Thanks. The entire thing is 24x11 so not much distance to cover. Nervous about soldering to the LEDs. Almost there!

Yeah the reason we went this orientation was because of the base of the coolers. You can see the raised portion of the heat sink with a straight edge that made lining everything up square really simple. Didn't think about the airflow right away but once we did and hooked up the fans, no problem...

Got the frame built! Still need to mount the LEDs and wire everything up! I'm loving the L bracket idea.

Got the frame for my 4xCXB3070 set up. Now just need to wire everything up and mount the LEDs! Hopefully gives you some ideas if you move from the individually hung coolers.

Nice man. Sorry, I didn't go to page 2 yesterday before replying, I'm now seeing the pics and all that. Lookin good!! I just love that fact that the 4x CXBs and that drive match so perfectly. For mine we are going 2x2 supported by aluminum L brackets cross braced in the middle with the driver in...

Literally exactly what is sitting on my kitchen table right now except apline 11 plus heatsinks! Should be putting it together in the next few week. I plan on making a thread and also very interested to see how yours goes. What will you mount everything to?

Seriously about not running the voltage to dim!? Thats excellent!! Do I just hook a 100k pot to the Dim+ and Dim- leads? I am running just 1 HLG-185H-C1400B. Thanks for the suggestion on the fan psu. I have one in front of me (micro usb charger) that is 5V 1.1 A. That should work, right?

I got 4x CXB3070s yesterday from digikey. Might be a week or two till we finish up the light though. Hopefully it turns out and I'll def post some pictures. Unrelated, I have some questions regarding powering fans. I have 4x .6A CPU coolers. I also got the B version of a Meanwell driver which...

Well they are 54 days into flowering so not really much new growth happening.

Thanks man, thats what I'll do. Hopefully I can make it a few more weeks..

I really hope you are right. I usually water once a week with half strength nutrients and the past two weeks I have given them CalMag too. I migggght have slowed down the one bad plant a bit but it's hard to tell if it stopped spreading in that one plant. I have heard that white widow commonly...

Here is an album of pics http://imgur.com/a/pHhYT White Widow 51F LED lighting FFOF Soil 1/2 strength FF 3 pack nutrients It started on one plant maybe 3 or 4 weeks ago. It has very slowly spread throughout the plant. Notice how it follows the veins of the leaves. Just yesterday I noticed a...

Digikey said they would most likely arrive at their warehouse today 3/5 and would probably ship them to me tomorrow. ETA to my house would be Tuesday or Wednesday next week. I only ordered 4!

I couldn't find the CXA AB in stock anywhere so I got the CXB AB. Plus I can run 4 instead of 3 because of the lower vF. My first grow is almost done and I want to have this thing ready for my next grow and the clones are already getting big!

I ordered 4 from digikey yesterday :cool::cool:

Recommended way to secure the Cree CX series to a CPU cooler? Would this LED holder work? http://www.mouser.com/ProductDetail/TE-Connectivity/2-2154857-2/?qs=%2fha2pyFadugAgPLTaG4bmekBcEb4TFyEA6KuG77EqLSR07yT7niOiA%3d%3d

Welp...good news I think. Digikey is getting the CXB3070-0000-000N0HAB30G in stock tomorrow. They said a few days for shipping ($5) and I should have them by Tuesday or Wednesday next week. Hopefully the HLG-185G-C1400 will power all 4!!! Super excited.

Yep, I order 4x CXB ABs from digikey...we'll see what they say when I call to confirm the order here in a few minutes. I actually saw your post saying you could do 4 CXBs on the HLG-185G-C1400 and "Cree must be watching this thread" 8) Hopefully your (and my) calculations are correct. If not...

Do you have an example or link for these? I plan on using the alpine 11s so something those could mount to easily. A place for the driver would be cool too. Maybe just a wood board with 4x eyelets?

I've got few quick questions. This thread is ridiculously helpful already. Would it be a terrible idea to veg and flower under just 3000k crees? Has anyone tried that? This is dumb but...if I can get 4x CXB3070 ABs and power it with 1 HLG-185H-C1400B, I need to wire the LEDs in series, correct...
