In my experience lighting is the most important thing you can study. The first 5-6 years of growing i spent all my time on studying and tweaking nutrients. I learned a lot but i wasnt seeing extreme changes to the product like i wanted no matter what i used or mixed together. Then in the last 4 years or so i went to a simple base and boost nutrient regiment and started messing with lights, color, intensity, fragment and direction and i started having some breakthrough changes in the product. I studied what the sun had and tried to mimic it. It is impossible to get the intensity of the sun but it is possible to put a spectrum together that is close to the sun. The reason i started this was because i always heard people say that OUTDOOR IS ALWAYS BETTER. Started looking at what many growers use for nutes and didnt see any breakthrough product they were using so one day i looked up!!!! Changed my life and the meds i make forever. I can take plants that people hate due to bad quality and i can turn it into a gem now. I compiled these charts, websites and the download because it really gave me a firm grasp on photons and the purpose of the trich. Now i hope to pass on the knowledge to people so it doesnt take people years to learn what i learned.I am just now experimenting and getting ready for in depth study of light after 4 decades of horticulture and plant experiments and studies I have never dived deep into lighting.
Years ago on this site I was blasting plants with massive Gamma Rays creating mutants, ppl thought I was nuts. I spoke of argon lites and CFL lighting, Farmers thought I was crazy. I was laughed at so I left that thread also.
Then I came back to another thread speaking of UVC blast to kill bugs yrs ago, again I was laughed at.
Anyway IDK anything about lighting so Ive done some wacky lite experiments. I realized we dont understand light as I noticed many 1800 light invention devices that we still dont understand to this day. I posted the break through in the Crooks Radiometer to demonstrate that light is not understood on my seed 2 seed thread.
So Ive been maintaining a few small gardens, IMO it seem like the LED gardens THUS far have not had mildew issues. I dont know this to be true and more of question . And is there high UVc in the normal LED grow lites? I notice the possibility of infrared spectrum in diodes, IR in LEDs? Lots of IRs in LED? One of the gardens that I helping with had a VEG and BUD switch set to ON. the lites were ON and in a 12 hr cycle. I turned off the VEG spectrum switch and after 1 day the leaf stems were fire red.
sun seems to not stop PM once its started to stay on topic. I'd assume the sun has high UVs. Ive put plants outside that have gotten PM and it does not help slow or stop mildew in Colo environments but yet Ive seen experiments in videos where UVc will kill PM on blueberries. It must be the doses of UVc that killed it, not sure on that either.
And with out light scopes and the fancy apparatus I cant get my prisms to separate crap. I guess I have to break down and buy that equipment , But I heard some new Android phone apps will break down lite spectrum so I hope that happens soon, maybe these App already exist. I didnt find any Spectrum Apps last I checked. Ive given up Apple Apps, they suck, the selection and availability sucks.
Sorry guys I get OCD on threads,, get off topic and I almost posted a pic of the 500 lb gamma ray blaster.. :nailbiting:
I sure hope not. UVA led sources are relatively common and cheap however the shorter wavelength devices are quite expensive. Of course, someone could put a phosphor on a COB that would emit in that range if they can get the proper energy stimulation source ( I'm not sure just how they would do that, as you lose a bit in the conversion so at best the efficiency would suck balls ).And is there high UVc in the normal LED grow lites?
Depends on what you are trying to do. If you want to kill or mutate terrestrial life, that'll do 'er. I don't think it is useful for much of anything else.I was blasting plants with massive Gamma Rays creating mutants, ppl thought I was nuts.
Ive seen some UVC lights sold by vendors at cannabis events that eliminate mildew. Ive seen these UVC lite device for blueberry and other crops. They have warning signs on them for eye protection.I sure hope not. UVA led sources are relatively common and cheap however the shorter wavelength devices are quite expensive.

One should pay close attention to where our atmosphere attenuates ( filters ) the spectrum. Also, the shorter the wavelength of a photon, the higher the energy ( why shorter wavelengths damage DNA ). Ag science did not seem to pay much attention to UV exposure until we punched that hole in the ozone layer. That lead to many studies, but most of them focus on UVB, UVC ratios and neglected to even use UVA components, critical for plant recovery from the shorter wavelengths. As a result, they saw massive die-offs and well, it painted a pretty bleak outcome from borking the atmosphere.
I'm still of the mind that UVC sources never should be used without saftey interlocks to prevent exposure. The effect is insidious, ask anyone who has suffered from 'welder's burn'. You don't feel the sunburn on your eyes until hours later, after the damage is evident.
Thats exactly what I did, I built a ""Breeder Reactor"". I like that David Hahn already. I did the same thing he did . I got some lead blanket and did made some crazy azz plant breeds. I shot Gamma's in embryo, grafts, pollen, I freaked some plants and forced pollen crosses. Mine was much easier to build in 2010,, I used a projection TV lazors.Depends on what you are trying to do.

UVC is largely attenuated at the earth's surface, we would be here if it wasn't. There is little good that comes from using it for anything but disinfection.
I think we are suggesting here that using some UVB ( probably no shorter than about 300-305nm ) and about 10 times that level ( recall UVB is pretty energetic ) of UVA to more closely mimic measured Solar emissions at latitudes where cannabis thrives ( and even that depends on the strain ) and produces desired potency for numerous factors ( THC, CBD and terpenes for example ) is what we seek.
Personally, if I were to want mutations - I'd use colchicine. At least then the results would not be random and probably unexplained. When you first mentioned your experiments this jumped to mind: https://en.wikipedia.org/wiki/David_Hahn
About the only uvc light i recommend is right here... you plug it into a duct.. i dont even recommend the wands because people use them too much and in very unsafe manners. Without proper safety you will get cancer.Ive seen some UVC lights sold by vendors at cannabis events that eliminate mildew. Ive seen these UVC lite device for blueberry and other crops. They have warning signs on them for eye protection.

http://www.uvonair.com/ 250 bucks for the 8in in the picture. Other brands have a unit that goes in the duct but dont have the case or service door. These are the same as the water filters too.So - got a URL for where ya get that duct section? I can see they use quartz tube arc, if that includes the power supply... geez prolly not cheap either... But I usually buy one of something I find pretty interesting to satisfy curiosity about possibilities.
