Buds quality LEDs VS HPS

Nutrients and lights are the two biggest factors when determining phenotype expression, grow the same cut under a hps vs cmh vs led you will get drastically different end results.

The only difference is how the light spectrum affects growth. The rest of the environment has as much or more to do with the results.

And I am testing the difference. It's very minor. Seemed major until I learned how to fertilize correctly for the differences.

And how the light spectrum affects growth is fully tested at university of Michigan.

None of these side by sides offer anything but opinion. Too many variables.

I still don't know why people are purists when it comes to HID vs LED.
It's a lot like debating organic vs synthetic.

I grow "semi-organic". 8-)
:peace:
mostly because for years,led guys have tried to sell us on all kinds of claims that are mostly bs. if they didn't make outrageous claims, no one would argue

also, we all grow with chemicals, organics have to be broken down to chemical before the plant can use it

Anecdotally, every old time HPS grower I've introduced to quality LEDs has made the switch or is in transition to LED. This includes serious growers and breeders not just back room growers. All it took was one test run and they made or are making the switch, this is completely anecdotal, lol.
Hey, man, like I said before, anecdotal evidence is very valuable. It just isn't sufficient to make definitive claims, you know? But hell, I switched from HPS to LED and I couldn't be happier about it.

I work in a field where there is constant testing. It never stops. Even after we've implemented, we continue to perform regression testing (for years after the implementation). Anecdotes are basically early-stage data. Part of the bigger picture, and so very useful when viewed as such. But if I were to begin making development decisions on the back of anecdotes, I'd very quickly find myself in a mess. Greengenes' hyper-sensitive overreaction to an honest assessment of the relative value of his evidence makes me wonder if he really understands how scientific testing works. And sure as shit, that attitude of his wouldn't fly in my world.

Exactly!
That's why I don't test drive new vehicles... :P

Him and a few others are the reason why you are even growing with LED you dunce. If there is one thing that his tests and his grow show it's that he is on hell of a gardener. You just got your LED so please just shut the fuck up. Your killing the community. Go back to HPS and go finger yourself on this nice day of Giving and Thanks. Happy gardening friend!!!!

Once again, for the challenged among us - no one was shitting on GG's test. Can you get that through your skull? Apparently not. As for my opinion on GG's character - I call it as I see it. He doesn't get a free pass to behave like an asshole just because he's done shit for the community. There's no excuse for being a short-fused prick. And no, I'm not going anywhere. But keep trying; it's amusing.

That's cool man. But not sure why the focus is on me? My test is what it is and have never claimed otherwise. And have said that multiple times already in this thread...but you choose to ignore that.
All I have continued to ask for is more data points form others. And when I do, all you guys do is complain about me and not give any data back. I'm not at home and am on my phone and will get the few more I have when I get to my hard drives.
So I continue to ask for more data to be given by anyone, specially those so critical of the points we do have. Is it really that hard for people to present anything, just one semi controlled test??
That is where we stand, you can keep making personal insinuations, but I have not denied, turned away, or rejected any data or test present. It's because there hasn't been even one, but am honestly open to look if someone would present it.

Their all chemicals, some "chemicals" have to be broken down to an Inorganic form to be uptaken by the plant...but not always, Amino acids in organic [carbon-based] come to mind for Nitrate uptake...

Organic = carbon based
Inorganic = Not

I havent used the latest led tech. The thousands of dollars Ive spent in the past, on the latest and greatest of the time, heralded as godsend here, and none of them would perform like an old hid did.

I can judge this solely on my Brix readings. LED dis not penetrate and burn like hid. Nutrients were too slowly up taken and too slowly burned, not enough photosynthesis imo. brix is easy peasy with hid because metabolism is faster and more thorough imo fuck led, new commercial growers use hid, or they belly up. led veg's nicely, grow great basil, but leave flowers under hid for best results.

What led lamps did you try?

Organic = carbon based
Inorganic = Not
Phosphorus, nitrogen, potassium, and all trace minerals found in nutrients are carbon based. On the molecular level, N,P, and K in organic soil is identical to N, P, and K in a bottle. There is a very thin line between whats considered organic and what's inorganic. There are no organic compounds that do not contain carbon, but there are carbon containing compounds that are NOT considered organic. Example: CO2, carbonates, and cyanides all contain carbon but are considered inorganic.

Please stop discussing concepts you clearly have no grasp of, like 'organic chemistry'.
This^^
And that goes for anything. If you're not sure, or you lack the knowledge, don't teach others. It's like everyone with a couple grows under their belt thinks they're the next Louis Pasteur. Last week, some guy was on here arguing about seed plants having double the amount of shoots per node as opposed to clones, and another guy arguing that seed plants are superior to clones because they start out with a taproot. Fuckin boneheads.

dont recall the names, pre 2012 I think. some were those 899 square ones, some I think were the 5(watt?light) ones, others a little more or less costs. They vegged great. they did not flower as efficient as my demands required, they all had a (predetermined?) obsolescence it seemed, with entire banks failing within a couple years some times. overall...they might be cool in the game room but none will likely light my rooms again.

I've been about 4 years of white LEDs and COBs after twice that with HPSand CMH. They have been boxed up for years. I tried Lumigrow, Magnum and Vipar blurple And others with unsatisfactory results and used them for veg or supplemental lights. Then I bought a panel with all Cree white LEDs and HID was knocked out of the tent. Only thing lacking was coverage but then I bought a COB light and problem solved. My lights are not even the latest and they all have fans.

Yield is up and and potency is always excellent within particular strain. I run generally 40 watts or so per sq/ft for 10hours a day now. All in all it seems quality is up a bit and buds are always more gooey.

I still have several new CMH Mastercolor and Ushio HPS bulbs.

[sits down in the led anon group..one day at a time]

i started with lighthouse hydro..they vegged ok flowered not ok and had planned obsolescence

I had some cobs made for me in china with crees and fans..still working great

then, when the samson leds started to showup on strips ,

like others who seem to think they invented the idea.. i made a homemade panel from them...they worked good

I drank too much coffee one day ...made an error ,stopped doing it ,forgave myself and

..now i just try to not step on the 7" x 11" design which is popular

but none of the technology was not already out there in some "too expensive" for me commercial lights already
