Your room looks nice! It is great having a perpetual grow, with some vegging while others are flowering...BUT... it's difficult to keep one side totally dark during the times when the lights are on next door. It can be done but usually takes away some of your growing area to erect your light barrier. Ventilation is sometimes difficult if you need to pull air thru two rooms and keep humidity right. It would be a lot easier to grow and flip all of them at the same time, and it would give you a basic trial run to refine your technique over.
Obviously you have done your homework and everything looks good. I would just recommend trying a trial grow to see how your system works and any changes that you need to make are made based on experience. I know that you want to have a perpetual system, but try a single room first and see how you do. If you do great, then consider advancing your system. If you struggle, get those issues worked out before you try something much harder.
