chemistry?Are you saying that the 845nm peak in IR energy is by design and not a by-product of the bulb chemistry?
Thanks for the link! I didn't realize that IR past 750nm had that much (albeit relatively low) quantum efficiency. Very interesting.@cdgmoney250 and @Abiqua You guys are bouncing around a few concepts you might want to dive deeper into.
Q10 coefficient of the plants metabolism and the RQE above 700nm.
You guys might like this...

It also shows green/yellow efficiency when as a intracanopy lighting.
I don't know personally in either scenario, I was hoping you might have some insight haha!no...but i am interested in what you think about either scenario....design/bulb chemistry?
. .... IR leds are available in specific nm and will be used in some capacity...my opinion
There is definitely photosynthetic activity from IR in some amounts and I am sussing out other biochemical activities from IR exposure. Also reading the about the Kok effect [sorry dirty birds, probably not what you were thinking] and it how might relate with photoinhibition over 700nm.....I don't know personally in either scenario, I was hoping you might have some insight haha!
I imagine that particular wavelength of IR is an incidental by-product of creating a fuller spectrum by arcing a filament. Just based on the IR regions of HPS, MH, and CMH all having their main peak around the same 800-850nm wavelengths.
Completely guessing here.
That being said, it does appear that at least very small quantities of IR seem to increase total overall photosynthesis. I think you may be onto something with adding IR diodes in the future if technology doesn't take a turn for awesome.
im not saying photosynthesis occurs even as high as 785nm, because most likely IR's potential is in the longer wave section, but what biochemical reactions are happening? Maybe not just photosynthesis, but a process related to photoinhibition as well.....just wanted to put this out there.i have 2 securuty cams in my flower room,785 nm ir but not all the plants get hit with these 2 cams.these run 24/7 but anyhow,i do not see any effect on the plants weather they are on camera or totally shielded from them.maybe its me secret sauce ?
@Greengenes707 -- do you know if they tested for THC levels from both sides in that comparison?DE's system vs PLC system...

You might be right, in other tests when one side was "frostier" than the other, it's been mentioned. I suppose the difference between COBs and DE is not as great as the difference between indoor and outdoor, for instance.Intersting but im guessing these guys didnt notice a startling difference in quality (enough to affect marketability) or it probably would have been acknowledged?
I completely disagree, as COB's have grown some of the frostiest bud I've ever seen while completely lacking in UV.UV seems to be one of the biggest factors in trichome production
Does the Glass included with my reflector block UV and/or Heat?I completely disagree, as COB's have grown some of the frostiest bud I've ever seen while completely lacking in UV.
Trichome production is a secondary metabolite function of the plant and relates to health. UV is not necessary to achieve this.
Explain how jacketed Bulbs in air-cooled hoods (this means no ultra-violet wavelengths) are still growing the dankety dank. Like strains testing out at over 30% cannabinoids.
