UVB BULBS

You have been using it for 10 grow cycles, and dont have any additional insight to add yourself, yet bitch at us to provide you more? ROFLMAO.

I really could care less about your being the OP, as it was your previous post I found to be antagonistic twords all members that did post what they could contribute, but obviously didn't provide the insight you crave. So again I ask...exactly what have you added in bitching about the death of this thread, and the lack of fresh info, that may spark someone's interest in furthering your insight?

I personally have stopped adding to any UV thread. (a request from my wife, who suffers from cancer herself) Not that I don't trust the membership's maturity and diligence that using these spectrums requires, but I'm not all that certain I would like to contribute to another's half-assed approach to growroom safety, which can result in blindness and/or cancers. (not too sure about civil law, but I'd bet there's liability laws to considder as well)

Having said that, good luck with your endeavour.

Actually I never asked for any info and do not get where you got that idea from, I have all the info I need, I have experimented with different bulbs, the amount of uv, distances from plants, different starting points etc. and did not ever ask for more info, as I have already written an entire report on using uv for increased potency of your final product that I compiled through my experiences and my knowledge of horticulture and uv as I started testing this w/ marijuana as a result of research I completed previously at work and it's just annoying seeing people not only beating a dead horse by repeating the info in the same thread over and over but then basically claiming credit for methods posted previously in the same thread as there own input, if you start at page one like you always should before "contributing" to a thread you would see that everything mentioned was copied from previous posts and the only new info was a way to buy a more expensive bulb that requires you to do just about everything a cautious grower would not do, i.e. paying by card online, signing your name to a waiver, saying you are using it to grow with(regardless of what you say you are growing)etc.. So I mentioned that the info was previously posted so others can go back to when this thread was more active with new info and get the info from the original posters instead of the incomplete bits and pieces of the post being discussed, I really don't get how you could have gotten so offended by that but I guess some people are just a little sensitive, I still think it is funny that somehow you read my post as me wanting more info from someone who won't even talk about uv and someone who copied what I and others wrote, I do not crave any insight lol I really could not be happier with my continued success that I have been able to repeat every single grow.

As to liability laws, there are no laws that would allow any civil action against anyone in this situation in particular as the law specifically does not allow any civil action to be taken against someone when what they are doing is illegal, unclean hands, you can not have civil liability for someone being hurt b/c they used info you posted on a forum on how to complete or improve an illegal act, and beyond that the liability laws for posting on forums are pretty much nonexistent and the precedents set by previous rulings would suggest that there would be zero civil liability, of course then again you still have people who have things like "everything I post is a joke and not true" etc. in there signature and they actually think that would cover them in some way and that is just hilarious.

Anyways my whole point was to get people to go back to the original information and quit repeating the exact same things over and over if anyone has more info of course everyone would benefit from it, but there is no benefit to repeated info or suggesting people go out and by bulbs they have to sign there name to. And there certainly is no benefit to this back and forth b/c you were somehow offended by me mentioning this, this is exactly why I stopped checking cannabis.com for so long, too many sensitive people who are sensitive to the wrong things, instead of being sensitive to people taking credit for info others have already contributed or the fact that someone is suggesting people go out and sign there name and sign waivers when purchasing growing equipment.

Good luck with your grows and next time you get so easily offended by someone who isn't even addressing you, smoke some of your product and relax before ruining a thread with back and forth claiming the person who started the thread and posted nearly all the info that was claimed by another as not contributing to there thread.

hey now guys dont clown this up now, keep it on track!:thumbsup:

How dangerous is this UVB & how many watts(?) for most efficient thc production when supplemented with HPS to reproduce the blazing suns of the equator? Landrace equatorial sativa's are quiet special no doubt(columbians, panamas, thai's, etc.) could it really be the UVB responsible for there behavior? Posters who've "preformed tests/experiments" what are your results on what strains & you better have a variable and efficient Hydro & c02 skillz.

Unfortunately I can not comment much on strains b/c I first purchased a bag of indoor mix seeds and all the seeds I now grow with are from plants from that original bag I bought a few years back.

UV-B can be very dangerous to your health and it can be a silent danger b/c it is not as if you open the door and check out your plants and you feel it, you can hardly even tell it is on, but that is one of the dangers of it, UV-B can be used safely as long as it is set up so that you and the uv-b are never on in the room together, it is just something that is not worth the risks of how much is ok it is better to assume none is ok.

I have always used two of the reptile uv-b I use the 20w cfl 10% I believe it is, I purchased them from petco for like $15 a piece and I have them on for like 4-6hrs starting just before flowering and slowly increasing the time they are on so that I do not run the risk of frying the plants with too much uv. Research that I have found online, I found a great 25min video that I can not find anymore, does suggest that strains that would normally grow closer to the equator do tolerate the uv better and have a higher increase in trichs when compared to the same strain without uv-b. While I do think the uv helps those strains I don't believe this has as much to do with it as genetics as one would assume that even the better reaction to uv has to do with the genetics on the strain, however the genetics can also be affected by the region it is native to so it may also be a chicken or the egg type thing as well.

As to the hydro and co2 I always grow in soil, I just prefer it, and I have not ever used co2 in my grows and I have had great results with the uv-b and that is one of the reasons I like it so much. I actually started using uv-b before I completely mastered all of my techniques and I saw "better" bud from the first grow I used it on, which is one of the reason I really started to believe in the uvb.

Hope this helps answer your questions and thanks for getting the thread back on track.

My Ceramic Metal Halide Bulb puts out enough UV rays to burn my knuckles on the back of my hand...and that's just from rotating the pots...couple of minutes each day...beware....:smokin:...wear your shades, too!

ditto on the safety concerns ... I'm pretty blind in my right eye now, happened suddenly, over only a few months ... I think it's just a cataract, which can be fixed, thank God, but I won't know till the eye doctor checks it out ... am curious if has anything to do with my lamps :wtf:

Hey Dutch,

Recently while looking for a CMH bulb, one of the mfgs (don't remeber which site) was stating they had "new and improved" glass envelope that cut down the amount of radiated UV.

How is that an improvement?

Everything that I know about CMH bulbs is in here...(and the ICMag link included)...you should be able to read it all...in two or three days...:D...
http://boards.cannabis.com/indoor-li...-ballasts.html

What makes you think I haven't already read it.....
....and it only took me a week. lol
Actually it was you that got me interested in them, you seem to have away about Pimpin' good stuff.

I'm not looking to change anybody's mind...I just want them to see the light...:)

Just b/c the uv might help cannabis it may not all plants, also safety is again a concern if you are in the room under that light while it is on, esp extended periods. If you add uvb separately you can turn it off and enter the room safely with your main lights on instead of during there dark cycle risking letting light in. So it is an improvement to not have your main source of light admitting as much uvb. Hope this helps

That was sorta a rhetorical question.

I understand exactly why a mfg would be lookin' to make thier bulb safer, for the general idiotic public to use.

I had avoided this UVB bs for a long while, but as a user and believer in UV felt compelled to comment at some point. I had avoided it because while I know I hold no civil liability for an idiot's misuse, I felt a moral obligation not to get people involved in something that held a very real potential for harm, and might hurt them.

Check my posts here, I preach safety.

I came back to share a good thread I found on UV bulb experiments but Geezus what a tough crowd... fuck this... Thanks the few friendly growers who have something positive to say but to those who shoot a guy down for poking up his head... Wow. Smoke some more weed already.

No wonder I don't come 'round here no more... Excuse the fuck outta me for trying to help out.

Even the assholes out there can check this out though, it's an equal opportunity thread... I do hope it helps the few who really want to know more.... or excuse the fuck outta me for the omniscient ones. Sorry to waste your time.

Peace!:hippy:

Yo' Gr8budz4me,

First if you are interested in 10k bulbs, there is a company making PSMH bulbs in various Kelvin tempertures. They are designed to work in digital and electronic ballasts. Thier recomendations for various temp bulbs for various stages, is interesting. Here's a link to them, Sun Pulse - Home.

Second, I had to look back thru the thread to see wtf you were talking about. Ok one guy (the old Rusty) gave you a hard time, but that was literally 2 months ago...let it go man. If you spent more time here lately you'd see a new Rusty who is trying harder to temper his responces to folks. While looking back further I saw I was pretty harsh to Dogznova, more then I needed to be. I too have been trying harder to be more "user friendly" with my posts. I figured out a few months back that part of the problem is we all have certain passions about how we do things, and there are so many growing styles with varied techniques that what works for one person might not be right for someone else. Toss into the mix controversial topics and well you can see what happens. We all need to try and work together, after all we all share one passion, growing mmj, and that should provide for a large tent.

Back to UVb, I have always been a proponent of it's use, tho for various reasons avoided the topic. Someone who's opinion I respect, Weezard, holds the opposite view that UVb does not add anything and is in fact harmfull to plants. We talked about it, back and forth, and I had to admit it was a long time since I did a good back to back comparison. So I decided to try a run without the UVb in my personal grow. I'm about 5 weeks now into a run of White Rhino and I am not using any UVb this time around to see the differences. And I'll let everyone know those results in another 3 weeks or so. But so far there is not much difference to report. The plants seem to be packing on the trichomes at about the same rate as before, just like you would expect any of the white strains to do. We'll see tho what the outcome is.

Hay oldmac.... Weezard is exactly correct.. BUT the problem is UV-B will produce more trichomes, but only because it's a defensive light. From my understanding the reason for her producing more trichomes (using a defensive light) is so the flowers can catch more pollen because she feels threatened. UV-B light actuly deteriorates THC production.... The truth will come out soon..

Your better off building trichomes with a different light that does not deteriorate THC production like UV-B will.

Old mac your on the right track by doing a good side by side comparison. :thumbsup:

Hey Dog,

I have a feeling that my back to back experiment is going to probably lead to another dealing with this first aspect. I've started to think tric production is really a function of genes more then what light is used.

About 10 months ago I got some cuttings from someone who was using a mmj plant that seem to have a lot of the properties desired for cancer patients; good nausea control, stimulate appetite, and had good pain control properties, all without the heavy couch lock effect. He would not tell me what strain or crosses were used but because a patient I had seen moved to his area and was now using it I was interested. We nicknamed it "apricot" cause this fellow was into alternative medicine and was promoting the use of apricot seeds as part of his treatments. When I got the cuttings he told me that the tric production was low, hence THC was less then stuff I had been using, not to be concerned. All I thought was, let me grow this and we will see about that. Well even with UVb both as a supplement to HPS growing or when using the TI pro-blooms this stuff will not put trichomes onto the leaves they only form on the bud. This has been the first plant I've ever grown where the leaf trimmings were so deviod of trics we throw them out. Could not get any kief out of the trim, made me start to rethink, does UVb really add to tric production.

First we'll see what happens with this first experiment, then I'll see what needs to be compared next.
