LED and BUD QUALITY

I think i better hang in here for a while, for great quality bud sake :p

Hello Snakedope. I study future agriculture concepts intensively. Led has not avoided my radar. I've quantified the physiological differences under LED. I often wonder how to divulge such valuable knowledge. I will say it like this:

When a lot of the big NorCal black market kingpins went legal, they had to stop stealing water. The legal water source cut the size and quality of their plants significantly. Not a single one of these legacy guys could figure it out. We saw guys using peat moss with zero buffer to get any trace of flavor, and accepting 25% reduction in weight...

Then the dep and indoor ops started switching to Led since they couldn't steal diesel anymore. They did this before learning anything about light or plants or the photosynthesis that connects them. Marketing, technobabble and impulse always come first with Cannabis folks, sadly. Now under led, quality was too low to hide and yields were too low to profit off extraction. Lots of these guys sitting on permits right now, because their product wouldn't sell.

*Skipping the boring scientific details*

Long story short: Under hampered DNA expression caused by congenital nutritive issues, Led spectrum forces CaCO3 in the plant to create cyanidin glucosides and re-solublizing calcium carbonate cystolith structures as photo-oxidative defenses, and lends itself to fatty acid conjugation and creation of calcium soaps. Typically, for thousands of years, cannabis created thiols, not anthocyanins and calcium structures, to protect itself from UV. This is a major turning point in the evolution of a plant who's photo protectant properties had only coincidentally drawn our interest thousands of years ago. We've all seen cannabis that was "all neck, no head". I'm old enough to remember Cannabis with zero necks whatsoever.

We've all made a vinegar volcano in school. What neutralizes the acid in a vinegar volcanoe? Acetic acid is neutralized by solute carbonate.. Acetic acid, specifically, is the reason OG Kush is special. Pinene to pinyl acetate. Borneol to bornyl acetate, limonene to limonyl acetate, linalyl acetate etc. All strains rely on carboxylic acids. It's where the cannabinoids and aromas of Cannabis originate. All carboxylic acids are neutralized by carbonates.

The aromas from the region trends right along with the push of lime based calcium. Skunk (thiol) vanished. Babyshit (calcium soap) came and went. Now it's baked goods, plastics, shoe spray, cold metal, cream, vanilla, butter, synthetic chocolate, candy cigarettes, chalk, milk, cereal milk, milk and cereal breakfast bars.. Breeders, with the power of evolution in their hands, took the shit out of the Babyshit, which was an era of mids to begin with. The era today is the Babyweed era. Devolved Cannabis in the hands of the west. Grown poorly for dozens cycles, finally killed under Led, the dro that broke the camels sack. No wonder tissue culture is so hot. It used to be all funk, no baby. Now all baby no funk. No thiols. Babyweed. People are hyped to catch a whiff of a lemon peel these days... And it'll be over a Pepto bismal background when they do, or perhaps sprayed from a bottle. Market data confirms people will smoke anything today, any form of incomplete metabolism EXCEPT green leaf volatiles (hay) and amino catabolism (fishy) .



The solution is to run a wider calcium:boron ratio and eliminate carbonates completely, on top of proper nutrition (which includes microbial metabolites). And to make sure every enzyme cofactor is present in the soil. There goes all the infertility issues the boron deficient breeding experts seem to have.

Can you judge these issues remotely?

Yes

Plants affected by excess Calcium carbonate will have burnt tips, bumpy course leaves, light sensitivity, leaf drop, purple stripes, curled midribs. Botched smells. No euphoria. No therapy. I can listen to a trimmer handle a cola and hear if it is affected. I can look at the cloud you blow and tell by the smoke texture. I can tell by the look on your face after taking a dab. Modern concentrate is what, 90% thc. What's the other 10%? Calcium conjugates? Smells like it.. Tastes like it. Feels like I should be able to sue someone after ingesting this:

Domestic quality standards have changed drastically since growers in Norcal are no longer stealing their fertilizers, and are now attempting to make their own with the help of snake oil podcasters posing as communal consultants, or some other various "community" of salesmen and saboteurs. The "organic" cannabis podcasts are the absolute worst.

If you are trying to do the earth good and join the organic movement, whatever you do, ignore the people telling you to put carbonate in your coots mix, or anything that sounds like it comes from that realm. We have always and will always buffer peat with basic slag, calcium silicate. Craft growers worth their salt will be avoiding calcium carbonate at all costs, not recommending it to be top dressed onto flowering plants. Cannabis hates CaCO3 and anything produced from it (calnit), you can tell by looking at any grow journal.

No this problem doesn't only affect Cannabis grown under Led. Cannabis grown under led simply hyper accumulates this problem, it's growers hyper ignore it, and the breeders have no awareness that they continually neuter stunt and cull their best plants.


I've performed graduated experiments. Known cuts will change aroma on a day by day, to week by week basis as you feed them carbonate. When the aroma changes, it is degrading: we have identified aromas associated with lower quality, taking most subjectivity out of the discussion around judging quality. 99% of people's opinions no longer matter, the science is inarguable. Chalk flavored weed is low quality. If you like it, that's okay. It's okay to like low quality. I prefer low quality women personally. There's nothing wrong with liking a 'strain' that smells like a pair of new shoes, but that's objectively the result of poor quality Cannabis with incomplete, altered metabolism.

smartpot-jun10-orig (1).jpg


Every time you see a fabric pot in the hands of a Cannabis grower it has limestone deposits leaking through the bag.. And the laundry list of lime injury symptoms typically mis attributed to nitrogen tox by ill informed growers. I don't even need to see the leaves in this case to know the buds will suffer from the hand of hardwater, powdered cow bones, homemade calcium extracts . There's a reason nature dissolves the entire animal quickly, except the bone.. slow release only. There's a reason various cultures dating back hundreds to thousands of years employeed various means of restricting transpirative flow before harvest in regions of high alkalinity.

The frostiest, least potent bud I've ever had in my hands, professionally grown by a well respected producer in southern Oregon, was absolutely loaded with calcium conjugates, and completely unsmokable on taste alone, as it tasted just like the bone meal poured in the pot. Forcing myself to consume it, I was left with total regret. Like being in an Oscar Meyer dumpster fire, but less exciting by far. . I do have scientific review on how the calcium in the bone meal drags fragments of carbon and dna from the cow into the plants structure, but you can try it for yourself if you don't believe it: 2 cups of Sta-green bone meal in a 15 gallon pot of dank organic bud, mid flower. Take cuts, make seeds. Youll see. The offspring is ruined. You'll realize all this industries problems, instantly.



Tldr: Cannabis growers have historically failed to diagnose excess CaCO3. LED spectrum forces the plant to utilize a larger portion of Calcium in defensive manners which are completely unuseful to Cannabis consumers.

Instead of learning to steer away from the possible permanent, irreversible destruction of an already threatened gene pool, the standards for cannabis simply are changed by the ones producing it, as in the past (when simultaneously the seed industry began and seedless weed became mandatory). Purple is no longer grouped in with brown as it should be. (I challenge growers to produce a plant with zero "royal brown").

People growing increasingly shitty weed under Hid were unable to satisfy their own low standards after switching to tap water and Led, which turned their plants into limestone statues full of calcium soaps.

Good growers under Hid noticed a decline in quality under Led and addressed the issue using science and logic.

Average growers typically dont care about quality, and really never notice anything about anything until they are told to; the most untapped data resource on planet. If you could get the average person to simply hold observations and be honest about them, we'd be on Mars by now with all the data that could be collected. It's extremists who lead us down winding paths instead of presenting their piece of the puzzle. The extremists in society are always on the stage, but never have time to present anything meaningful. They repeat themselves while on the clock. The average person simply feels his voice holds no value in the presence of the loud, monetized extremist.

Throw your dolomite away, return your TM7, ignore the guy trying to scoop rocks out of his back yard and sell it to you by the bucket. Buy a pallet of basic slag. Use normal fertilizer. No calmag. If you need calcium, you're short on boron, not calcium, so add boron, you'll get the calcium. Ignore the old guy who whines about 'millenials with ph meters' while telling you to dump 4 cups of random chalky minerals into a cubic foot of balanced soil. No one wants to smoke his herb. I've tested his special soil mix. Trust me!

Put science into action!
Once you’ve read the plethora of fantastic information provided in this thread, take samples of differing plants, flower them in differing environments that fall within min/max parameters of cannabis growing, then do QC until you find what you like most.
Voila, deductive reasoning and science, the basis of genius….

It's def not a perseption. None of us want LED to fail lol. Skunkva and JLoud are some of the most experienced well know growers there is. I've been doing it for 5 decades. We all want LED to work the same as CMH/HPS does. For us, it has not worked for breeding purposes. Using HPS/CMH for the same breeding purpose has never caused any issues for us. All of my tests using LED as the light source on reversed plants did not produce the same results for plants under CMH/HPS. None under LED were usable as a pollen source. As I said it's a known issue making FEM pollen using LED. THE BIGGEST ISSUE I SEE FROM OTHERS IS THE REFUSAL TO ACCEPT OTHERS RESULTS/OPINIONS.
Until everyone gets on the same page people will continue with the same BS.

Definitely an interesting fact I didn't know, as I don't breed. I think the original focus was more on bud quality itself, and I have definitely seen some good LED bud. What's your opinion on that?

I wonder why specifically pollen/males struggle when it seems the female flowers develop normally- either into good bud, and can develop seeds normally (at least in my limited experience). Little experience with males so I'll take your word in this one

oh no not that guy again now too.... every facking thread in any grow-forum worldwide about light or plant nutrition is being invaded, and taken hostage, by an international operating tinfoil hat crew telling you the same old story over and over and over again :/

"GrodanLightFoot" "GhostofSubcool" "YellowCannaryConsulting" .... but you had an account here last months, I've seen it the same pics with your Bor-def plant that wasn't even cannabis.

I mean I don't want to come of as rude really it's obvious you put some effort into this but then when people ask about if you can show plants grown in your soilmix, or a proof you're actually a grower like a report, there is never any response. Same is for you @snakedope.

It could just be much more integer and credible if it was presented differently. I mean heck, yeah the kings of the underworld can't figure out how to get an RO unit running or throw a handful of calcitic at a sack of peat! it actually comes buffered already with that or you wanna grow at pH 4.5 lmao!!!
How about you

The lights never entered as the cause when I 1st encountered the issue. I thought the Chems had gone bad or I did something wrong. I even tried a few more with new STS chems and still got the same results. I never had problems like that unit l started using LED. I started searching for this prob and found others having the same problem. I asked about it, they also had poor results. They said they switched back to using HPS/CMH to make their pollen and it fixed it for them. It was causing a lot of delays in getting projects started for me. Swapping back was pretty much a no brainer.

it may be fruitful with LED in the context of spectral composition to name the lamp because these could theoretically have any kind of SPDs so there's that. A blurple is way different than a white light. Most fullspecs are nowhere near as full as MH/CMH and a 1 diode fixture won't be able to have sufficient farred or UV on board, yet there are photoreceptors that see these wavelengths.
Phytochrome absorbs well over 760nm and cryptochromes/phototropins/UVR8 way into UV, even UVC

Wow, thats all i have to say, when i saw that fabric pot i got a flashback of my LED grow lol
I thought it was mold at first, but the tent was so dry (30-40%) that it seem not plausible..
Thanks for clearing up what i kinda know, the value in your post is immaculate !

Cerathule, i do believe the spectrum of led is superior, but for me, i find it a very bad source of light
Walking down the street and looking at those new led street light, i nearly went blind...
These lights are not good for us, not for our DNA and not for our eyes, not for your skin, its just not good.
Everytime i put the led panel too close at lets say 70-80% power, the plants start to die, like something is wrong... but the temps are good, rh is good, water is good, so what can be the cause ?
I triple the height and dim to around 50%, now everything starts to go along... why is that ?
Novice growers will tell you again, Too much light... so how come i can put my 600w HIDs at 5 inch from my plants and no Too much light symptoms happen ?
I think its because this light is just bad, up close it kills, from some distance plants can utilize it, humans still suffer from it even from distance (try looking at that street light for more then 5 sec)

Yellowcanary gave me a whole new perspective on the matter, my theory was that LED is limited to a very low count of LM or PPFD, thats why its having a hard time giving me glue and hammerhead pollen...

And here you are putting down led lights while it was your grow that was messed up all along! That's not a good basis for the scientific argument you pretend to be making the whole time, amigo.
If your plants looked something like that, moldy & fucked up proper - then the problem is with the grower not the led light. I can assure you.

It’s the radiant heat-quality of the led’s photons that are dehydrating the plant tissue. You just have to find the right hanging height for your leds to make them work.

Hydro/coco growers can keep their leds closer to their plants than soil growers cause in hydro/oco plants ther’s more water in the plant-tissue, so they won’t dehydrate/yellow so easily.

Bro you need to stop taking things too personal lol
My plants is always killer, only under LED i suffered issues thats why im here .....
YellowCanary gave me good insights, its a host of things that LED causes, not just the lack of intensity.
I never had pots like that before LED, weird to say the least

And if it was my problem only then i wouldn't rattle about it, as its my mistakes
But the truth is that its a problem all across LED growers, not just me.
I always grow HIDs, i tried to believe in LED also, bunk

quality of led photons... ? i dont follow on this.
LED is just better at making electric current into PAR, having much more types of waves, but the source and how it achieve this is not good for plants or humans,
Your explanation about plant tissue might be truth, although i dont see it with HID radiant heat which is a lot more then LED...
Something just dont add up to me about this, Yellowcanary is on point indeed with his research, may more opinions and growers share their knowledge with us.

Have you tried different PPFD/DLI levels? And are you and your colleagues using the same spectrum/equipment? Some people get a full spectrum LED light that has lots of blue or a flowering spectrum that's weighted more red. What you're stating is a fascinating issue, though I'm sure you think it sucks balls, but you're onto something and IMHO it's spectra related though as GC is pointing out it could be light stress/heat stress too.

It’s the radiant heat-quality of the led’s photons that are dehydrating the plant tissue. You just have to find the right hanging height for your leds to make them work.

See this all day long in my tent. I'm trying to use predigested organic ferts and water soluble nutes but sometimes I just can't keep up with the plants growth and needs in soil and have to really back off the lights. Maybe the organic crew has a mix that can used. Truth is though I am off my game after not growing for 6 or 7 years so it could just be me but I'm definitely thinking of switching to coco coir but even with my lack of experience compared to others I can tell soil just can't keep up at certain levels.

photons act as heat-carriers and leds create condensed beams which then create hotspots on the plants heating the tissue up and dehydrating it. HPS/MH light is much “softer” and you don’t have such condensed beams with their light

I think it has to do with moisture levels in the plant tissue, not nutrients, and so coco/hydro plants don’t dehydrate as easily as soil plants cause there’s alot more water in their tissues. I’ve grown my G13Hz keeper side by side in coco and soil with the same nutes and the only issue seems to be that the soil plant’s tissue dries out easier.

With soil plants you just have to have abit more distance to the leds/ turn your led power down abit compared to hydro/coco plants

Fluid movement in soil is slower than in coco or hydro. Giving plants a better chance of surviving in low RH conditions. These conditions cause a closing of the stomata, but as we drop below 40% most are actually loosing control. Add to this the water demands of a higher rate of photosynthesis and leaf droop is a reported outcome.

Your room is 20-30% RH and you speak of water retention problems more than anything else.

Your room is 20-30% RH and you speak of water retention problems more than anything else.

You have seen the plants do better in the 30% months.

You blame the lights for heating the plants. However, that is the very last thing they are going to do. No light is colder. They are dry because it's dry.


Experts have recently been picking apart survey results. The low RH group only do so for rot protection in the last few weeks. With 40-55% RH being targeted. They don't grow at that though, it's just the final weeks of bloom. That is the low RH compromise between good plants and rot. Below 40% is extreme and damaging. I wouldn't even bother myself. I know they droop under any lighting if I run such numbers.

Redrum 92 - i will address you as other just busy speculating and judging who and what i am before they even know me and my history, sorry i dont roll with that.

Its not about believing bro, its not god haha, the reality of the situation is that we had killer weed for many many years, and in the last 2-3 years the quality has gone so downhill its making me wanna smoke tobacco more then weed, can you explain why ?

Now if you think that all those people that grew killer shit for years and now all of these people suddenly forgot what they are doing is naive at best, you need to look more clearly about reality.
I searched for a long time what the hell went wrong, and i found the blame, L.E.D !
Dont believe me ? its fine, im addressing the OP, explaining why his HPS bud was great and LEDs bud is "aromatic and nice" lol :p
Saying that you all grow 20+ years, and still dont understand is even more perplexing to me :|
After seeing Curtis grows, Delta, and Wall, im safe in my explanation why this phenomena is happening, they are not different from other LED grows i see, in fact, LED grows so much similar traits (like under developed trichomes) that its so easy to tell LED and HPS bud.

Wall - "scientists and cannabis are 2 different things...you are not a scientist yourself, and not yet an experienced grower." haha thanks bro for clearing that up, you know me over 35 years so you gotta know what i am and what you talking about when it comes to me right ? sigh, you make me tired with you personal stuff, talk about matter of the stuff, BUD QUALITY UNDER LED, i am not the issue here.

I dont understand what you contribute here beside that.

How is HPS\MH light is more softer ? the beam is present in HPS\MH lights also, and is more powerful then LED

I left my rooted clones under a 650w panel, at 8 inch height, everything was good, then the AC stopped working for the day, when i came back temp was 34C under the LED, so i got away with it, if it was HID they were toast.
Still not following your logic, HIDs have much more heat photons then any other light and still you dont get the symptoms of led in the same height under HIDs....
So please try to come up with a better explanation for shitty LED tech, this one just dont cut it, for me.
Something else is happening, plants dont like these lights, only when its dim and far they respond ok to it.
Hammerhead is having troubles with pollen, i have problem with glue, people here are raising true concerns about this TECH and what its able to produce,
But people here still try prove that this tech is good and we are stupid or some haha
Like i said, for every bad thing led does, someone is gonna jump and excuse it somehow, and that excuse will always be the grower fault, not the lights, this has to change.
95% of people get shitty results, most of them are very hardcore growers with many years of dank under their belt, but now, they are too biased or too invested in the LED game to ever consider the topics we are trying to convey.

People might respond less negatively to your observations if you said that you have found HPS to produce more aromatic flowers (or whatever you mean by "GLUE") instead of saying that YOU ARE ALL GROWING HORSE SHIT!!!
