Undecisive on what to do? Please help.

I only have a few feet wide and length for something that's going to be a perpetual grow. I was thinking of a big flower chamber on top of a small vegetative chamber. I wanted to use coco and perlite but have recently came across DWC and was thinking maybe a 8 plant DWC reservoir. There would be in another 8 plant DWC reservoir for the vegetative chamber. The reason for 8 plants is one plant will be one week old from each other so I can have a Perpetual garden and harvest every week.

You posted this twice. What is your question?

Yea my stupid phone doesn't want to delete the other post. Basically I was asking what would be a good design for a 8 plant veg and flower chamber stacked. Can't be too big.
