What is the general hanging height in flower?

If I started seeds under it and had it 7 ft away would it be too much? (My kWh cost is around 10 cents so a month of veg under hid won't kill me money wise. (And I can get it cheaper than an hps system here smh)

I'm super new to cmh and double ended fixtures in general but it looks like I can get a good deal on them atm.

Any other info you think I should consider would be appreciated.

I had my up around that height and it was far too much until they got enough leaves to make use of the sheer power that thing pumps out.
 
i'm chiming in because im in the learning stages of lights too, should I go with cmh,or hps fixtures? so the way im understanding it is I would need a 315 cmh to start veg and then switch to a 630 to flower?
 
A 315 will flower a 3x3 great, veg a 4x4. And a 630 cmh is a 4x4(mostly this)/5x5 flower area.

Cmh is more efficient than hps and I like the spectrum. Hps costs more around here with decent parts and an ac.

To note my 8x8 room is flooded with stupid light using a de 630. In those smaller spaces a 315 or get two 315’s so you can get more if and only if you think you need it. These cmh lights are pretty good.
