Advice building a CXB3590 red flower set-up with additional intergrated, or seperate 5000k veg cobs?

Hi guys, I am new to DIY LED and i am just after some advice please?

I'm trying to build a Cree CXB3590 array for a room of 2x2m (6'6"x6'6").

So far is have 36 x CXB3590s (12 x 2700k, 12 x 3000k & 12 x 3500k)

I'm splitting the 36 cobs into 6 rectangle fixtures to fill the square room, composing of 6 cobs each fixture (2 x 2700k, 2 x 3000k & 2 x 3500k) with a dimmer for each fixture.

I've bought the kit from Cutter. As some of you may know Cutter do not sell Mean-well drivers, they sell Zhonhen PF-P400CC-C140-S-DM 1.4A 314Vdc drivers. Are these as efficient as Mean-well drivers?

As this set-up is going to be predominantly geared up as a flowering light, I'm looking into purchasing some Cree CXB3590 5000k's to veg under. How many would you suggest for a 2x2m room? I was thinking of buying 9 x 5000k's, bunching up the pots to one side of the room into a 2x1m area. This would be covered by 3 of the rectangle fixtures and adding 3 x 5K cobs into each fixture, totalling 9 x 5000's?

Will 9 x 5000k cobs be sufficient?

If so, would you do this, or would you build separate fixtures that house the 5ks to allow me to have flexibility to move the veg lights around more easily?

I've attached a pictures, one of them is of the fixture that I've built. It has 2 x 2700k, 2 x 3000k & 2 x 3500k cobs installed. I've put 3 heat sinks to show where i was thinking of adding the 3 x 5000k cobs.
I've also created a collage of where the 6 fixtures would hypothetically be on MS Paint.



If you've got this far, many thanks and I look forward to any responses!

well looks like youre already bought into the 3590s which while not the most optimum choice for a rig in 2017 will do what we need them to. curious why you mixed 2700, 3000 and 3500 instead of going all 3000 which is the same overall spectrum but more uniform.

probably or @welight wouldnt sell them.

in a 2mx2m you wont get great coverage with 9 cobs but its doable if you hang them high enough. 5000K+ your flower light would work great tho

if i was doing separate veg lights id prob go 3500k 80 or 4000k 80 over 5000.

id use 5000 if youre mixing your flower lights in with veg

Yes the ZPE drivers we have tested next to meanwell and they are excellent, the 400 watt for a similar price to MW320 give you a little more volts, we have sold several thousand with kits and I think I have had 2-3 back that failed, so efficient, reliable and cost comparable. The general sense here is 4k over 5k for veg however 5k in 3590 is DD bin so better efficacy, love your build so far
Cheers

My first all veg light that I built (LED) was a 5K 3590 light for one of my 3x3 in which I ran four of said cobs at 250 watts. It was a monster and aside from the 6500k citizen 1212's closest thing to my beloved Blue MH for veg. You can ask @ttystikk how the light performs as he's had it for a while now.

Found a pic of the light:

This light kicks ass, takes names and slaps your mammy.

It's so good it gave me amnesia, leading to me forgetting about your situation and asking why you went back to HPS the other day lol
