LED and BUD QUALITY

[greyfader]

trichomes do not explode because of internal pressure because the cell walls are flexible and are designed to expand as they grow.

they do rupture because of external contact with something,

i use the "minimal handling" approach on my flowers. i hand-pick bud leaves and use scissors only to cut the flowers off of the branches.

i have owned several metal-bladed trimming machines and a large Tom's tumble trimmer that uses a nylon net. they all tear trich heads off the stalks.

i have never seen a cannabis plant grow just trichome stalks.

several folks in this thread have expressed the idea that the lighting somehow controls or can influence trichome size. this may be slightly true within the confines of a single genetic but, overall, trichome size is dictated by genetics.

This is truth, thank you GF

the above are just a few of the flowers i've grown using the walmart bulbs you so disdain.

Gtfo dude that's what I got to say to you, I took a sample bud 1 week ago from that high temp lame ass grow as you claim last week and smoked it today and let me tell you it wasn't full dry but It was better tasting and smelling then all your led weed combined

Bla bla bla, tell that to all the supreme ganja growing in morocco and India and australia at temps beyond 35c, oh wait, don't tell them, they will laugh at you and you will cry like you do here

I think u are just an old pot head that has no relation to reality, a sensitive pot head, their the worst.

Lol I don't need convincing to use them, I know they suck bro but keep dialing them in, you'll get it eventually.

No, this is a bud quality under led thread lamer, learn how to read.

Just my 2c here but imagine if you took those moroccan, indian and australian materials and you brought them indoors. A completely controlled environment with co2 enrichment, higher DLI than the sun can provide and more ideal temperatures? Lets also remove any risk of pest or fungal pressure and the resulting quality reduction. I 100% guarantee you would improve the quality of the product indoors and see genetic potential you truly cannot produce in the wild. This is why indoor production fascinates me to no end. Not hating on outdoor either let me be clear, some of my favorite smoke of my life came from outside.

 

[Crooked8]

They look awesome, do they smoke like they look ? I doubt it.

Why wouldnt they smoke as good as they look? Those buds look fire.

Trichomes all intact, clearly seeing amber on them on budsites not just leaf material.

He, like i did, showed you material with anthocyanin production as well as solely green buds.

His buds have good morphology/shape.

These were all things you pointed out to me as critical issues that leds cause and you did so without proof. Now, youve had multiple people show you their product with nice shape, trichome maturity and structural integrity(not headless trichomes).

What factors are coming into play that make you doubt their potency now? You even used the term “where theres smoke theres fire” previously. Which is basically another way of saying if something looks the part it probably is. Which i agree with. And those buds look great.

 

[Crooked8]

Anyway, heres the ladies at 13 days in, filling in nicely. Ill throw up a second trellis in a day or two. Happy gals under the bars stacking tight. They will get a decent dryback here soon as well to reduce stretch at this point.

Please calm down and be ontopic from now on! We had to ban one member, and we will watch this thread for any more problems.
Thank you!

Indeed, like I told him they do look great and awesome, I just don't think they smoke the same, my experience, not proof.

Again your and delta buds look amazing they really do, but so does a lot of other led growers, but you smoke them and their not as they look, that's all I'm saying
I'm not pointing any heat or beef at your grows or buds I just think any led bud is shit, don't take it personal.
If any led bud would be good I would have smoked some by now, but more then 4 years and nothing... And believe me I smoked so much I consider quitting cuz it's just not worth it anymore, they destroyed the weed game.
Again, I agree genetics us probably responsible for 90% of the expressions we see in plants, but LEDs just make them go in another direction in terms of the processes that goes in the trichome, if it's size, active compounds, terepene profile, etc
And again, don't take it personally, that's my experience with them and the buds grown under them

 

[greyfader]

ok, you've made your point! many times, over and over again. everyone gets that you don't like leds.

so, isn't it time for you to move along to another thread since you have no interest in leds other than bashing them?

To be honest, i was sceptical too about led spectrum, bud density, thc content. But after spending several months analysing what the spectrum actually is and how plants react to it I understood that LED is the deal, where you can adjust every colour/spectrum by your needs (or lets say for specific plant variety/-ies).
IR / UV lights can be added separately (to maximise thc production).
Tried it by myself and was amazed, cheapest one could find on amazon and was amazed how frosty plants become only on week 3. Never seen this with hps lights. And that is cheapest led diodes which are old generation and etc..
So there is no need to cry about thc levels drop, unless you make 1:1 (led:hps) grow test and after send buds to lab for detailed test for thc/cbn/cbg etc. together with terpene profile and make this "rumours" come to end. If I would have possibilities to make it, would do it right away.

HPS lights produce tons of green spectrum, which is irrelevant for plants. Thats a fact.
Leds produce the colour wavelengts which is designed for.
Some of diodes produce specific spectrum for example 620-625nm, others go deep red 650nm. And they do not produce waste spectrum which consume energy and produce unnesecery heat. They are designed like this.
Other type of led are more broad spectrum, they produce nice yellow / blueish lamp and are intended for daily light for hoomans.
Those will have a bit of green spectrum, because light colour comes from red green blue mixture.
So to get yellow lamp we need a bit of green, but very minimal amounts.
In grow led diodes this is minimised as far as I checked brigdelux, samsung and dozen of other diode datasheet. (not specifically for growing, but still has much lower amounts of green light in them).
So only looking at at elimination of wrong spectrums led lights are at least 30% more efficient.
Looking at new samsung 301b/h and even next gen diodes which can push >160lm/w I can really say - HPS times will come to end, unless you enjoy spending hundreds of $ for AC and waste spectrums.

Example: https://led.samsung.com/lighting/mid-power-leds/3030-leds/lm301b-evo/
Luminous Efficacy: 230 lm/W
Even they are lacking a bit of 620->625nm reds, making led light they can be easily added. And that is the point and biggest advantage of led lights.

Biggest disadvantage of LED is dependence on temperature. The hotter led is running, the less efficiency it has. And with more temperature - colours starts to shift, it means i can become not what you want to get.
So buying cheap led lights without heatsinks and active cooling fans is the problem.
Don't do it. Spend 100$ extra, but buy a quallity thing from brands which understands what they are doing.
And let your plants and wallet breathe more easily.
Cheers icmag community.

Also spectrum analysis.

For reference, this is under CMH.. It is the only difference in my plants. All get the same feed. I can't get plants to stay this green under LED so far. Im def not giving up, ill figure it out.

Green light is not “irrelevant” that is a common misconception and has been debunked.



Green light is very important thats why it is included in Leds.

In addition, IR and UV wavelengths UVA, UVB and UVC have all be studied at length and have no correlation with increased cannabinoids or terpenes. That is also a myth that has been debunked.

As far as Led vs HID chamber test results it was found that there were higher overall cannabinoids and terpenes under leds. They put out more photons and since they dont radiate as much heat, monoterpenes dont volatilize as much so they stay in the material where under hps they would literally disappear.

Not hating just want the truth out there. Peace

Maybe it is important for some parts of plant, will not get in the details as my knowledge is old and outdated. But from what I see, dominance is blue with red. Same like in grow led lights, which get supported by 2500k-3000k additional "yellow" leds which are the ones to have broad spectrum including green. Maybe this is even a case, why plants looks different (i noticed it also, but blamed low grade soil which i mixed together with good one).
But what I wanted to say is that HPS overproduse the spectrum which is not beneficial for final taste/size of the product where with LEDs you can precisely control it and make a absolutely perfect grow light for plants without wasting a watt of energy. But scientist must research it and understand it fully, then it will be a happy days !
Peace!

You can only control spectrum with LEDs, not intensity.
Spectrum is old dated research, it has almost no impact on whather your bud is good or bad, ask every smoker or grower in the last 50 years they grow under HIDs, they will tell you

 

[FletchF.Fletch]

Not alot of new companies entering the HID market. Therein lies the problem. Finding reliable equipment will be next to impossble in no time. You can log a few more grows under bulbs before they stop making anything but counterfeits, but LED is the way the Tide has turned.

You literally control their intensity all you want. Potentiometers/dimmers make this very easy.
