dude. it's all good. that was the very first thing i was told to do!! it's just a street myth. stick with what the guys on here tell you. I've never faultered following advice of the guru's of this site! hps, mh, and flouresents all the way!

Im pretty sure they use black lights for growing in movies bcuz it has a sick effect

dier knows what he is doing. He also provided results from 2 instances of his own grows in which 1 had a blacklight and he claims that was better. He isn't saying it will work alone but in addition to what you are currently using. I have heard many people talking about using UV to help when flowering to make better buds. I saw some at I think walmart and I might just get a small one to add to my closet just for grins. I doubt it will hurt. The only reason I am even seriously considering it is because dier said it helps.

All you ever needed to know on UV

Someone posted a link earlier in this thread to some research on UV light and MJ. I don't think blacklights would work, but a Mercury Vapor lamp might be a good thing to look into as a supplement to CFL, HPS, or MH lighting.

Just in case you don't wanna go back and look for it: http://cannabase.com/cl/bcga/bcga/uv.htm

there is a $50 10.0 uvb light at the pet store for reptiles that you can buy, it does make more thrichomes during flowering. i'd imagine that using a little dinky black light wouldn't do shit. but black lights only help if you already have good lights.

damn i made this thread 4 years ago - I must say I never thought someone would have posted a reply just a couple days ago - thats pretty crazy - I must admit now, that a black light will not work haha

i got a black light in my room and some sweet posters but ehh ya no good for growing

[gonejah17]

yeah its never wrong to ask questions but if u read/research a little ull answer the questions for urself and not have to ask something that others might think is stupid. It's SO true that its human nature just to ask and not put in the effort to find out for urself. I guess it really depends on whether or not u care how u portray yourself to others.

Here's a question. Just curious, I know u can use green lights to light up ur grow area during the plant's sleep period without disturbing it. Can u also use blacklights?? no i didnt read or research cuz I couldnt give a squiggly pig shit what ppl think about me lmao

Hey guys, Im just wondering, I have heard a few different answers, does anyone know for sure if hitting your plants with UVB during flowering with make more trichomes or is this just a myth/ ignorance? Thanks.

[Grassmann1]

I would give it a shot, who knows what you'll come up with

[420Grower420]

I keep hearing that black lights do not increase THC and that to even try it you have to buy a black light light the reptile owners use and they are expensive.

about 6 plants per square foot i think i heard it was?

dont quote me on that last part, becuase the thing i read was very vague

i thought one plant per sqft?

a black light is not a uv light, uv is on the color spectrum you cant see it, it is past the black light point
