Are LED's practical for a grow room? (24 ft x 12 ft)

[Rahz]

Anyone seriously considering putting a large scale grow together isn't going to base their decision on some pictures in a forum.

Try to grow a lb with a 250 watt lamp. See what happens.

Or you can go off grid power and have the best of both worlds 20 grand for 10,000 watts of grid power IMO a better choice then worrying about if that Cob or LED will produce more cause thread after thread its not showing it is

That would cost more than my 60% efficient passive build would cost on a large scale build.

though combine the two and you have a pretty rockin system...

At the End of the day 400W of LED is not going to give you more yields than 400W of HPS, no matter what the manufacturer claims about equivalency. Unfortunately when it comes to growing cannabis, multiple tests by growers demonstrate that LEDs don’t live up to the hype of somehow magically increasing yields with far less power

 

[OneHitDone]

true 400 mh is a 400 watt mh now to mod them for double stacked vertical
but hey a closet grower will be a closet grower nice yield for 10 plants there buddy

Final weights off 10 of ea:
Sweet Black Angel - 2.3oz total
Cluster Bomb - 2.8oz total
Nothing to write home about yield wise and won't wast my time and resources going that route again but had to see what it would do.

Lol, those are not plants. More like flowered popsicle sticks.
I am on track for attaining my goal of 1lb from a single 460W Inda-gro setup

LOL, now you're just talking shit. a 400w bulb isn't as efficient as 600 or 1000. A 400w COB based lamp would easily kill a 400w bulb grow.

But like I said, you can spend your time looking for pictures on internet forums or you can build a small rig with at least 140 LPW efficiency and find out first hand what it's capable of.

Really. If as they say "spectrum isn't important" (which I agree with for the most part) then all they need to do is a bit of math to get the facts.

Or maybe Cree and Bridgelux datasheets are full of lies?

You lucky bastards im at 28c/kw. Except for mongo, 4000 watts at 372 hours at 600$ holy cow, i thought my island electric bill was retarded.

Its .34 or .37 a kWh i forget which one.

What are you considering large scale grows? I mean if the 2000 dollar led kicks the fuck out of DE lamps then on a low yielding og your going to pull more then 8 units if were trying to take the place of 4 1k lamps. And if there not going to make their decision cuz of grow journal pic then what are they going to make their decision on?

science and hard numbers maybe. ..or you can blindly follow what people insist is the right thing with no actual evidence just because they say so kinda like a religion hmm. ..

he's made it very clear he doesn't understand numbers and won't answer any of the questions that reflect his claims even if i wasn't pro cob id consider it now cuz Darth dork hasn't proved shit besides "mines bigger then yours"and his one god to rule them all philosophy (i mean his magical lights that defies science)

Yea, im not following you really. Your just trying to shit talk me again. Your probably not in a position to make a move like that, so you really wouldn't know a whole lot about what your saying. Once a week you try to shit on my parade.... Nice job bro. Last time your boy had to check your ass, then you apologized and now here your at it again. Thanks a lot bro....

just trying to give you some help maybe you can stop smelling my ass and get an opinion of your own and i would never apologies to you but I'll tell you too suck it again

Hold on to that blind Faith mighty hps growers it's gotta be the magic in the arc that can only grow mj
edit:i have nothing to prove to anyone i proved it to myself and that's the big hang up anybody who had tried both is sold if that isn't a little hint hint idk what is

Your ruining it for everyone making and talking about diy leds. Your worse then the discussion at hand. Tell us what you mean by smelling your ass.

Mongo i look at it this way these religious LED growers tend to think there shit is beyond all and us old fucks that have not converted , to Cob or led do not know what the fuck were talking about ..but the truth is YES LED's have been out for some time now pretty simple math really look at what people are pulling and sure the fuck is not even close to DE fixture you just have to look around thread after thread usally never completed as op fucking disapears in disappointment..
and the ones that shine have been sponsered by a LED company go figure Bias at its finest

HERE lets set the RECORD STRAIGHT REALSTYLES POST THEM COBLIN PICTURES.. ,, PULL THEM PANTS OUT OF TENT AND TAKE SOME SINGLE SHOTS OF THEM STRETCHED TO FUCK PLANTS CMON WE KNOW YOUR REAL PROUD OF THEM 2 - 3 - 4 COB UNITS @ 800 BUCKS A PIECE THAT IS A EQUIVLANT GROW TO 1 DE GROW
The truth is i probably have more lateral growth under 48 watts of T5's

 

[Red1966]

Or is the HPS route the way to go when dealing with this size? (Im looking to avoid potential heat problems and high electric bills)

LED can help you with those, but the cheaper ones aren't efficient (more heat) and don't last very long (more expense). The better ones are very expensive.

Your an idiot my plants are in trellis and why would I disturb my ladies? You'll just have to wait for my weekly update which is Tuesday the 25th and it will be the first day of week 5.

Is this what you want...


They finish great too...day 45, 47, 55...
