When to add UVB/UVA lights?

I'm curious as to when I should start using extra lights to output UVB rays. I am 3 weeks into what will probably be a 9 week flowering period. I have three 36w uvb/uva bulbs, I have heard that its the last two weeks that it matters the most, also that you should have at least 100w of special lighting for every 1000w of your normal lighting. Can any one confirm these accusations or have any input in the matter. Thanks!

i don't know what the fuck ur talkn about.. you lost my attention at UVB. i'm even to lazy to read what you wrote so instead i'm writing this.

wow i wasnt gonna post in this thread, but because jack47 was such a dick i figured ill try bring the IQ of this thread up...


I dont believe is that whole only the last two weeks BS. think about it, your using uvb lights to increase trichrome production. so you believe that trics are the plants natural response to protect itself from uvb rays.
well if i was doing that shit id want them on through out its whole flower period, maybe not the first two weeks of 12/12 cos thats a transition period, and maybe not the next two because they are adapting to alot but after that id run it, not if you wanna not run it for the full 12 hours, you could run it for 4 hours at midday, so 4 hours of lights on uvb light off, 4 hours of lights on uvb light on, 4 hours of lights on uvb light off.

about the 10% spectral lighting, i havent a clue where the scientific data backs up that claim, id but them all in.

I WILL WARM YOU.
uvb is harmful that we do know, so dont enter your room with your uvb light on, put it on a switch you can turn on/off yourself, or avoid your grow room while its on.

peace, and dont let idiots like that effect your day

I have a higher IQ than you and my plants are way better than urs... jingle jagle



Guaranteed

adding uvb light may help but not in the way we all think judging by what i have read 'ED" says the higher uvb makes buds of better "quality" but in what way will this express? i wonder? please keep me posted and i hope you have space for a control/ know the strains your running so you can chart any pros/ cons. hope it goes well cant imagine it will hurt. i was thinking of adding back my halide the last two weeks but just cant justify the headache.

HEY JACK47 you were just asking if you can make hash from fan leaves,
now you give jangel shit?
who do you think you are jangel could help you get better but now well whatever
oh and only dicks bash someone asking a serious question,
i had to edit jangel your a bad ass +rep
jack47 your a know nothing joker who deserves to get flamed

Jack47 you are no help, just move on with your day and do a little research if you are so intelligent, nobody appreciates that kind of shit, plus I'm assuming you're like 16 or something...

sorry I was just the kind of person I hate... anyway thanks for your input jagle... the info i got on the subject matter was from Ed Rosenthal and that's really all I have found without going so far into it. I do know the apparent dangers of this spectrum of light and have planned on an external on/off switch, but wasn't sure on the time periods to keep on/off so thanks for that, definitely good to know. Thanks again!

We are talking about lighting not your nuts, besides alot of people must hate you if your plants are getting stolen... I can see I'm not the only one now...

Excuse me Jack47...weak... I don't think so... I think we are all done with you... now go kill some more brain cells or something...

I was asking Joedank. but if you wana insert urself.
How tall is it? pics can be deceiving. how many times did you top it? I know a nice plant when I see it...it remind me of mine. how long have you been vegging?

Mine is outdoor and is 6 feet all and 4 feet wide, toped and highly developed like that. but with nice sturdy branches

Show me.....I say you cant grow a lawn ....show me...and in case you are wondering:



So put up or shut up...cause being an asshole really helps lots huh??


OP I use 2 26 watt 10.0 uvb bulbs along with a 400 cmh and subject them to the uvb from sprout to harvest everytime the lights are on...seems to work swimmingly...hope it helps

Namaste'

Not defending you by any means. Clearly just stating a %^&&$ power point ! LOL
