all i do is dispensary clones, just too easy not to i guess...
you can definitely start them in a deep water culture/bubbleponics system. you can use an active system like the stealth hydro kit or just do passive dwc without water circulation - its a fairly superficial difference once you get the hang of things.
with all due respect, sounds like you need to do some more reading before you do any potentially wasteful spending - i read a lot and still wasted money on crap that didn't work for me (and not everything works for everyone).
buy clones in rockwool or rapid rooters if you plan on putting them into any hydro application. i'd only buy soil-rooted clones for growing in soil. also, if you have to drive far to buy them, have a humidity dome ready & waiting at home to put them in till they recover.
