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 in the flower chamber. 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.
