There are a lot of variables to know about.

Some are discovered by trial and error, as I myself have found out, and some by reading, observing and absorbing as much as possible from everyone else out there who has been at this for awhile. I'm not a "green thumb" by any stretch of the imagination, not even close, but from what I have seen personally, it really is worth the effort to learn this artform and apply it . . . which is what has brought me to hydro forums, like this one.
