Lighting designers and event coordinators looking for a cost-effective low-lying fog package will appreciate this B&H Kit that combines four 1-gallon jugs of the CHAUVET DJ LLG Low-Lying Fog Formula, which is specifically designed for the Cumulus and Cloud 9 fog machines to create a thick cloud that hugs the floor without the need for dry ice. The unscented, nontoxic, and nonflammable fluid will not stain or leave any residue.
