Opinions on how to light a 10x10 flower room Quantum, COB or Both?

If you average over 1GPW, I have seen multiple threads now of users running COBS getting 1.35-1.8 GPW+.

Perhaps look at some Citi/Vero Chips. If cost is a concern, go with the Citizens, latest 6th gen 1212.s are going for around $11 each compared to latest Vero 29 at $25...

Going with both QB and COBS is likely to just make the grow room more complicated....

Also arnt those QB a large fixed size? if so would'nt that make the COB a better choice for more light uniformity and scaleable design.

thats not a correct comparison, 1212 is same class as vero18, not 29

Just because you have 800w of LED does not mean it can easily replace a 1k DE. I am still waiting on COBKITS to produce an efficiency chart readily available for his customers of all the chips he really pushes.

not sure why i keep taking your bait but is there any chip vendor out there with an accurate efficiency chart for any chips? is there any manufacturer out there that actually takes the time to measure real test data of different manufacturers? im not aware of any... you probably still believe that cxb is 56% efficient at 1400 mA in any real-world condition when it has yet to be demonstrated at all. and thus "anything under 55% is unacceptable" based on your ability to know what is right for everyone.

I get it you have some sort of troll condition, you havent posted anything in 2 days that wasn't a direct attack at me. that's fine. youre entitled to your opinion. Youre also welcome to do your own tests and present them as you see fit, nobodys stopping you. you can spout BS about "how im wrong" or you could put up some actual data to refute it. Not that i expect a response to this comment. your troll tactic is to repeatedly ignore when you're called out for BS, and pick up some new irrelevant incorrect assumption and pick at it. its pretty tiresome, tbh.

I see why so many people are venturing away from RIU. It has turned into the troll city of 420 around here. Sad days.

How about putting a budget out there for us to work with? You will get a number of validated options to consider. I like your priority list and based on that, I would go ultra high efficiency setup putting a lot up front into quality cobs.

I want to build it in chunks, spend about $1000 at a time and keep adding to it

Does Digikey provide an efficiency chart? No
Future Electronics? No
Mouser? No

They provide links to what the manufacture publishes. There is no obligation for them to hold customers hand and figure out the design for them. People charge money for that.

Not sure what your beef with Cobkits is or if you are just some stubborn dinosaur that thinks hps is the end all to be all.

HPS is end all? Not hardly... I did the blurple thing like a dumbass then moved on. Running COBS at efficiency levels no better than DE is stupid and pointless. We are WAY past that but whatever. I built a light 2 years ago that was 45%+ efficient with COBS. Here we are 2 years later and people are eating up cobs at 49% efficiency and lower like its the 2nd coming of christ.

And notice no one buys from those 3 companies? ;) Ill be done though. Nice garden sixstring!

All the leading edge guys are going with quantum boards for reasons of price, performance and efficiency.

If I was starting now that's all I'd buy.

Bleeding edge is those who are trying to making qbs using cobs, aka high density cobs!

things aren't always mutual exclusive and if you can match two great things to make an even better thing, bonus. Plants already do it as shown with the Emerson Effect, so if a simple plant can figure it out, we should be able to.

theyre definitely great tech. ill be stocking them when the new batch comes in. options are great

First vendor who can offer them in custom sizes (panel) so people can easily replace them in whatever chinese blurple they have is going to be pretty wealthy.

Start with the most common Mars whatever unit and stock those sizes.

I think high density LED is a bit of a blind alley for our application. Wide light distribution improves efficiency, reduces the need for heatsinks or other cooling expense and cuts cost. These trends explain why plants and growers alike are responding so well to quantum board style technology.

Think of a film, similar to something like mylar that you could roll over a surface and plug in to create light.

That's where we are headed. Efficiency is the key to that reality.
