DIY with Quantum Boards

So,
RE: HLG constant voltage drivers. Eliminating the potential for thermal runaway doesn't apply to more than one board, right?

Say, two qb96 v2, and an hlg-320h-54a. Went with CV/parallel for the ability to add/remove additional qb (possibility) and can use inline meter (was the thinking at the time), and thus chose a-type thinking I could at least 'limit thermal runaway risk' (Io and Vo adjust). Apparently this is not the case.

So, I'd like to ask for recommendations;
HLG-320h-c2800AB?
HLG-320h-54B? (320h-54AB would be the same situation as the 320h-54A, as far as TR, right?)
Inventronics EUD320S320DT? (or some other inventronics driver).

If anyone would like to share advice and suggestions it would be much appreciated. Was hoping to get some of these done in the next week. Now it's going to be months...

Thanks.

I was thinking about veg, and possibly use for a week or 2 of flower and move into a larger tent w/3000k 288's and qb96e's. I think the 3500K would be a good in between for transition. I allready have 2 older qb96 4000k strips for clones/seedlings. I am not really restricted by height as the transition would occur.

Yea, 4k because its probably gonna end up for mainly just veg, right?

Yea, better than 3000K. Slight compromise.

The 3500K is actually very close to the 4000k board. The have about the same amount of blue, with the 4K having less red. I have been running both for some time now and see very little difference between the as to growth or flowering. I'd say the 3500K has a slight edge in bud production

I am just about to pull the trigger on 4 of these qb120 in a 20-24" x 4' x3' h space for veg and early flower. Just struggling on the colour of either 3500k or 4000k. I was thinking 3500 ( a bit better for flower still good veg ) but 4000k better for limiting stretch. Any input is appreciated

You can limit thermal runaway with CV drivers by setting max voltage while the light has no air movement after heating up for 3-4 hrs. Use the VO screw to turn down voltage until you start to slightly dim it. Should limit thermal runaway.

P.S. only works on A type driver. Possibly AB type as well.

Quick Change :

Decided to mount up a spare QB 304 4000k ( 150w ) dimmer to the QB96 warp rig for now. Didn’t decide if I was going to do the strip
lights instead of the UV lamps I have attached. Lurking CUTTER website for some options.

Anyways .... Power is now 470w capable for this 42” x 24” x 60” tent . Right now I’m dimmed to 380 ish.
Easy to change when needed. Temps are still nominal but hella dry lately ( Rh ) so I may have
to address that .... HOT HOT in California
:fire::cuss:

Plant update later on ......

anyone have any pictures of plants that are getting too much light?
just added in two more lights and now seeing some tip burn and copper spotting. I also just transplanted though

Picking a driver is harder than one would think. Its nice to consider adding a 3rd board to the 320 54a.

I think CC drivers are safer from TR...I do believe.

I am doing some changes myself. I currently have 4 - 185 54a drivers on 4 qb96e's. I a just ordered 2 more qb96e and will be running 2 boards per 185 54a. I had this wired today and the 2 boards pulled 2.1a 255 watts from the wall on the 185 54a. The driver was hot to touch but not too hot like my 240 c2100 get turned max. I will probably dial them back a little. I have 1 Rspec coming too which will be replacing the center board in my tent, It runs on its own driver. I will update pics later when complete.

Same here last run. dial the lights back or raise the light. I knew I had an issue when the nicest looking plant was in the corner with least light.

Looks like a slate 6 heatsink. Those are beast. I was sent 8 of them when I initially ordered. Blue anodized. They are like double the weight+ than slate 2. Perhaps with the V2's they were overkill.

sweet. I also did just transplant also, maybe the combo is what did it. I backed the lights up and added a humidifier now and they seem to have grown alot today!
I'll post some more accurate info if it gets worse, but i guess its time to add cal-mag.
Anyone recommend anything besides epsom salts that I may want for under the qb288's or will epsom be fine?

Love them ... they run hella cool . I should have grabbed two more so I could upgrade my QB/cob rig .
Some question 4000k in flower .... I find it works well and it isn’t the first time I flowered with that spec.

This from last year using 4000k in similar setup ( open space room ) ...

IMO I am bumping the intensity and spread , and my plants seem happier for it due to spectrum mixing. Not too crazy
way to think about it as some new clone boards are shipped with 2700k / 4000k split rows and 660 NM . Technically
I’m adding more of a blueish component than all reddish. And it fills up some voids ....

I have a 3000k 90cri and a 3500k board that can be switched in place if I need to but like the mixed spectrum .

Really liked the 304 .... hopefully V2 ? @Stephenj37826
Any more Slate 6 ?
Mixed ? ..... UV ? ..... just throwing it out there. Lol

:bigjoint: Peace
