Good thread, i grow with brand name envirolites and get tons of of thc from the UV light they admit, i got one red and one blue so mixed spectrum for flowering. I know they kick out a good amount of UV light because white plastic degrades to yellow over the space of a year, UV dose this to any material basically, plastic is very susceptable and easy to spot the damage after time.
Plants show a lot of trics under these cfl's and obvious to see the difference. I see no use for the purple cfls, they emit UV light but little else for the plant, versus the electricity cost over extra and stronger yeild it is just plain not worth it for me plus my cfl's kick out more than enough.
When you hang your cfl's vertically as in a lot of pics on this thread they are a fire hazard and not the way they were designed for and a lot of the usable light is wasted, studies have shown that horizontally with a reflector will always be the most efficient use of light from a cfl.
For the average grower is it in your opinion worth it to run some UV lights or just somthing to gain that little extra from your crop? Peace

*its worth it for medical growers since *im epileptic* and i notice a HUGE difference when i implement UV-b on my SAT-Doms strains
..but i wouldnt suggest (for Novice growers) or ppl who just started; to look away from the "purple spectrum" (for now)--->>..need to know basics first before trying the 'weird' stuff --to be honest w/ you.. i dont use CFLs anymore (10.0 bulbs).. mercury vapour or LEDs , cfls made for reptiles are the safest way for beginners to try UV-b tho.. anything in your grow room is fire hazard, (cfls pose less of a fire hazard than HIDs)/ or air pumps sitting on carpets (which isnt smart
).. yea.. i think UV-b is worth being part of any growers list of things to include (generally speaking in-regards to the future... i hope)

Ahh i didnt realise the medical implications of adding UV light, very good point, now i see its application.
I find my 250watt enviros kick out enough UV light on their own, the bigger the wattage the more it is a fire hazard to hang cfls vertically, consider the fact that you are basically hanging your ballast straight over the light, no matter what light you got this is frowned upon, also hot ballasts can be less effective and shorten the usable lifespan.
Anyway i certainly notice the difference in adding UV light, most strains look white under enviros from the UV light, i feel like i have a lot already in my cfl grow and feel that anymore would just be overkill. 500watts of envirolites keeps the UV levels up quite high from what i can tell. A 250watt blue envirolite would compliment a 400watt Hps in my opinion very well and provide a good amount of UV light i think.
Good point about the medical reason for UV lights. Peace

*yup.. i cant see whats happening in there (well, not yet.. havent recieved those microscopes) --even then, its not like ill know for what the hell im looking at, lol..
--but all i know is UV-b does affect this plant, hows & whats are still in Qs ;P

I agree, lots of studies come back inconclusive with the effects of UV on weed plants but it is easy to see the difference by eye with my cfl's. Probably a hormonal response of somekind but who knows.
If i had to guess id say the UV probably degrades the THC down quicker or into different byproducts but wouldnt be suprised if it simply induced the plant to make more trichs to protect its surface form the harmfull UV.
When bugs land on my full blooming trich laiden buds they get stuck and die quite quick, makes for a good bug repellent too. Maybe these trichs will make better sun tan lotion in the future with their UV properties and a decent organic bug killer. Peace

did you do this canna? id like to see results, and yeah fuck the 90's were the bomb! go on rambo they drew first blood!*another side note::
gonna send a batch of harlequin & sour tsnami (to SteepHills) that was just finished under heavy UVB.. hoping to see (if any) does UVB also affect MJs CBD production..

More stupid questions dude-
Isnt the fact that the plant defends itself against UVB light a result that it eventually degrades the leaf surface and can affect it down to a genetic level, hence why it seeks to protect the most important bits?
Why is the tric formation only in the flowering period and not the veg, is this just the plants way of protecting its most prized assets i.e. the bud?
Wouldnt it be wicked if the plant produced trics as soon as it germinated rather than wait till the flowering period. Peace

Oh for sure man, that's how you learn what limits you can push things to. Nothing wrong with that. I honestly don't even remember leaving the original comment now, it's been so long. I really didn't mean to sound like a dick though... I know I can come across that way sometimes and I generally don't mean to. Keep up the good work cw.*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

Anything I can screw into a medium/standard base as opposed to a mogul interests me, particularly self-ballasting b/c I only need supp lighting to augment natural sun in Winter. I have a second floor sun room, all the glass is non-UV blocking. The thread here began with MV self-ballast bulbs, the originals that have a special coating to simulate ozone protection. Some growers actually remove this coating. This isn't something I would even try or recommend for 2 reasons. According to my previous research, mercury-vapor emits zero blue or red and they use a TON of electricity. So I dismissed the idea. The reptile bulbs back on page 8 or so look like they might work. I've also read that the sun emits more red spectrum this time of year, which have my girls getting real potent(will post pics later)at the moment. What I need to do is research further on what % of red to blue the sun emits in December/Jan. I'm guessing more red. Again, great thread!. I am a better grower for having read it.

*glad you found this thread useful
some MV actually have decent amount of blue & red, forgot which company but its the only i'd recommend you.. most MVs are like you stated..--feel free to stop by and check out future updates

1. yes, it is a natural defensive mechanism againist UV-b/pests.. uv-b does affect living tissue (plant surface) but from what ive seen.. MJ repairs itself from that damage, and the THC stalks help block 70%rays bombarding the plant (esp : in flower when thc+ production is in full)
2. trich formation is more so in Bloom b/c this plant wants to protect its precious cargo.. "seeds"
3. that would be cool as hell, just need some genetic scientists and we are set..lol

Hell yeah man. I'm giving the cmh a go around starting next week, we'll see how that goes. I'm going to look around to see if I can't find a quartz glass shield for the reflector, if not I'll just take the glass out entirely. See what all the hype is about.*no worries Wolv, always a pleasure having you around my threads

*yeaaa .. Wolve gettin ' in on the UV-b action
glad to have you on board Sir. feel free to post any results/data you find --ill be using new tools under my arsenal to do a more concise scientific research journal on the affects of UV-b on Cannabis.. --it wont be pretty but im gonna do it anyways
