First timer - Seeking veteran opinions

First off..thanks for you're time..

I have an 8'D x 10'W x8H basement I'm planning on turning out..my questions are..

1) Being able to devote the entire area to the grow; what would be the best method as far as yield is concerned. I would need to house the clones and mothers in the same area. However, I have read that mothers can be kept fairly small with regular pruning.

2) How many lumens? And I understand that wattage is not really a concern as far as getting busted goes so long as it's not outrageous; but whereabouts is that line?

3) I've been looking into going the SOG bubbleponics route but what is the MAXIMUM amount of plants I could fit into say a 6' square area if I was lollipoppin em and using say..two weeks max veg time? I really want to cram these bastards in there but i understand that can be counter-productive. I just want to stress the word.."MAXIMUM"

Thanks a lot guys..hope to hear from you soon
