UVb is between 290nm-320nm. This link tells you how to get'em
LEDs - Gallium Indium Nitride UV, violet, purple, blue, aqua, turquoise, green, white. Also Gallium Arsenide and others. New LED MUSEUM! GaN, InGaN, SiC, GaAs, GaP, GaAlP, ZnSe, flashlight, flashlights.:
Doh!
yeah, get ready to shell out $300-$400 per led. LOL.
thats not at all pricy when you can buy a lamp that emits more light for 10% the cost.... :p
guess its partly due to lack of demand
found some medical bulbs, not leds tho:
Phototherapy Bulb Types & Pricing - UVB Narrowband, UVB Broadband, PUVA - Solarc Systems Ultraviolet Phototherapy Equipment
they have a 36w for 105$
If this whole UVB thing were true, wouldn't people growing outdoors notice that their plants have more THC than when they grow indoors? There is a lot of UVB outdoors.
Has anyone seen or tried a side-by-side on this? Like getting 8 cuttings as identical as possible, growing 4 with and 4 without UVB, then measuring THC? Or is it just people say that they noticed an improvement in THC amounts and/or trichome quantity after starting the use of UVB. Well hello?! There would be an improvement whether they put some UVB in their grow or not. Besides Zcomp says it's not about trichomes, but the ability to convert CB into THC. How can anyone say they have noticed an improvement in THC amounts unless they have the equipment and knowledge to measure CB and THC percentages? I doubt you are going to be able to smoke the two and know which is which from smoking alone. Am I wrong? OK teach me wise ones.
And Zcomp, sorry. It's just a little too stoney in here for me to read all of that article. Is this the conclusion?: The heads or balls on the trichomes magnify UVB, and this makes more THC, which by the way is one of many cannabinoidals (just under 70 at last count).
I was growing side by side and was noticing significant differences and was forced to harvest the non uvb early b/c of problems, still good bud but not far enough along. And now all results are null & void because obvious differences in conditions were most likely the biggest factor, however what is under uvb and should finish up by christmas is the most ridiculously crystallized shit I have ever seen, in seriously undersized pots. As long as you are safe with uvb it is a cheap experiment that I have experienced no ill effects from and am having my best results in some of my worst conditions, still good, just not ideal. All for only a $15 bulb, 2 $.89 extension cords and a homemade aluminum can reflector so for that price if your wondering be safe and give it a try.
Have you grown that particular strain before without uv lights, and notice that with uv you get more resin? Or is that strain usually ridiculously crystallized?Quote:
