The purpose of this thread is to learn once and for all if there is any merit to this UVB. There are people firmly on both sides of the argument.Throw that uv crap in the garbage!!!!! It doesn't work its a myth that's it!!!!!! It does not increase secandaries one bit it only damages them and decreases don't waste your time or money period
The technicians who run these "studies" for Fluence etc are people happy to set their credibility on fire for a paycheck.I agree there is alot of bs out there but fluence has done tons of research on this very topic and it's a fact uv damages DNA of the plant.. And also was reading new evidence that blue light makes the plant do the samething as it does with uvs and all about reds.. But you also should be pulling the reds 1-2wks to chop and you can get the same plant response but non of the bs..
I'll post the paper when I get it from fluence as I would love to check it out for sure.. But they are not the only ones who has done studies either... But it is awesome your doing testing like this though....keep up the great work...
If you like reading studies, i linked a great one here. http://milsonmilson.me/index.php/2021/03/02/uv/It's all good I hear Ya and I agree which is also why I said I'd love to read the research they have and hopefully can get it but will c on that one Def not holding my breath...
And scynceled has a paper they are coming out with that will back it up as well.. Well from what I've heard but I'll believe it when I see it and all of it.
We only have a couple weeks before we get some results. Let's see how this plays out.You hit it on the head with a hammer on that entire post I agree totally about all of it lol... And ya me too I'm just a personal home grower who does it for my health and for the love of the plant so ya Im down w testing wise I do not have any uv meters but we can also share data since we have the same setups well the uv and size tent as I run leds
So for this test we are trying to hit just the last 2 weeks of flower. This is wisdom that has been repeated on the forums many times in many ways. There is, forum wisdom would say, a paper somewhere that asserts that adding UVB in the final 2 weeks of flower improves THC by up to 4%. Where this breaks down is that I cannot find a report that uses this technique. I also cannot find the amount of UV nor the photoperiods other than inside forum posts.Sweet well I might have to do this run w the uv after all starting flowering in a few days so I'm down and p.m if u want to discuss details and what not too
Thanks.@Moe.Red here is a bulb meant for the last two weeks. They used to have single ended version. There were tests and reports showing the 4% average thc increase and claims of increased terpenes 5 or 7 years ago when I was researching this stuff.
Can not find them any more either. Or much spectrum info from university of Michigan from the hps vs mh days.
search engines may have the results many many pages back I guess.
it’s pretty old info now. The solacure guy seems to have the most info anymore.
sorry I was hoping to post something definitive for you. Everyone was proving this 5 years ago. With led having no uvb I guess the info had become buried.
