High power COB -vs- hps vertical shoot out

I can take a picture today, although I wouldn't call it a money shot... more like a loose change shot.

Yes, we absolutely coup slam a bunch more LED in there but the point was to SAVE some electricity...

And to the dude debating about led vert l... I see your point, but that isn't what you said initially

It may not be what you read, but that is what I said.

Anyway, I have been giving this some more thought, particularly the reduced distance from the light source part.

Sure, you can reduce the radius of your ring and perhaps add more towers in the same room. But what if you took that to the extreme?

There are many cob chips in the CXB line and they are all very efficient even to low single digit wattages. So why not grow a jungle with micro cobs everywhere?

You would only need as much room as it takes to work and the rest could be greens. Can't think of a more effective way to maximize a room.

There has been a lot of great t5 and t8 led replacement bulbs available lately. Look for at least 130 lumen per watt or better, that is around 40% efficient. The would be a great choice, since the plants could grow right into them (maybe).http://www.ledsmagazine.com/ugc/iif/2016/03/18/green-creative-releases-dlc-qualified-plug-and-play-t5-ho-dir-led-tube.html
If you still want to play with rings, these would work, but I don't think it is as flat panels.http://www.ledsmagazine.com/ugc/iif/2016/03/18/saving-the-environment-one-communitybulb-at-a-time-megaglowledcom.html

Ummmm. What? ... spread 1,000s...yes 1,0000 of leds everywhere? Yeah, that sounds AWESOME!!!!

I don't have a huger bone over LED. If I had to guess, right now the HPS is fucking thumping them.

Yea, was just thinking out loud about how to maximize a given volume.

So the LEDs are having a hard time keeping up, huh? Gee who could have foreseen that.....

"Vert is one area that I think the COBs make less sense."

That is the first sentence of my first post in this thread. You know, the one you didn't really read and responded all butthurt with a math lesson that addressed nothing of what I said.

Time will tell, but it certainly seems like the hps buds are larger and somehow slightly more developed.

I think I do need to pick another HPS reference plant however. The one we picked has 3 bare bulbs and one bulb with a reflector (because it is the bulb on the edge of the system). Meaning, that plant is getting a little more than 1k worth of light.

your design is why it failed. you need a flat screen vert grow to take advantage of the cob's. putting them on each corner of a round plant was asking to fail from the start. ask @ttystikk how he is doing his which is the correct way.

You can ask me all you want, but I won't have any answers for at least another month. Not every solution works in every situation, every time. Sometimes- shit, most of the time- you learn more from things NOT working as expected!

Is it because these cob lamps won't penetrate a mega plant? So people have to change the way they've been gardening for years for these cobs to not get slaughtered? This is bad news on the commercial front.

Agreed you learn more from failure because you don't want that shit happening again.

You guys that are saying that A. I have a round plant and B. It is a dense canopy are completely and utterly fucking retarded.

Look at the pictures asshat. The plant is trained to a FLAT WIRE FENCE. FLAT. IT'S A FUCKING FLATLAND grow... on its side. Are the lights on the corners? NO. I'm all about constructive criticism, but criticism from shit stains that don't even understand the set up?
The cobs are going to go into a pre veg light system. At least now we know, we bought the best chips and ballasts that they make, and they just didn't deliver.

It's entirely likely that any number of things individually or together could have colored his results. That doesn't mean that A. COB LED has no future or B. that @legallyflying did anything 'wrong', it means that it wasn't a good match for his growing style. That's important, because our growing styles are very much tuned to the equipment we use to do it with.
