Plz help me configure vero29SE cobs for 5x5 spacing

Hi all,

Have read many threads on here without ever making any posts, I've only just completed my first grow and In planning stage of second while I wait for my thirty odd seeds from Seedsman.

I've hoping one of the more experienced ppl could spare a few min to help clarify something for me about the vero29s SE.

I just finished up in a 4x4 and am looking to buy a 10x10 but only utilising half of it on this next grow.

So 5x5 space, I'm thinking 16 cobs and I just ran the figures at 1050ma and correct me if I'm wrong but that's 36.4 volts per cob if ran on the HLG-240h-c1050b (6 cobs running on 2 of these and remaining 4 on suitable driver. That's 38.2 watts x 16: 611 watts in total.
I grasp ppfd is the metric I should work with but I don't know how to convert figures to umols-s-2 (if correct)
Can someone help me determine how many veros29 to run in this space and at what Ma to get a consistent 750-800( seems to be desired range for flower without co2)
I prefer to keep the efficiency high...I can handle few bucks on more cobs if this is the key. Wanting to keep watts down as I'm working towards furthering my skills and increasing the size of my garden to 10x10 so watts too high will make me paranoid about electricity when I get to my end game garden with a veg tent running too.

I've seen many sharp ppl respond to questions like this like it's back of their hand....any expert advice would be greatly appreciated. Sorry for rambling :/

Peace
 
Cheers mate, no still in investigation mode just germinating seeds as we speak and have lighting to sufficiently veg them.

What chip said
You will be useing 25 square feet (5x5)
Square feet (25) times min amount led wattage (33) equals 825 watts
So you’ll need about 800 watts ( give or take from wall) to start I do believe
