Which LED?

None of the above.
If you can handle some basic DIY its much better to build it yourself. If you cant DIY it could get pricey to get quality lights but you could find knockoffs on alibaba which are still better than the ones you mentioned.

 

How big is your space?

 

You want between 30 to 40 watts per square foot for flower. For an 8x8 (64sqf) were looking at 1900w-2500w total.

I would go with qb96elites, each can flower a 2x2 section:
QB96 Elite V2 Engine

For an 8x8 you would need 16 units.

For power, You can go with Meanwell 320w drivers, each one will power 2 boards in series, you would need 8 of them:

Then you will need wires, something thats at least 300v rating.
If you have a soldering gun and can tin the wire tips get 18awg stranded wire (get two colors black/red etc):

If you cant tin the tips get solid core wire (in two colors):

You might need some wire connectors, depending on if you build the lights with the driver or if you mount the drivers remotely and need wire extensions, I like these:

You will need AC plugs to put on each driver (they are not included with the driver)

And lastly, you will need some way to hang the lights. You can hang them individually with rope ratchets or build a frame from aluminum. Here's a video of such a build so you can get an idea:


Just google "diy qunatum board build" there are tons of tutorials and different ways to build em.

For mine, I built a frame from aluminum and a wire fence

 

Just buy em on alibaba.

I second ScoobieDoobis recommendation! I am very happy with my HLG Qb’s and if this blonde can get it together anyone can lol. You can trust these guys to walk you through anything you need throughout the process.
Do it ..you won’t regret it

 

I love a woman who builds led, i recently had my wife helping out and she was great all around.

 

Lol I don’t know how I managed to get it done but thank the stars I did bc I’m technologically afflicted

 

110% best idea , IMO. But I think everyone else would also agree. I have a SF1000 and I’m not saying I’m not happy with that light - but the DIY HLG QBs blow them out of the water .

 

I'm no light guru at all. But my first indoor grow going on now I've been using a Bestva 2000 and two spiderfarmer sf 600s on either side of it in a 5x5 tent. About $400 in lights and I've been getting pretty damn good results, I've actually been really surprised the way the buds have formed nice and nuggy all the way down the plant.

It's all in my earlier post, this is the driver you want (HLG-320H-c2800A) , each can power two qb96 boards.

They are much better don't worry.

 

Good choice, id had gone with CV drivers hlg320-54A and run in parallel for a bit more flexibility but this will run fine aswell.

How many did you end up going for?

 

I dont like using parallel with just two boards, if one fails all the current goes to the other board, with series that cant happen. Now if he was going with 3 or more boards per driver parallel makes more sense IMHO.

 

With A type driver dimmingydimming can avoid this. Just set the manual voltage dimming to be the corresponding to desired max amp.

You do this: properly; with a multimeter. See instruction below.
No multimeter: setup both boards in parallel and increase current to max, then voltage to max. Then slowly play downwards with the voltage dimming. Youll see that you come to a point when light starts decreasing. You wanna leave the voltage just at the point were light starts to decrease. This will be easier to see with a multimeter, f-ck looking at those bright diodes at 160w just to see a shade of less light tbh.
What this setup does is to set the driver to a voltage were the board is only able to draw as much current as you want it to draw at max. This is why i allways go with A type dimming for CV drivers. (Unless theres AB available, best of both worlds)
C2800 is good aswell, has a different type of flexibility in that you can reuse it for other peojects. But personally id say the most likely change to a 320 setup would be adding another qb for better spread and efficiency. You could do this on a CV setup but not on the CC setup, although on CC you could add 2 more and run the string in parallel.
Either way, both ways will work for just 2 in a similar way: no chance of burning your chips if you have a board failure.
