do plants produce thc in defence against uv ?

Penis nose? Now wouldnt that be handy!!!

I took a couple plants out from under a 1000 watt hps and finished them the last 2 weeks under a 400 c.m.h. The color change was awesome and everybody raved about the bud. FWIW.

I thought most HIDs used glass that blocked uvb? I was planning in running a couple of T5's if I can find 4' ones.

the glass from reflectors is what blocks the uv rays, I use a open hood. Probably not a lot of uv output, but I think just using a blue spectrum closer to uv may be helping.

Not sure if thats strong enough to much. Have you looked at reptile bulbs?

better yet, get one HPS and one super blue MH bulb, that'll put out waaay more lumens than the reptile light, plus you get the added benefit of the blue spectrum as well as the UV

Any Updates on these UVB bulb grows...i have a 24inch 10.0 uvb reptile bulb and i was wondering the effects it has when flowering,what hours to use, and how close to use them

Use it during veg and only a bit of flower so you don't degrade the medicine when it finally starts growing. UV Bulbs are very strong as they are for cell development ZOO MED REPTISUN 10.0 is the way to go! Seriously.
Pics soon yall

SPOILER ALERT! I remember a controversy from some time ago about this subject, it goes like this:

Yes, it's true UV-B will increase resin production (presumably for protection). The controversial part is that an increase in resin production does not neccesarily translate into an increase in THC production (potency).

Some "experts" insisted that they are one and the same, while others contended that they were two seperate functions (that operate independantly). I don't know, for certain, which side is correct, I've never done (or heard of) a proper "side by side" test. It is "logical" that resin = THC - but is it true? Maybe somebody has more than just hear-say to settle this matter once and for all!

I know I've smoked some pretty "Frosty" buds that weren't all that potent, and some non-frosty buds that knocked my dick in the dirt!

UVB rays are responsible for causing most skin cancers. While large doses of UVA rays can contribute to cancer, it's the UVB rays that are commonly to blame.
If you've heard the advice to stay out of the sun though the mid day hours, it's the UVB rays you're trying to avoid. They are most prevalent mid day, so if you must be out at that time, protect your skin.,,,,,,i got this on a site,,it looks like its the uvb rays that are dangerous and that's what the plant is trying to defend its self from? i hope ,, keep digging boys,, our lifes are at steak!

sorry about the penis insult, i thought youd read the thread wrong, it turned out id read your post wrong, opps ,
whos the penis nose now, , didn't you watch the youtube vid about how uv works on the tricholms, it makes sense and alot of people do it without knowing with mh lamps? Adding uva light is just like a light booster, i suppose if you want to understand it you'll have to work out what role uv light from the sun plays on earth, we know what the other colours do, and uv is there for a reason, reptiles need it for some reason, but humans don't need it so we get a tan in defence, not only to be able to tell if a chicks been wearing a thong! There's a reason its there ,,, hopefully to get me more stoned, but ill settle for the thong detector?

great video, but i have one gripe, if u run a uvb light 24/7 your plants will hermi nearly 100% of the time i think he must be misinform about that part. Flowering plants need their darkness. But i have heard of people getting great results running them for like 3 hrs every time the HPS runs.

he says dont run it more then a few hours mid light cycle in flower stage, as far as some of the dankest buds I have seen they all have uvb on them. way more crystals.
