LED and BUD QUALITY

[JKD]

I wonder if it’s the prevalence of certain genetics now that may display the traits that snakedope is discussing rather than the changing lighting technology.

Would be great to see a side by side using something like Deep Chunk, that has large glandular trichomes.

 

[Crooked8]

^wouldn't take it personally. Snakedope has a weird emotional attachment to his belief that LED can't grow trichomes.

Im not, id love to see his more swollen buds from his HIDs, well see if he posts any.

Like every bro science comment . Waiting for the science .
Two exact same grows . Must be exactly the same . Must use same Clone from one plant for both grows .
Conditions must be exactly the same for soil , environment and nutrients.
I have read actual scientific controlled experiments on far red and uv light . Totally useless and detrimental in large doses .
As for low quality trichrome , hop latent virus is more likely the culprit .
I've grown great tasting super sticky 24 % thc Durban with a cheap blurple and COB floodlights from Walmart.
What's most important is to know what you have and use it properly. No substitute for careful observation. Observe , report one change at a time .
Sorry to preach .

You are 100% accurate regarding UV, they studied UV a b and c nanometer ranges and saw no increase in cannabinoid tests. However, far red has been proven to be really important for penetration along with green lighting. Nothing penetrates the canopy more. The thing about far red is too much will cause photobleaching and some other physical shape issues that are less desirable. And yeah the viroid destroys trichome development along with many other negative things. Im trusting you can tell from the photos i posted we are not dealing with any sort of viroid issues. Our bag appeal is off the charts.

I'll be starting some deep chunk under LED soon, but it'll be my first grow, so I doubt it'll look anything like the pics in this thread, lol

 

[vermontman]

@vermontman

are you using co2!

Mostly no, Though my grow room is in a mostly a closed system within a houshold , so two adults one large dog doing as we do breath which give a large amount of Co2. Except for when it is really cold and I turn on a propane heater, but not added Co2 well above normal levels.
Hope that helps!

Yes beautiful flowers . I believe the trichrome development to be almost completely dependent on genetics. Assuming the grower has skill at growing cannabis. I find huge variation from different seeds same strain . I know LEDs are very different from HID and HPS. How the light is distributed and how heat is created . Completely different. Light fall off different. One must adapt growing conditions dramatically going from HID / HPS . But your saying lower quality , smaller trichromes . That's a first I've heard that . That why I jumped at a different angle . A virus doesn't kill you . They don't kill plants either . But sometimes I look at the finished flowers and I'm passed. My theory. Some plants are asymptomatic, some minor problems, occasional death.
Just read a very well done comparison between hps and COB led. Basically he killed it with both set ups . Top notch flowers . He did thc test . COB grown was stronger.
COB, s are not better . He used that light more effectively.

i don't think it's a good idea to supplement far-red with cannabis. maybe using manufactured fixtures you should add a little but i think these screw-in led bulbs have a significant amount.

i get palpable heat radiating downward from the bulbs at about 6".

this is counter to an upward-moving air flow caused by the fan on top of the fixture.

the cells that sense the red/far red ratio are located on the top surfaces of the fan leaves.

randomly scattered. this is one of the reasons i go after the main stem fans first, from the bottom up as they become occluded.

one of the papers i posted in here somewhere indicated that near uv from about 385 up and the low end of blue stimulated both cannabinoid and terpene production and could possibly be manipulated.

so the blue balance is important.

one thing i thought about today was water quality. that is a huge variable that might be implicated in some displays.

environment and co2 might be something to look at.

also, i'm starting to see that a lot of people on this thread are not growing in hydro like me. we may be seeing completely different reactions to light because of nutrient deficiencies.

i don't get nutrient deficiencies because i'm doing continuous liquid feed.

a lot of variables.

thank you! right now i'm in an old 1940's farmhouse while i'm building a home. it leaks air and has poor insulation. my wife and i and a cat.

i have a digital co2 monitor that i just keep on and it never goes below about 415 ppm.

the reason i asked about co2 was to gauge the possible impact on your yield.

if you had a tight room and were running 1000 ppm it might indicate that co2 was partially responsible.

thanks again!

You literally have no idea what you are talking about. Skinny trichomes that look like not good quality? All trichomes are intact here and look identical with the same strain to when we used HID, also test results have bumped up since converting. The buds glisten like they are coated in broken glass.

Glisten from white hairs with tiny trichome

Its pretty funny to see you try and down talk quality of LEDs when we've had cannabinoid and terpene tests increase.

Fake, I don't believe this BS.

You also deny the science of a man with more federal funding to study cannabis than anyone along with nasa funding.

That's the main reason I don't trust him, he's federal. Do I need to add more ? You trust these people ? How old are you 6 ?

Its pretty hilarious. Feel free to keep growing with parking lot lights,

That's the only stuff you say all the time (all led growers that fell to the hoax), flinston lights ! Old tech ! Parking lot lights ! And not the good parking lots with velet, but the cheap abandoned ones ! Well you convinced me now science man

well keep hitting 75-80 grams per sq foot, with no photobleaching and embarrass you, for a lower cost by far too.

Keep hitting numbers bro, that's all u care about

I wonder if it’s the prevalence of certain genetics now that may display the traits that snakedope is discussing rather than the changing lighting technology.

I'm wondering the same thing to be honest, a friend just came back from amsterdam, he asked all around where the old cheese at, the 2005 version, nowhere to be found, the seller told him kiddos these days want purple no punch mostly, no demend for potent meds,
Anyway it's a very good question indeed, I'm trying to find out for myself lately using some old school strains, well see what happens

Would be great to see a side by side using something like Deep Chunk, that has large glandular trichomes.

I would like to see Chuncky MH grows compared to these LEDs, something tells me I already know who the winner gonna be.

White hairs with tiny trichomes? Are you colorblind? Totally blind? Please show what the actual fuck you mean… Whats your product looking like? If all i cared about was numbers i wouldnt run half of the strains i work with. So you truly think that if someone gets federal funding, that means they themselves are federal? He gets nasa funding too, is he an astronaut? Your arguments are pretty weak man, and again, pretty darn funny.

I use IR supplementation, with incandescent lamps. The general service lamps that cost almost nothing.

They were terrible for light, because they are heaters really.

They only serve to promote elongation, for me. Which I rarely need. I think the red balance response needs some near IR as a subject for the plant to study, as it were. The idea came before the trial. Which has led to the incandescent lamp being part of my tool box.

I'm not sure this has any effect on the product, except through shaping them up. Leading to better health.

Color blind ? What that has to do with the size of your all neck no head trichomes bro ? Get serious please

No, that means his a liar, like all gov agencies and universities that get funding from the gov, all caught lying 99% of the time, so you think now they will start to tell the truth about something.. wow naive you are.
All funded research will get the results THEY want, no matter if it's true or false.

He gets nasa funding too, is he an astronaut? Your arguments are pretty weak man, and again, pretty darn funny.

Your gov and nasa arguments are weak, no real science behind your words, just titles, nasa this and prof that, all BS. Nasa is the most lying bunch on the face of this earth,
NASA - Never A Straight Answer organization.

Keep believing those fools, just shows that real life research and truth has nothing to do with your ramblings.

Buddies (String LEDs) - Grow Lights Australia

"Buddies" grow LEDs fill the gaps other LEDs can’t reach. Tough, waterproof side-lighting, under-canopy lighting, supplementary Far Red and more.

check this out! they are using a 4000k white with accessory red at 660.

mars hydro uses 3000k and 5000k, which together are close to 4000k but the 3000k has a little more far red and the 5000k has a little more blue and some uv.

check the "grow buddies".

i think snakedope needs to go over to truth social! he will find friends with like beliefs there.

i think general purpose ignore is the right tool at this point! it's almost beyond comprehension.

apparently, there is some magic force no one else has ever heard of in those hps lamps.

i must have missed it in 22 years of hps use!

BOTH IF YOU are acting like a couple of girls!! Just block him if you're that worried about his replays. If you haven't grown killer cannabis in 22 yrs with Hps then you'd better hang it up pal. LEDs won't help the matter. Jesus man let's all just get along here

i'm not worried at all! in fact, i'm having a good time. his stubbornness is world-class.

if it were an Olympic event he would most definitely get gold.

and why do you think i haven't grown dank with hps in 22 years?

please respond to this question!

and i am editing to add this.

"LEDs won't help the matter", so here you are admitting that you are one of the anti-led group.

again, i will point out that the thread title is "LEDS and bud quality".

not "ditch leds and go to hps"

or " leds are shit, you need to go back to hps"

or, "the sun is best"

if you are not sincerely interested in improving your own led grows then you are an impediment on this thread.

once or twice is ok, you make your point and we get it.

but for someone to try to continuously and repeatedly interrupt and bash those who are sincere is trolling.

i am not a mod but if it keeps up i will do everything in my power to bring a mod in here.

maybe they are aware already, i don't know.

icmag was the greatest single source of information online for many years and we had a lot of great growers on here.

i learned a bunch here and am still learning today.

i took a little hiatus from the mag for 3 years while i worked at the 10k sq ft hemp flower facility that i designed the following for; 800 amp service, all electrical and plumbing maps for a completely automated,
closed loop, recirculating, hydroponic system that i also am the inventor of.

and, when i got back to the mag last year i was, honestly, shocked at the trolling that is going on here now.

it is damaging the prestige and reputation of one of the great, historic cannabis sites.

i actually care about this place, and i think it's time to take out the trash!

here's a link to what i do. this was my last effort with hps lamps. i used the best available at the time.

Something wicked this way comes

this thread is intended to show the "state of the art" ppk plumbing. since i started on this journey more than seven years ago the basic operating principles have remained the same but we have all gone through many iterations of plumbing. most of these, i now realize, were derived from our...

sunlight supply ac/de's with philips green power lamps.

the facility ran on a schedule with some of the dankest strains i could find in the states of oregon and california. i personally selected the best proven cuts i could find.

i used COA's there because the law required it. these COA's said that i was growing high % thc and that it was terpene heavy.

from all this you might extrapolate that i maybe, just maybe, might know what a quality fucking marijuana flower looks like, smells like, and tastes like.

and now, for the last four years, i have been growing with leds and i know that i am producing very nice flowers.

you may not think i know what i'm doing but a lot of other people do.

i have a professional reputation for producing quality, do you?

so, please, fucking pretty please with sugar on it, if you don't like leds why don't you ignore the entire fucking thread instead of telling me to ignore an idiot. or two.

@Crooked8, hey buddy, so obviously, you are associated with a group of growers because you use the term "we".

you sound professional, which is where i am in the cannabis world. you must be career oriented. do you guys use COA's?
