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 helpsQuote:

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.
