Pentahex Barriers (1191)

Divide the grid into pentahexes such that every cell in the grid is part of exactly one pentahex. You cannot have more than one pentahex of the same shape (rotations and reflections of a pentahex count as the same shape). Some rows are labeled with a number; the number represents the number of edges in that row that separate two different pentahexes. Some of those edges may be drawn for you.
