Yup...Sorry, answered before my 3rd cup of coffee...

Without knowing:
A) what equipment you have. (lights for veg and flower)
B) how you want to grow (hydro or soil, closet or garage...)
C) your experience with growing
D) what your budget is...
...there is no way to accurately answer.

If just begining...a timer, a few 2x4's and some chains to hang your lights in a walk-in closet, is the cheapest way, and gets a bit more complicated from there.

Personally, I would start cheap, and develop a workable plan from your first couple of grows. That way you will know better what to look for in a 'complete system'.
Some folks don't need beautiful trays and racks, carbon scrubbers, CO2 systems, moon lights...Money is so easily wasted on unnecessary crap, just 'cuz you've read someone else has it. (kidding about the moon lights)

As a hydro store owner told me...it's difficult to expand your growspace, with a pre-built system.

HTH...Rusty

edit: are you planning on getting seperate systems for vegging and flower, or just use one space for both?
