i'm gonna have to just repeat what LIP did, go search the forum. the questions you just asked are all matter of opinion and experience, there is no "better" way. there are plenty of threads with examples of how to build a clone bubbler.... http://boards.cannabis.com/showthread.php?t=23400 here's one by Zandor, and i know for a fact that if you just search the title of a thread in the Cultivation section with the word "cloning" or "clone" you will find plenty of info. you also don't have to follow someone elses method the the T, just as long as you get the basic idea and method.
