Now you know that the Gminor pentatonic scale is 5 notes (G-Bb-C-D-F), and the G blues scale is 6 notes (G-Bb-C-Db-D-F). You can play those 5 or 6 notes ANYWHERE on the fretboard, in ANY combination, ( "musicality" will set limits ). Use your imagination/creativity. It's OK to learn the rudiments of scales in "the box" - but don't let it limit you. Look at the notes in the G blues scale from frets 1 thru 12 - lots of possibilities there ! Also, notice where the "box" locations are, anchored on the 3rd fret.
