Grodan Improved Gro-SlabsGrodan Improved Gro-Slabs are multi-plant stone wool slabs with an optimized fiber structure and an advanced wetting agent that holds water content even from end to end. Vertical fiber orientation drains freely and re-saturates quickly after a dry-back, so a steering change lands the same way across every slab in the room.This is the plain slab without pre-cut holes, giving you free placement of blocks along the slab.
