So when i share data, from what happened in reality, in the past, and someone says “no thats just on paper not in reality”, thats somehow not disassociating the two? Grey and I both caught the same vibe but were just both wrong here?
You are both on the same side of the debate, whether you were both just wrong is a matter of opinion, I guess. I'm not here to pick a fight, I just stated my opinion that what snakedope said and what you say he said, were two different things. That's it.

I understand you liked his posts. However, not a single fact or figure is correct, and he turned to name calling to fend off any further interaction. The single thing outside of this bollox bubble is that hps buds put a smile of my face. Thought that's not making any soft of statement regarding other bud I have smoked. So is an isolated fact worth nothing.

If you want to pick one thing he said, that you are sure about, I will address it. Anything, except that hps weed made me smile.
What was the name-calling? I re-read all three posts, and didn't see it. Anyway. I'll pick one thing for you to address, since you asked me to, and I'm curious to read your answer. Address this quote from snakedope's post- "Cfl has been doing it for years, but with more success in the oils department, as they are usually more then 1500lm at source, they can squeeze a bit more from resin plants"

Ill start here, cannabis is not a “resin plant”, it is categorized as an herbaceous plant although it does produce a resinous material. Heres a list of Resin Plants…

Conifers​

  • cedar
  • fir
  • juniper
  • pine
  • redwood
  • spruce
  • yew
  • larch

Flowering Resinous Plants​

  • mayapple
  • sweetgum
  • creosote bush
  • aspen
  • willow
  • birch
  • alder
  • poison oak and poison ivy
  • horse-chestnut, buckeye
  • gardenia
  • quinine
  • coffee
  • morning glory
  • parsley, dill, fennel, caraway
  • sarsaparilla
  • ginseng
  • rabbitbrush
  • balsam root
  • sunflower
  • tarweed
These are primarily plants that arent primarily vascular material they are woody plants with bark.

Now, how often do you think people have been growing these under cfl bulbs? Lots of production of redwoods and yews under cfl? I dunno man but im gonna look into it.

Edit…..tried researching resin plants under cfl, not finding much but it seemed so clearly not a thing that ill just bail now.

Second Edit - looks like a lot of cfls do not produce 1500+ lm.

How to understand this table – look at the lumens (brightness) in the far left column, then compare how many watts of power each light bulb type requires to produce that level of brightness. The lower the wattage needed, the better.

Lumens (Brightness) Incandescent Watts CFL WattsLED Watts (Viribright)
400 – 50040W8 – 12W6 – 7W
650 – 85060W13 – 18W7 – 10W
1000 – 140075W18 – 22W12 – 13W
1450-1700+ 100W23 – 30W14 – 20W
2700+150W30 – 55W25 – 28W

So, instead of really addressing my quote, you're just going to micro focus on the fact that he said "resin plant" when he clearly meant 'resin-PRODUCING'. It's all part of a kind of arrogant ah vibe I'm getting from your posts, so I think I'll just bail on addressing your posts directly now. Now, THAT'S some name-calling.

So did you miss the chart on cfl lm output? Youre choosing to take it as arrogance when im dissecting the quote and breaking it down. Snake sure posts like he understands the science with the numbers he shares. I was simply fact checking. And i dont care if you no longer address me. How the fuck am I supposed to know he meant “resin producing” when he said “resin plant”. I assumed he meant another category had testing done under cfl he was familiar with. You seem to just be defending someone who multiple people clearly have a hard time understanding. I apologize if my thoroughness was somehow perceived as arrogant. I even mentioned trying to find resin plants produced under cfl, didnt seem to turn up anything. Im very curious what you expected instead of what i did? The only resin related cfl stuff i found seemed to be targeted of course at cannabis and i didnt see anything regarding terpene or cannabinoid production being higher under cfl than anything else. If you challenge me to fact check something, im gonna. One thing you can also call me is thorough, arrogant is your perception and choice to assign to me. Again, very curious how you thought this would go, regardless nothing corroborates snakes babbling. I am truly sorry if I sounded rude, truly not my intention. Im here to learn and show others my experience.

Edit - the “name calling” came from further back in this thread, if you read it all, youll find plenty. Not primarily from snake, but those who are led science and result/reality deniers.

It's really a pain in the ass this thread was hijacked by obscurantists who just say ad nauseum "LED buds not good" and other absurdities. I'm on my second run with my Lumatek LED's the plants are fantastics, now the ambiant temperatures are high enough to have around 23°c with light on.(just the LED no HPS added)
The buds from my first harvest under LED's have been in the jars for a bit more than a month and they are of excellent quality, I think they have a longer shelf life than the buds I've grown under HPS. Those last years I liked better a bud just dried than one stored in a jar for more than a month, I was quickly loosing the pleasant smells and aromas I like so much so I'm happy to see the buds from my last harvest stay appealing to me for a longer time. Even if I rarely have some old buds as I sell most of my crops it's nice to have a product who keep its freshness longer.

I could say the same thing about people who insist that LED's are the best thing in the world for growing weed, period. I mean, this isn't the Let's All Worship LED's thread, is it?

Latest on this topic IMO LED great for veg growth, HPS and MH good for flowering
I got a Mars Hydro 4000 something and it depended on the plant what the results were like

Im going back to a 600HPS to get outdoor looking plants grown
If I do a veg room or a micro seed run def LED

I did use some cree cobs as well

Anyone agree?

It only matters what you like :D. I prefer CMH for veg and a mix LED/CMH in flower.
Loving your work too brother. Ive got two beleaf chimera #2 seedlings going rn they are maybe 18 in tall. Gonna flower them soon. Have you tried or know anything about the #2? That cut youve got looks bonkers.

I got Chimera #4 clone.. I just made a small lot of s1 for the vault. I haven't tried #3 or #2.. All of them look killer.

I have a handful of friends who have been doing some experimenting with this very topic. General consensus after over a years plus worth of efforts combined is that HPS for flowering is still king. I may try augmenting mine with 3000K fluorescent as well on one run, since I have the fixtures setup for vegging already. A simple bulb change will accomplish this for me. I would like the savings that LED's appear to offer over time, but so far, from nearly 20 crops total, unconvinced. My one friend kept his HID stuff, and going to switch back for flowering. May try what I am too.

How about everyone use what they want? 98%+ are using LED. If you wanna stand out use hps or cmh. I personally think most of the weed sucks now because it’s mostly grown under led. I’m talking commercial weed. I’ll do a side by side for myself to see what the fuss is about, but I hate growing indoor anyways, and to add a complicated light into the environment equation seems tedious waste of time to me. It’s only done for money saving and maybe looks. I smoke weed to get baked. I also grow weed and love gardening which is why I hate indoor. I don’t want to be a plumber, hvac, laborer. It’s also impossible to recreate the earths atmosphere perfectly. If I’m growing indoors I’m want a light that just works.

To further explain reality concepts to science people, with LEDs all you did was putting 200 lm in each spot of the space, but that's it, you still have just that, 200 lm per sec everywhere
Very good, you can grow all kinds of things with this amazing low light per sec arrays
Cfl has been doing it for years, but with more success in the oils department, as they are usually more then 1500lm at source, they can squeeze a bit more from resin plants

@Vegg69guerilla got it right with his hps 400, though it might not veg the same like a led array, it's the source strength that counts
A plant doesn't need to be directly underneath a high strength source to know it's there, it can be further away from it, just like we see in nature, some places are closer to the sun some further but we see dank from both places, why ? cuz in both places the source strength is the same, the sun is not different in australia or canada , just how much light each place get is different, weird how reality work...
Anyway, if a 400 hps is like the sun regarding it's source strength, just imagine a 1000w one... We all know what they can do ;)
No wonder people report a stronger smoke with same clones under 400w and under 1000w... It all adds up now.
Except the farther away from the source lightbulb the less light the plant will receive.

OGcrown on IG is running a full room using Growers Choice TSL800. I'll be watching his results with those. Suppose to be a direct 1:1 HID replacement LED. Ive not seen any run those yet. I like the Footprint of those LEDS. These are 800W. Also, the Tarantula Vulcan Borg is another im watching from grandmasterLED, its a beast at 1500w.
