I ask because I really don't know. I would assume that two 500's would be better? Theoretically.
Best light on the market ?

Ya hes a little out-there but hes also pretty close to being right a fair chunk of the time.
I agree with him that plants use all the light for reasons known and unknown.

More total weight from the 2x 500s, bigger and stronger buds under the single 1000 from my experiance. Except it was 2x 600s vs a 1000

I ask because I was wondering if you kept splitting the 1000w in halves, 2x 500's, 4x 250's, 5x 200's, etc., etc. wouldn't you basically be getting down to a led like cobs, or quantum boards? If they were full spectrum, and if they were hypothetically the same draw from the wall.
I really don't know, just asking.

You must be 3 days older than water,as hps lights have been readily available since the the 70s,I’ve been growing for almost 30yrs and always used h.i.d lighting.

Thats just a primer so you can appreciate spectral lines and what it means.
Its a lot more complex than that simple example but we can futher sub divide each colour and effect on photosynthesis.
Its a chance to learn, im nit a teacher though

Great question, i tried to make threads on this a while back but to compare say a led to t5 bexause hps dont do small wattage in grow lights or high power i think.
So take a 24watt true draw qb and a 24watt t5 and see if you can see between 15% - 50% extra growth.
We can sumise a lot of tests with leds.
As to hps 600w is the most efficient i think over 250/400/1000watters.
Personally i found those who switched to leds in other hobbies have turned back to t5's as they have the best spectrum and efficiency combined.
Theres a lot to learn on phosphor, ever wondered why some aquarium t5s are five times the price of your office fittings? Because the phosphors which come very close to the spectrum of the sun cost more.
I know more about light than just led vs hps, these led mofos just been humping ppfd and not learnt the rest

I once had a 150hps.

How do you figure green is absorbed the most? No botany class I've been to has stated this. Its why leaves are green because it reflects most of that spectrum. However it is still used in small amounts.Plants use all photons, because of the shade effect lower leaves absorb green the most.
Please lets not paste more redundant info, light is photons and no photons are refused if receptor sites are free.
PPFD states that if you use 30 green 30 blue and 30 red you will out grow 45 red and 45 blue, thus the sum of the parts are less than the combined.
Now we really start to get into ppfd and light, not like leds did with

If i can come back to your question and say that -
I didnt do the thread or the maths and science but some clever ass mofo worked out here that if youwere to make an led grow light with the exact spectrum as a hps (including spectral line data) you would reduce efficiency to about that of a hps.
Now that science and maths is beyond me but i too believe that led efgiciency is sold under a fakse impression, they have to stay within certain confines or they badly loose efficiency - why there all such.low wattage as higher wattage leds get worse than hps efficiency.
I talk discuss and give actual points, dont be fooled by led idiots, the real growers know how to run any light and have no issue with heat ever.

Zoom in on a leaf dude, is it all green or are there gaps in the Chlorophyll?
Am at a very high level because this site forced me, no arhument you bring up a good point i hope you agree with my answer but there is more to the story of gree light lower down in the canopy.
Highly studied sciences, i merely give the answer science gives mot my opinion

You just talk to hear yourself talk. All bullshit info going in circlesPlants use all photons, because of the shade effect lower leaves absorb green the most.

Well for me I never liked the results from less than 1000 watts. I prefer the way my buds come out from a 1000 vs a 250, 400, or 600. Everyone has differant goals though and what they prefer can be differant than what I prefer.
I've said before an I'll say again my best buds have come from a combo of led and hps.

I say shit you could verify on wiley or google or ncbi with enough time and an educated background.
Saying i talk shit dosent negate all my referenced to actual science.
That crap about red blue and green light ppfd yeild has been well known here but like i say to newer members 'be open minded dont just troll an opinion as you wont learn dick'.
Did you just comecherecto be an ass or part of a knowledgefull site cause your shooting down stuff that has always been 100% fact until you and your egotistical kind came here to try and rule us or somthing.
Im not that grower, im a comtributor, i give validity up and above your broscoence. You say get leds if its hot whereas i say learn to deal with heat and run any light then explain heat in 100% accuracy.
Your looking like frauds, you didnt discuss ppfd you just humped growmau and leds and your ego

I'm sorry but this dudes a fukin idiot. I have a 6 cob 320 watt cob setup that absolutely murders my 8 bulb 400 watt t5. This is not bro science.i dont need a chart or a graph to see how the damn plants grow. So much bullshit in this thread and people still skipped right over the comparison video and called it flawed just cause it didnt fit there narrative but had it been the other way around it would have gotten multiple quotes.

Dude I dont google.. i have all thr lights here in question and have the real world results. You admitted you dont even own a fukin led so all your opinion is backed up by fairytale and snake oil. You have 0 experience with nothing other than the light your sucking off.I say shit you could verify on wiley or google or ncbi with enough time and an educated background.

Every time I see you post I wonder why you talk. Like what are you advertising for? Generally people who are selling something try to be likeable lololol. Your so opinionated and you think your opinions are facts and everyone else is retarded. Before I saw you post I saw the ads and I was a bit interested in clicking through but honestly I think your driving away a lot of people...

Keeps forgetting, we have been running HPS and COBs for a few years, it's not like we went and bought a light and had a decent harvest after 1 grow. Then started spewing lies. Just telling our experiences. Talking about having an "open" mind. lol

You proved leds grow weed like any other light, you didnt prove they yeild more except in your own personal situation.
Now back to science and explain where im wrong?
Explain why cmh/lec growersxare distancing themselves from led scoence claims and ego.
Explain why its a toxic market and subject
Explain why many struggle with hid but do better with led when wes all doing just asxgood as you with hps¿
At some point us real growers got bored with you and hoped you troll off, take them weak diodes with you all spaced put on a diy boardxstruggling to deliver a weak shifting overlapping spectrum and light.

You owning exspensive leds made you a troll, mot owning one makesxyou impqtial.
I thought i answered your weak putdown a few posts ago, going round in a circle to avoid any science, its bern said so unless theres any to add ya just trolling again dude...
Whats that you say...you own an led and they are hands down better than cmh for yeilds? Good luck there mate
