Continuous grow would be veg, flower, cloning, mother. 4 seperate rooms in theory, all you need to distinguish with the rooms is the lighting cycles.
Vegging cycles vary from 24/0, 20/4, 18/6, 16/8, 12/5.5/1/5.5 lights on/off.
Flowering cycles are usually 12/12 others use 13/11, 11/13, 10/14
Is space is an issue then I would go with LED's, depending on your budget you can get what you like. Results vary from person to person and site to site.
I like Kessil's and Blackstar's have been doing pretty good too. I only have ever used CFL's so I don't know about other lighting.
Training is the most fun, you could start out main-lining, topping, lst, scrog. Again it's a personal preference. Main-lining is a hybrid form I guess. That
tops the plant then bends it down lst fashion to create a hub of equal sized shoots over a period of time. LST is simply pinning shoots down so the branch
evens out over itself and starts growing up the same length. Scrog is putting a screen over and lst that way. More or less. Anything else is up to you.
Also for odor control and airflow look into inline or can fans and carbon filters. I don't use these for space reasons currently.
