It sure would help to be able to see your replies @growmau5. People could answer their own questions just by your replies to others.

u think 4cxb3590 @3500k with a meanwell hlg240h-c1400a is over kill for a 2×2 tent????

Love the video. Im wondering if prices have changed in the last 2 years since this video has been uploaded. The HLG-240H-C1050B on the Kingbrite page is like $5.00 and on Mouser its like $90.00. As a noob am i missing something here? Or is it just a more common unit now? Sorry if this has been brought up before...

Your music in the beginning is to loud >_<
Im watching your videos at work, but no one should notice it. :'D -
Do you sell a manual for assembly?

I'm completely new to this and want something for a 4x4x8 tall tent and that 12 cob looks bad a$$. Would this light be a good fit for that space? Would it be to much? Can this be used for vegging and flowering? I'm sorry for all the questions, I'm on the fence about buying the chilled diy 450 or building this... Thanks for all the effort you put into these videos /lights

Another amazing video, thank you so much, very educational! Can you do a video about how to build a COB light with as close as possible spectrum to McCree spectrum? Would love a video about COB spectrums, include kelvins, CRI, nm etc.
Let`s say COB`s spec sheet says it gives 100Lm at 700mA. Will it give more than 100Lm if I run it at 350mA? Or whatever Lm are specified on spec sheet, its a maximum it can provide?
What if I run COBs are higher amperage (to get more lm), but I`m able to keep COBs very cool - will efficiency still suffer? Do COB`s loose efficiency just because of junction temp or there is more to efficiency than just keeping them cool? -
I mean in the summer we got here 33 or 34 degrees

I have a question for you I'm wondering about the Heat I have a tent that is one meter how hot is going to be inside with six cob 3590 3500k
-
You shouldnt use rock resinator
-
I was wondering, could you use anodized heat sinks instead of extruded aluminum sinks and skip the fans or will you definitely need fans and a bar setup for the 12 cob setup?
-
Bam!
-
In the 12 Cobb 4 x 4 set up running the two Meanwell 1050, since they're already runningextremely efficiently and it low wattage would it
be an issue dimming these -
you're a great teacher
-
Would this set up with the 12 cxb's grow canna without the reds blues n pinks or would you definitely recommend adding some other colors
-
Hey so I'm guessing your high end light is actually 12 cxb 3590s in one light? I'm having trouble understanding 2 drivers to 3 separate lamps. I'm pretty sure you meant 2 drivers and not 3 so just wanted to clarify!

I don't know if you've been a professional instructor/teacher, but have to say your videos are so easy to understand and that's because you have a talent for communicating ideas very clearly and succinctly. Thanks for the work you're doing and taking the time to help people like me who really need this kind of help ;?)
