TotalGrow Mezzo 100W Light Bar Applications

The TotalGrow Mezzo 100W Light Bar is designed for maximum versatility across growing environments. In greenhouses, its slim profile creates minimal shadowing when mounted as supplemental top-lighting. For indoor applications, the fixture can be used as primary lighting for smaller spaces or seedling areas. The Mezzo truly excels in side-lighting and intercanopy applications, where its narrow form factor allows placement directly within plant canopies to deliver light to lower leaves and inner foliage that typically receive less illumination. This flexibility makes the Mezzo an ideal solution for addressing specific lighting challenges or enhancing light uniformity throughout your growing operation.
