UVb an experiment

[knna]

Results of experiments are always open to interpretations. But in order to attribute an effect to one parameter, as the blue light in this case, it would be required that the parameter varies from the control to the other conditions tested.

Usually, experiments are designed to keep most parameters constant in it and vary just one parameter, and then results are analyzed based on the varying parameter. Attributing an effect to a parameter designed in the experimental method to be constant, as in this case, is hard to understand to me.

Maybe Im a little short minded and I cant see a casual link that others thinks is evident. In my humble opinion, again, I dont think that saying weight gain was due to differential blue content is a fair conclusion to experimental method and results of Oldmac. If some genius is able to identify by his results that the lighting was not fair, knows exactly what chamber had more blue in it, although designed to be equal, and negate the effect of the main variable parameter tested on final results, I must take off my hat. If its right. But it skip some logical steps and makes some assumptions in the distance, which I truly believe should be considered a "weak" link.

So, I dont discuss the effect blue has on cannabis growing. But saying that the results of an experiment designed to have equal amounts of blue are due the differences in blue, look as a effect of what psychologists call "focusing". A person is so focused on one topic that see it everywhere, and ends thinking almost anything is related to his obssesion, ignoring any logic in the process.

BTW, somebody on other forum argued that Lydon's result arnt valid neither because of blue contamination of the experiment.

It seem there is somebody obsessed with blue band spreading such things somewhere, and negating any other thing can have effect.

Of course, saying Lydon experiment was contaminated because some body is unable to accept his results is stupid, as it was very well designed, measured with spectroradiometer and lamp and filters used published. But who dont want to see, dont see

i hope i don't come off as rude:hippy:----you need to update/change your translator. i mentally add words that are missing ,change singulars to plural, and add punctuations.still--- when you write something i place a very high value on it and reread it many times as you do know what your talking about :thumbsup:

I don't think knna is a native English speaker.

If anything, going by linguistic similarities in other languages, and given by the pattern of broken English, I'd say he's from either France or Spain.

Wish I could speak Spanish half as well as he speaks English. And I don't think he uses an auto translator. I wish I had taken the time to learn Spanish properly in HS. I do have a second language but it's not nearly as useful as Spanish would be...

My secondary language(s) is Latin/Greek. It made it a little easier to narrow the region knna might be from. And I can tell he's not using a translator - spelling mistakes.

I'm actually leaning more towards Spain/Italy now more than Spain/France.

I belive Spain, as he hangs out at IC Mag in the Spain forum. Plus posts great stuff in the regular section, like lighting. There were some great pictures on the Spain forum, they have a few good LED light builder's over there and some interesting T5 grows/set-ups.

Thank for the support, guys. Im spanish, yes. I write directly in English but I just studied it a bit at school, I learned it by practicing it. Still learning every day, I think my expression of English has strongly improved lately, but I admit I still have a long way to learn.

I usually dont have too much time to post, and usually I write long posts because I like to explain some things, and often I dont have time to check them. Thus many miss spelling, which I almost stopped since I installed an english spell checker. But grammar and phrases coherency still have a large margin of improvement. I do my best with it.

no translator---wow , my problems with reading broken English are nothing compared to the knowledge and insight i gain from your posts----i applaud you sir :clap: and look forward to your future writings.

First off.. I love the BLUE light discussion folks..

All MJ strains react differently to blue light.. It's all about the strains BLUE light sensitivity... What I mean by this is, Some MJ strains when FLOWERED with too much BLUE light will have a higher leaf to calyx ratio then when being FLOWERED under a much more red spectrum.. ie. a 2K HPS bulb.. I have a Blueberry strain and it's very BLUE light sensitive.. Go figure...lol

If your into studding the effect of blue light and you favorite MJ girls.... Might I suggest growing a single plant under 24hrs of BLUE LED light only.. Use any blue led's you would like 420nm,440nm,450nm,460nm,480nm (you get the point)..... OK, I was just joking.... You already no what 24hrs of blue light only dose.... It just keeps your girls vegging... I no what your thinking (no sh*t holmes) tell us something we don't know.

OK THEN...

Now take RED only 630nm OR 660nm led's... Ether one works for this experiment and run a single MJ girl under 24hrs of RED led lighting only (no blue light contamination at all)... Run this for aprox 4 months and come post you results here... I think you will be surprised with the results..

Kanna... This should be right up your alley...
