(4)CXB3070 & Meanwell HLG-185H-C1400B driver? Want to order tonight!! Need Input!

[apoulin]

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.

Looks nice man! gives it a nice clean look for sure! I will definitely be building something more permanent when I move, Cable management will be so much easier with something to actually mount them to. I thought about using the thin metal L shaped beams with holes in them (sorry not sure if there is a name for that lol), that way I can have a way to adjust/add/subtract my led modules, kind of like an erector set looking mount for all types of mounts for LEDs/fans, drivers and wire management.

 

[apoulin]

So I shut the windows and fans off, moved the LEDs to about 14" above the canopy. I also added the 4 Vero 10 5Ks that I have to add some extra heat, the air temp is now at around 73F 60% humidity. I noticed that things did not get any worse, things seem to be improving. Some of the leaves are perking up and starting to not look so curled up on some edges. There has been some new white root growth as well, I have the res at 69F and 450PPM.

Lucas Formula w/Flora Micro/Bloom
0-5-10 (G-M-B)
Target PPM - 600
Before PPM - 300
After PPM - 470

Add Back
(Target/Current)-1*5ml(Mirco)*10gal(res size)
(600/300)-1*5*10 = 50ml Micro
Bloom = 2xMicro ------> 100ml Bloom

I added 25ml of Micro and 50ml of Bloom to water I topped res off with, PH ~6 after everything added. The PPM were at 470, which is ~correct because it was a 50% nute strength by adding the 25ml of Micro and 50ml of Bloom, instead of the 50ml Micro and 100ml Bloom called for?
So by adding ANOTHER 25ml of Micro and ANOTHER 50 ml of Bloom, I should be at my target of ~600PPM??

Sound about right? Just trying to make sure I get all of my math and theory double checked this time!


EDIT:Update, placed a blanket over closet door to hold heat in. Worked like a charm, running about 77F air now. Still no fan other than fans on heatsinks, leaves still seem to be improving(tips uncurling)

 

[apoulin]

Plants seemed to like the higher temps, been trying to keep it around 77F 60% humidity and they are opening up a lot more and seem to be growing quicker. There is a lot of foliage so I will be trimming that shortly and taking a few clones to give them a little more room. The areas where leaves are overlapping is causing some condensation to form, I definitely want to get rid of this moisture before buds start producing. I also have been trying to remove some of the humidity, might need a small dehumidifier.

They drank maybe 3L of water (guessing at this point) and the PPM went from ~470 to ~400. I will be using the above addback calculation and adding that amount of nutes to the 3L of water and add that to my rez. Which should return the volume to 10gal(rez size used for calculations) and have all of the proper nutes to take me back to ~470 correct?

So
((500-400)-1*5ml(Micro)*10gal(rez) = 12.5ml Mircro
Bloom = 2xMIcro ----------------------> = 25ml Bloom

Should put my 10gal rez @ ~500PPM

If there is visible condensation that could be an issue. Back off the RH a bit. If too much moisture is in the air they will have a hard time transpiring.

Yes, visible only between the leaves where they are overlapping. I am having a hard time getting it low while trying to get my temps up without adding a designated heater. Sounds like I should invest in a small dehumidifier for my closet

Been nervous to turn my fan back on lol

 

[Scotch089]

A small heater will sap the moisture out of the air but keeping it well away from the leaves is a must

 

[apoulin]

Turned fan on low, temps still 78F. Will be shutting fan on when lights go out.

Def getting a small heater/dehumidifier in the next few days if I can't get it regulated

You can find them for $15 or less at restaurant supply stores. A thousand predrilled holes so it makes layout a breeze.

I'm slightly confused I see how the driver could be mounted but on a heatsink with an LED on one side and a fan on the other, how would you mount it to any of the holes? Unless maybe cut the pan away for the LED to shine through(Heatsink sitting on top of pan)? Get a bracket that attaches to the side of the heatsink and mount that to the bottom of the pan, giving clearance for the fan?

lol or am I missing something here

Skinny nuts and bolts, suspend the led/heatsink/fan combo, leave about 2" from the underside of the pan so the fan can pull air.

I see now, yea that would offer the type of flexibility I am talking about!

On the top side you can mount a junction box and outlet, so you can plug in a DC converter on the back of the sheet pan to operate fans.

Nice pictures too! Yea I might have to "borrow" your idea! getting everything in one place and cleaned up would be fantastic. Pretty nifty lol If a strainer and a cookie sheet had a baby, it would be perfect for mounting LEDs to grow pot

The other thing of beauty is that this should be about the perfect size for my rectangle tub! Thanks for stopping by and throwing your 2 cents!

 

[apoulin]

So I have some updates for anyone interested.

First off, plants have really been looking healthy and growing every day. 4/6 females, 2 still haven't shown.

I said I would be taking clones and clearing out lower leaves, today is that day!
I spent ~$20 on a 5gal bucket($5), submersible pump ($9), sprinkler head ($4), 1-2" hose ($.50), had reflective tape, jiffy humidity dome and clay pebbles. My thoughts are put clones in here and through holes in bottom of dome, ~60 holes. I will be using rootech cloning gel

The clones will be in the bucket and have (4) vero 10 5ks on them

On my phone and pictures aren't as listed lol sorry

1. The ladies
2. Roots gaining a lot of mass
3. Stems getting fat
4. Pump connected to 1/2" connected to sprinkler head
5. Water filled under sprinkler head (~3/4 full), seems to get everywhere sufficiently wet
6. All wrapped and dome installed with pump working inside

 

[apoulin]

So I have some updates, all of the clones are still alive but none are showing any roots yet.

Plants are looking healthy and didn't seem to mind the trimming I gave them.

Roots still looking healthy

77F @50% humidity
ReZ @ 73F and 500ppm

Made a mount for my leds from a baking sheet.

Spent $10 at Walmart for all supplies needed and took me about an hour. Looks a lot cleaner, a lot easier to maneuver things around too lol

What do you guys think so far? Getting some nuggage too!!

Hi. I'm doing the exact same setup as you, making two of these lamp builds. Bought 8 cxb 3070ab+ cx30 array holders, 8 arctic alpine 11 plus and 2 HLG 185 c1400a, but I'm not very good with electronics or wiring, so I hoped you would be so nice and explained that bit for me? And do i have to grind down the cpu coolers to get the led modules to fit on them?

Haha really just diving right in. This is high level... I might be able to do more once I get mine wired up.

So to start, you will need an AC power plug wired into the Mean Well and another wired into a AC to DC converter for the fans. For the converter, I'm personally just using a wall charger from a router or something. It's 12v ~1A. 5v will also work if you want to run the fans a bit slower. The Mean Well has 3 wires that will match right up to the power plug. For the AC to DC converter, will need to split wires off of the ACL and ACN and run those to the leads on the converter. There you have your input set. Now you need the output. Wire the Mean Well up to the LEDs in SERIES (you will need to do some research if you don't know what that means). Then wire up the fans from the AC to DC concerter to each fan in PARALLEL. Since you got he A version of the Mean Well you don't have to mess with any potentiometers since it's already built in. It's a bit overwhelming if you don't have any experience with electronics / soldering but in all honesty, it's pretty straight forward.

Hope that helps. I may take some pictures as we wire it up that might help you visualize it. That would be in it's own thready though.

You will not be disappointed with that setup!!! I will be buying another set as soon as I can lol

I do not grind heatsinks down or polish them, I know some members on here do. I have not had any issues with the heatsinks as they come. I simply remove the pre-applied thermal grease with an alcohol soaked towel. Dry the heatsink and apply adhesive (I did not use led holders) and apply the LED.

I have mine wired in series so that the voltage adds up and they share the same current. Series wiring is simple and a quick forum search you can find tons of diagrams.
36v(each) * 4(quantity) = 144v @ 1.4a = ~200w

Good luck and keep us posted!!!

If you take a look at my other thread "my first cxa3070" I have a lot of pictures posted for my first LED setup. That might be of help
