Will this 6 COB Vero 29 Rig match a SE 1000 Watt HPS and will it be as cool as a QB?

This would be six Vero 29s for $440. The other alternative would be 4 QBs or 5 QBs. The cost for QBs would be around $500 or 600.

Will the 6 Veros be as cool as QBs which run at about 74 deg F?

You haven't mentioned how many watts each chip will be driven by. That's going to determine the light output, the efficiency and the heat emitted.

If you drive 6 chips hard enough to compete with a 1000W HPS lamp, I can pretty much guarantee it will both less efficient and much hotter than a quantum board setup.

You'll need some really big fat heatsink to reach this temps passive with a COB driven @120-130w, Lol. And if you want to compare it to a DE1000w you have to do so with only 6 COB's.
And like @ttystikk said, it's not very efficient too drive a COB like a Vero29 so hard (less than 50%) so you produce more heat.

You need at least the double amount of COB's to spread out the heat evenly and also then, the QB are even better in terms of cooling.
COB's and QB will produce the same amount of heat when driven at the same efficiency point so you need much more COB's to do it. Maybe 25-30pcs. @500-700mA each for the same lm/w output.(~55% system eff.)
It's the spread on both sides what makes these boards so special ..
But comparable products with the same 561c diodes like Samsungs H-Series strips are unfortunately also not cheaper..

He's comparing it with a SE though.

Two of those "VERO29 Triple COB Array Kit" with the 2.1A drivers should be about 1200 PPF.
That should match an old 1000W SE.

But it seems like there are already new SE HPS bulbs that can put out 2100 umol/s

Probably about 1700 umol/s after reflector losses.

quick question.. would one of these: http://www.rapidled.com/vero29-triple-cob-array-kit/ be a lot better than the four area 51 w90's i'm using right now? the four w90's are 95 watts each (i believe) but the chips are smaller and two years older..

At the same current(2,1A) maybe 5% more eff., at 1,4A maybe 10% better, COB based of course not the whole kit.
Unfortunately you are not able to simple add 4 Vero29's to your current lights and drive them in parallel on your Area51's drivers. Thats one of the reasons I go strictly DIY.. much easier to adapt new stuff!

Trying to find anyone who sells it. I thought I saw a place at $90.

I wonder if it would work in an umbrella/parabolic fixture with vertical bulb pointing down. I talked to a commercial guy once and he liked that set up and said it ran much cooler than the bulb being horizontal.

I am thinking 1 one QB board kit $149 in the middle plus these 6 Vero 29s for $440 on the outside as a fixture. About $600 or 4 or 5 QB boards.

I would order Quantumboards only, S6-AZ bin if available + a HLG-480H-C3500B to drive all 5 boards in parallel(700mA each). This way you drive them really efficient(55%+), whole built ~400w+
4 QB's, 2 in series/2 strings parallel, same driver but 2100mA = ~450w net, (1050mA each QB, 52% eff.)
6 QB's, 3 in Series/2 strings in parallel, same driver but 1400mA = ~465w net, (700mA each QB, 55% eff.)
These calculations are for the 108v version, you can also take 54v version for more driver options or a HLG-600(or 2 HLG-320) to beat a "DE"1000...

BTW, two of these tripple Vero29 kit's driven at 2,1A would max out at ~950μMols/m² (calculated with ~50% eff., 220w net. per kit, 220PARw total).
For 1200μMol's you need at least two "quad-kits" with HLG-320's...

I am going to email Hydrobuilder web retailer.l They have a Ushio that I think is that newer type. They also have a newer Solistek sodium (flower) with UVA UVB and UVC but those scare me. You really cannot be in the room.

The HLG-600-54 is about $169. It seems like spending a few bucks for more this bigger drive will save money. So 4 QBs cna match or beat a SE.

To beat DE - I need 6 QBs? Thanks.

Nope,
you can also beat them with 4 boards but you need to drive them harder as 6 so a bit less efficient.
