If there wasnt a side by side done on a plant then the study is irrelevant and their probably trying to sell you something. LED's are overrated in my opinion.
How many plants can I grow with a 750 watt LED light?

Definitely not, dude. COBs are completely different animals. They were invented to replace HPS in highbay/lowbay industrial applications. Trust me, you're way behind. Even HID (HPS/MH) users admit they add up.

You usually have to build them yourself, but they have a few vendors here who are site sponsors of RIU. We also has a user who I believe became a vendor? Growmau5?
Cree, Vero, or Citizen are the ones you want to go with.
I use Tasty.

I know what it is, but its strange how there isn't any actual side by side grows with all these benefits they claim. Show the finished product thats how I will believe it, thats how you prove something. Im not behind at asll, you just bought into the scam man. Have you completed a grow with your COBs yet or is this your first? If so have you compared your grows to see the difference and whether the difference was big enough to spend 3 times the money on a COB led than an HPS. Isnt this about saving money and maximizing yield? Plus when one of your cobs burn out itll cost you about as much as a 1000 watt hps setup to fix. So I dont see the benfit

theres been several side by sides here on riu. the most recent i saw was just a week or two ago. their results were that the hid gives better yields and more solid buds, the led had more frost and finished about a week earlier.....which seem to be the results most people get

I sold all but 4 of my COBs and other LEDs and reinvested in HID's. Best thing I ever did. I now am doing a hybrid grow using HPS, MH, LED, Fluoro, And UVB bulbs and so far its my best grow yet.

I cant argue that when I did a straight LED grow the quality of the buds was far superior to any other grow! Yield suffered though!

So you haven't seen any side-by-side comparisons, yet you are sure it's a scam?
That doesn't make sense. At least keep an open mind.

You probably weren't driving them hard enough. Probably between 700-1400 mA per emitter.

My mind is open, its just that these types of claims need to be proven to become worthy. Ive grown with LEDs ALOT and all Im trying to tell you is dont believe the hype man. Do what you want, Im sure you grow bomb shit, but Ive wasted alot of money on this shit and I know a thing or two about the LED hype thats all man.

This was a few days ago. One of my two plants under 3 harder-driven COBs.

Full of shit. What brand and model COBs and what driver did you use?

Im not even talking about the cheapos, those are fucking worthless and better a paper weight than anything. What Im saying is a 700 dollar kind led thats drawing 400 from the wall will give you approximately the same yield as a 400 watt hps that costs a 1/4 of the price and draws the same wattage.

I have been getting capitate-sessile trics since day 3 seedling on both. And look at that thick ass manifold.

I run a similar setup and get decent results. My buds don't stack up like they could if I added more light, but I couldn't be happier with the quality. Now that temps are lower, I'm going to run two 400w MH + 600w HPS (enhanced spectrum) and see if 1,400 watts works better. I need the heat anyway, so why not give it a shot?
Another option would be to run three 400w MH.
Hmm...

I used cheap chinese imports, I used Black dog, I used Kind I dont remember drivers and shit. I didnt get that involved in the science of them, I just bought into the hype at the time. I mean we can go back and forth all day on this bu the simple fact is that all the hype of these top of the line LEDs hasent been proven in a side by side with HID, and for good reason, cause its Hype thats it. There may be a day when LEDs can compare to HIDs equally all around including cost but that day isnt here and HID has been proven multiple times in side by sides to equal or outperform LEDs of the actual drawing wattage.

LEDs do produce frostier and better tasting buds, I wont argue that.

Sour Kush/Headband under LED is the tastiest weed I have tasted tried, the richness was intense.

T5's and t8's give better frost than hid which would be what i equate the extra par spectrum as. The hype about led quantity and par is bs in my eyes as even green light will grow a plant with enough of it.
Very refreshing to hear your going back to hid, heat is rarely a problem in the Uk (maybe three months of the year at worst).
I never looked at side by side comparisons more what the best growers were yeilding under hps compared to the best of the led grows. Hps is a winner all day long but like you i am more open minded and leds still do a darn fine job, minus all the hype and tech confusion.
