Left or Right? - Truss Rod

[Two hands31]

Simple question, I know, but, on a Strat, which way should I turn the truss rod and how much if it's bowed a bit too much (i.e. *strings higher @ 12th fret than 1st fret)?

if up-bowed: left
if relief: right

it needs just a quarter turn to see a little changing on the neck. anyway, not more than a quarter turn at a time.
