I'll also be posting current grows i'm currently working on~~ Indoors/Outdoors/Mars ;)..

**edit 02.15.2013**

This thread is just random discussions on: ultra violet, compost teas, full spectrum--par vs pur, plasma & LED lighting, cannabis genetics, CBD and epilepsy, etc, etc, etc

(some pages are just chatter, so if you have a specific question and dont feel like reading through 200+ pages, just feel free to ask) bongsmilie

:joint: welcome to my ultra voilet (B) guide, im making this new version on the fly :joint:


::::so WTF is UVB? :blsmoke: and how does it affect my mj plants?:::::

*well i like to simply things so, in layman's terms ultra violet (B) is just another spectrum of the sun's light..

*high ultra violet (B) exposure is the reason why we all can't stand under the sun for more than 30mins now..

*some smart scientist stated that cannabis plants react to uvb radiation by producing THC+ (natures way of making natural sunblock:peace:)..

*some non-scientist guy stated that it has been evident in some ninja clinical trials that UVB has a direct link to cannabis potency..
(this im not so sure since having more resin/terpes doesn't mean a higher potency level)

*it has been documented somewheres that mj grown @t higher elevations do produce more "potent yields"..
(maybe the highs felt a bit more "intense".. "concentrated".. since there was an increase in resin, the potency would still be the same for each certain strain.. --BUT there still has not been enough rigorous clinical studies to indefinitely state, that potency is never affected by ultra violet radiation --thats including UVb/UVc/UVa)

*so in theory, supplementing cannabis with UVb would be beneficial since MH-HPS-CFL-etc (all dont have enough UVB output to satify; what cannabis normally would be exposed to in nature)

*recent studies show that genetics also plays a role into how the plant will react to UVB, certain phenos on certain strains have shown a higher tolerance for increased uvb exposure, those certain types combat the increased uvb radiation by 3x THC+/Resin production to protect itself


:hump::hump: :hump::hump::hump::hump::hump::hump::hump::hump::hump::hump::hump:


::::so how can i put some purple lights in my setup? and is there a manual on how to make my plants glow?:::::


*you can go to your local petshop and pick up some iguana lights that have 5.0/10.0 UVB ..those should be good enough if you just wanna have some UVB in your grow room.. keep those cfls close, barely any heat on them, 9inches from canopy is good~

*for those willing:fire:, try adding 1-2 of these bad boys in your grow room (Osram UltraVitalux 300 watt OR ReptileUV Zoologist Mega-Ray 60 watt) ..with these i'd play it safe and put them at 2ft-3ft from canopy, unless you know what your doing:mrgreen:

*please use common sense and safe practice methods when using the lighting mentioned --well just read the instructions that came with them (seems ppl dont:confused:)

*i'd grab these if you are really interested in UVB supplementation..
(www.solarmeter.com / UVB meter.. www.skytronic.co.uk / lux meter.. www.oceanoptics.com / spectrometer..)

*if your wondering exposure times, there is none.. no solid scientific data has been published or mentioned or hinted about how long exposure should be.. if you asked me i'd say try 6-12 hrs on..


(i want my original version from overgrow!!)

*good stuff that you might want to use while UVB'ing your mj..

-tropical organics: banana manna
(helps with the terpene development)

-tropical organics: coco cat
(for the UV stress)

strain list:

-heres a bunch of strains that tested well with UV-b

..nirvana / K2
..serious / AK47
..thseed / mk-ultra
..dutch pass / power plant
..dr chronic / MP5k
..Ken's / GDP
..trichrome tech / purple kush
..southern california / og' (most of the kush strains respond beautifully to uvb, pure/landrace sativas on the other hand need snickers... lol

***any mj plant will benefit from UV-b, im just stating the ones that like it rough in bed, so-to-speak ;)

*found some old pics of my iguana uv-b apps , pretty simple. you can either just hang them near the tops of your colas (or) use a reflector which comes with some of the bulbs. dont worry about burning anything, these bulbs barely get hot :twisted:

*FYI-- the uv-b from these bulbs start falling after 6months, the longer cfl tubes last 9+months.

*try adding 5x uvb cfls (outdoor uvb around mid-noon is pretty the same as 10x of these) ..thanks to the dissapearing ozone layer, those lvls should go higher :)

why not just purchase a CMH? instead of getting these reptile lights that if you dont keep 20" or more away from your plants you run the risk burning the crap out of them...seeing as they burn at a higher temp to recreate a desert environment while supplying the UVB....just get a 400w CMH and use it from start to finish...will replace any HPS or MH...can use it from start to finish..and it supplements more UVB then the reptile lights do...and will place 1/4 of the heat into your grow area that the reptile/HPS combos do. i agree that UBV is very useful and will help trich production as it produces more trichs to protect itself from the UVB light...but why bother with using numerous light setups while putting more heat in your grow area and moving around reptile lights...when you can get a CMH setup..use the same light from veg to flower without moving it every 3 days like a CFL...without the added heat.
just tossing my .02 about UVB lighting

*i agree with you on the CMH instead of CFLs for UVB :) , im just showing the good folks on rollitup what types of UVB setups there are & how they look.
*honestly, ive had 7+ of these small bulbs floating around my colas, and never have i seen any heat dmg/stress from the bulbs (5-8inchs away).. as long as your running fans you should be fine .

its not just the heat they produce...the reason people keep them further away is that as the same to humans...UVB is bad for plants...hence why it produces the extra trichs. now if you have a decent HPS setup i would use 1..2 of the better reptile cfl's to supplement the UVB...but i would not have it close to them. even if they are not putting off much heat...the UVB is just as bad at a close distance. ive been researching UVB lighting for about a year now and i honestly thought the reptile bulbs was a good idea...and it is in the right instance...but i would rather cut out the middle man and go right to the CMH...so far nothing ive seen out performs a CMH...i would put a 400w cmh up against any HPS/MH/UVB setup anyday.

currently: im using these for UV-b Cannabis testing purposes (Mega-Ray ZOO SB 160 watt Self-Ballasted Flood UVB Lamp)

*4x (24hr) @t 1hr intervals during veg
*12-11 hour cycles during bloom (some sativas get 13hrs off)

* i wont argue with you on the dangers of UVB light (that purple wavelength is bad news) haha

* glad to see your on the uvb research end, ive been at this whole UVB & cannabis thing since 1999 :)
* UVB is bad for any life form on this planet (excluding some fungi/microbes)..
* im studying what happens to cannabis when theres 'too much' UVB. Or, a breaking point-- (like how much can an olympic heavyweight lifter max at, period..)

i would imagine that just like in humans it would break down the surface of the plant on a cellular level...same as how UVB causes sunburn it would burn the surface area of the stems and leaves...the stem would probably repair itself...while the leaves on the other hand would have more issues...probably damaging the stomata. which would cease transpiration and cause a whole new list of issues.

*yup, ive seen extensive tissue dmg on the leafs due to high levels of UV-b (but from what i found out by trial n error is that SOME strains have phenos which CAN tolerate those levels :) )

Not to be a dick, but there's moderate heat stress signs all over your earlier pics...

*your input is more than welcome. the pics i posted with the uvb 10.0 cfls does have heat stress & nute burns all over, BUT the heat stress was from the 1k sunmasters @t 1.5ft.. NOT from the uvb cfls.. (early grows, early mistakes).. Lol, gotta love the newbie mistakes, but hey! thats how we live n learn :)

--cool burning bush pic ;)

**another update::

--ive spoken to some local bean breeders that are also using UVB, and 'some' have noticed that the seeds produced by mj exposed to (controlled-UVB) produce smaller seeds (compared to the norm;)..

--if any other breeder knows of this please chime in :)

***ALSO, if anyone has ANY pertaining to UVB/Cannabis, please feel free to post in this thread.

--hope everyone had a good weekend
