Grass Slab

TypeSolid block

The Grass Slab is a slab added by Better With Mods. Grass Slabs are grown out of Dirt Slabs (surrounded by Grass) and can, in turn, turn regular Dirt Blocks into normal Grass Blocks. Grass Slabs can also be right-clicked with a Shovel to make Path Slabs.

Grass Slabs can not be placed in the top half of a block, however, placing a Grass Slab on top of another will turn them both into a single Dirt block.
