Yes what your talking about is a SCROG. Like the others say but !

Sea of Green is not just a harvest every three or four months. It can only be done inside. It is a harvest every month or even two weeks. Your room is like a conveyor belt. As a harvest is complete new ones already vegged must take their place. This can be many small ones or a few big ones depending on how much you put into it.

In a Sea of Green the flower room is just like any other. ALL the MAGIC happens in the mother and vegg room. It is much work. Not for the stoner that can't keep up, they soon fail.
