Does Cannabis Contain Melatonin And Are Our Blue LEDs Using It Up, Causing Problems?

This thread is totally fucking retarded.

Funny to see this after reading your Kessil thread....

I am very interested in this as I seem to have a pretty bad problem with leaves turning on me while flowering also. Recently I've added a DIY panel using mostly warm whites with a few 630 reds and neutral whites. Growth is looking normal so far, we'll see as flowering continues though. I'm starting to think this may be strain related also depending on your spectrum being mostly blue/red. Could having a more Indica dom strain make the blues work in your advantage? Seeing as how in nature Indicas receive more blue light than a tropical Sativa this could hold some value? Just thoughts from reading another thread around here where this discussion was brought up.

Well I guess I should catch up with this thread since it seems to be back from the dead .

I actually started to do the experiment I was talking about. I bolus injected 20cc of Natrol unflavored 1mg vegatarian melatonin mixed with 40cc of water into the root zone of 4 out of 12 Blue Cheese plants in the SoG I was running just before introducing them to veg. I continued adding it during the grow by mixing it in with every feeding/watering. Unfortunately I had some situations spring up during late summer/early fall and one of them was when I went away late last summer, I came back to a broken air conditioner growing an iceberg out of it's refrigeration unit and filling the room with hot air. And as a bonus, my veg cabinet's timer failed and my LED panel and flood lights ran for a few days straight. The air conditioner must of broke an hour after I left because my entire flowering tent went to shit and I even lost my Magic Bud strain . But up until that point I can say that adding melatonin didn't help or hurt as far as I could tell. All my Blue Cheese's during flowering continued to look like shit, with 2 of the 4 test plants looking a little less shit, but I think that's more of a coincidence right now. Maybe it needed pure melatonin or the melatonin needed to be in my mix sooner? A family member even suggested that I need to use melatonin precursors instead of refined melatonin. So there's still some work to be done here.

I am more inclined now to agree with what Trev said about having the right spectrum for the right strain. I'm growing the BC mother out from this summer and it was a much happier plant when I had my T8s running 5000Ks in my 730nm/660nm/630nm dominant flowering tent. It also picked up quite a bit when the Vipar A300 was introduced I noticed. The Vipar has quite a bit of blue in it, but it also packs quite a bit more punch than my other panels, so........

Still, I think you need to pick your blues to work with your reds. Just cause Cree makes some monster blue diode doesn't neccesarily mean you should use it I feel. You don't want your blues to be bleaching your plants when your reds aren't even close enough to be in their sweet spot, right?

^^^unnecessary.

Dank Smoker- You throw those CFL's in there yet? help?
(thinking that may be my weekend project)

Great thread- never settle, always strive to achieve more and stretch the current limits for the next to come and stretch it further.

Seriously? Melatonin in Cannabis? What's next, can smoking melatonin get you high? LMAO ever tried nutmeg? It really does work.

You don't seem to understand the thread Fonz. we are trying to stop the suppression of melatonin not irradicate it.

there is melatonin in everything. all plants plants , animals, people. Melatonin is responsible for hormone growth and stress recovery. by not suppressing it you can possibly have better quality and much bigger yields.

check the links i posted in this thread a while ago. there was even a problem with phillips led tv's suppressing melatonin in people.

just like the t5 thread . you came in bashing the thread then joined in and took over and every one else left.

Fonz maybe there is a lack of melatonin in your system.

we don't need another 50 Spent I mean 50 cent


Its 480nm - 525 nm that suppresses melatonin not just blue genius

if there is melatonin in the pot we smoke maybe it can help replace any lost melatonin in ourselves. just like the same cannibenoids in our brain that deplete if you have alzheimers that are in mj.

it would actually be another benefit for medical mj.


See what I did there DUN DUN DUN



Edit: We don't need no stinkin pills mane

^^^^Awesome explanation^^^^

And delivered correctly.
Thats what this is all about.

Now Brother Scotch You Put Your Left Foot In And Take Your Left Foot Out And Shake It All About You Do The Hokie Pokie And Turn Yourself Around Now That Whats Its All About

lmao oo buddy...I miss the simplicity of childhood..

nothin to worry about except candy and playgrounds

Speaking of which...Im gonna go check Narnia for today!

I have just started to notice cal/mag like spots on my leaves. I supplement with calmag so I know it is not that. My only guess would be the LEDs are to close. Although it is on lower leaves it would be the plant eating itself like said already. Hopefully it won't die completely. Might have to supplement with a cfl or something

i Get calcium problems even at recommended doses sometimes and usually have to up the dosage even more. Also a very good point to give to researchers reading this is that it is very important to also have your 'top up water' going into the res with a calmag dosage. LED are powerful and your plants put a lot of effort to receive high volumes of calmag.

Also, CFL supplements do NOT combat the calcium deficiency but it helps with the yield off course.

So I'm guilty of not reading the entire thread but I read a few posts and the entire OP. If my ideas sound like bullshit they probably are and please excuse them, just throwing in my 2 cents.

Just want to point out that the drop in melatonin levels in humans is controlled by our brain, melatonin is a natural hormone produced by the human body as well as other plants and animals. The melatonin level drops in humans is due to a response from our brain when the blue LED light is absorbed through our eyes.

To assume that blue LED light would reduce melatonin in plants based off only the fact that they reduced melatonin in humans just wouldn't add up on it's own. Plants do not have eyes nor a brain at least not in the sense that humans do. Without the physical attributes that produced the reaction in the human it is like comparing apples to oranges.

Not trying to say this isn't true or wouldn't work. Simply just saying I don't think the basis for the research is enough to actually begin research, at least not for me... But of course each person is passionate about different things. I'd be curious to see if anything comes of this research though.

Forgot to check the page date. /facepalm. And no, she isn't mine, just a very nice specimen of a Blue Widow I found. Its something I'd like to grow one day though. Widow is still in my top 5 after all this time and BB too.
