Permaflect Reflective Fabric – 100′ x 54″

Permaflect Reflective Fabric by Hydrofarm is a 100-foot by 54-inch roll of heavy-duty reflective material designed for grow room wall and floor coverage. Unlike standard mylar, its wipeable surface maintains long-term reflectivity without degrading, and an internal mesh construction diffuses light evenly across the canopy to prevent hot spots.

Why Choose Permaflect Reflective Fabric

Permaflect addresses practical problems that arise with standard mylar in active grow environments. Here is what sets it apart based on the manufacturer’s product data:

• Wipeable surface for lasting reflectivity. Traditional mylar becomes clouded and loses reflectivity over time as nutrient solution, moisture, and dust accumulate on its surface. Permaflect’s surface can be wiped clean, preserving consistent reflectivity through repeated grow cycles.
• Wider than standard rolls. At 54 inches wide, this roll is 6 inches wider than most competing reflective fabric products. That extra width reduces the number of seams needed to cover a wall, which in turn reduces light-loss gaps and simplifies installation on taller side walls.
• Mesh construction diffuses light and eliminates hot spots. The internal mesh backing increases light diffusion, spreading photon flux more evenly across the canopy rather than concentrating it in high-intensity points. This is particularly valuable in smaller rooms where fixture proximity to plants is unavoidable.
• Reinforced for durability. The reinforced construction holds up to repeated handling, trimming, and repositioning without tearing at edges — a common failure point for non-reinforced reflective films.
• Multiple use configurations. The fabric works as a wall liner, floor covering, or room divider, giving growers flexibility to configure their space without purchasing separate materials for each surface type.

Best Uses for Permaflect Reflective Fabric

Permaflect is suited to any enclosed growing environment where maximizing light return to the plant canopy matters. The following are the primary use cases for this product:

• Wall lining for grow rooms and tents. Attach the fabric to the interior walls of a grow room or tent to reflect light that would otherwise be absorbed by bare surfaces. The 54-inch width accommodates most standard wall heights without requiring a horizontal seam.
• Floor covering beneath plant trays. Laying Permaflect on the floor beneath raised benches or tray systems reflects upward-escaping light back toward the lower canopy, improving light uniformity for multi-tier setups.
• Room dividers to isolate light environments. Growers running separate vegetative and flowering zones in the same space can use the fabric as a light-blocking and light-reflective room divider, directing photons inward rather than losing them across zones.
• Supplemental coverage alongside grow lights. When paired with a fixture such as the T5 Designer 4ft 4-Tube Fixture, reflective wall coverage increases effective light delivery to the canopy without increasing wattage.
• Propagation and seedling areas. Low-intensity propagation setups benefit from reflective liners because seedlings and cuttings are sensitive; maximizing the yield from gentle lighting reduces the need to increase intensity and risk stress. If you run a propagation space with a Super Sprouter Premium Heated Propagation Kit, lining the surrounding walls with Permaflect will help keep light levels consistent.
• Large-scale commercial rooms. At 100 feet per roll, this product is sized for commercial and large-scale hobbyist installations where single-roll coverage of long wall runs is practical.
