Thinking about growing in a 6'x6' closet....

I'm thinking about growing in my closet. I will have a 2'x3'x6' for veg/clones and 6'x6'x8' for the flowering area. I'm thinking about growing in pvc tubes through a drip system in a "V" shape for best exposure to the light.

My questions are these. What are your thoughts on this type of setup? How many plants and how many lights should I use? I already have a 1000watt HPS/MH system currently. How big should the PVC be? How big should the net baskets be? How far apart should I space them? How much could I yeild from a room this size with clones? Any and all thoughts are welcome.

Thanks,
