Are LED's That Good?

I'm seeing more and more people use these LEDs and I'm starting to wonder if they are as good as people make them up to be... what size LED Would I need to compensate for a 600hps? anyone actually used em and how does your yield compare between the 2 and also quality of fruits produced...
400w-500w of Cob led to replace a 600w hps depending how hard or soft you run them to make them more or less efficient.

Lots of grows in the led thread, but just go look at on youtube for growmau5 and watch his early comparisons from hps to COBs

Ill be sure to check that out bro

I disagree sir
If my 400 was replaced with 2 qb's
3 or 4 would easily replace that 600

And not cost a fortune like most think
400s are inefficient compared to 600s. You're not going to replace a 600 watt light with half the wattage in LEDs with current technology. That's a statement of fact.

I used to run 2 vented 600s in a 4x8 tent. I've replaced them with 900 watts of cobs and am still getting identical results in terms of weight. PCBs are badass, but 300 watts of them will not replace a 600.

An average 600 is recommended to flower a 3.5 x 3.5 area. Each quantum board can flower a 2x2.
I have my driver dimmed to about 70% so around 170-190 watts.
So even 4 boards at 340-400 watts would be a worthwhile swap imo.
And if you've already switched to cobs you know that there's a quality or density improvement on top of the heat management savings.

To replace a 1000 watt HPS, you'll need roughly 800 watts of COBs. So to replace a 600 watt HPS, you'll need roughly 450 watts of COBs. 400 would do okay. Timbers 400 watt framework would be perfect.

4 quatum boards run at 500watts will give same yields maybe a little more than a 600w hid. That's dried and cured for 2 months not wet, or uncured.
Will you will noticed over hps is that the buds are really really coated with thricones, like bricks, have a really nice taste and smell. But they are not the magical button some would have you believe. If your shit at growing it won't matter what light is used.

I didn't say any. I assume you won't be a dumbass an buy shitty led.1.5-2 gpw is a very reachable goal with led .75-1 is what you can get with hps do the math...
ROTFLMAO!!!

You came to the wrong guy with that question, ya young whippersnapper!

With a 600? I have done a SOG that went 3.41 GPW.
With a 400? Done 2.8 GPW
You don't even want to know what I did with a 250! (Aw, what the hell - 4.48 GPW)
With a 1 K - no SOG my average is 1.72

In reality, GPW is meaningless!

Now just what do you say is not a "shitty" LED? OUTSIDE of COBB's, your overpriced and overrated LED's won't keep up with what I do and not get near the quality results either!

Let this frost your ass.

Take your overpriced, overblown claims and your lack of real world results and sit on the porch like a nice young man....

GPW,, good grief.....

Yeah, of course. I was able to also cut out another 100 watts by eliminating the fan that was venting the hoods. This tent is my flowering room closest to a west facing garage door that gets roasted by the sun in the afternoons. reducing heat was important.

I have a 5x10 cmh/cob room as well, and that combo produces some amazing results.

5-600 watts of qbs may give the same yield as a single ended 1000w hps. More if you count all the larfe.
I haven't had much larfe myself
One of the most noticeable improvements I've found is even lowers are dense and frosty.
I'm not claiming better yields using less wattage alone.
But equal yield with denser bud and at considerable wattage savings.

I don't know much about QBs but they are pretty cool
I'm not a fan boy of the company and they are a pita to get. Hate recommending products that are mostly unattainable tbh but they work.
I was the biggest skeptic and I've been blown away by what I've seen from them so far.

They are hard to get? They don't produce enough of them or what?
