This. ^^My advice is get at least one small grow under your belt so you have success, then expand a bit each grow.
Plus, how are you going to identify your keeper female if you don't flower them all and see which end product you like best? Good growth structure of the plant is only one factor. Others are quality of harvest, quantity of harvest, smell, taste, effect, etc.
You won't know any of that without following them all through to the end.
I say follow Nunya's advice and learn what you need to know before blowing through all your gear before you really have a decent handle on what you're doing.
