Permaflect Reflective Fabric – 25′ x 54″

The Permaflect Reflective Fabric by Hydrofarm is a heavy-duty, mesh-backed reflective sheeting designed for grow rooms, tents, and cultivation spaces. Unlike standard mylar films that degrade and crinkle over time, Permaflect can be wiped clean, maintaining consistent reflectivity across its surface. The 25-foot roll is 54 inches wide — 6 inches wider than most competing rolls — giving you more usable coverage per linear foot.

Why Choose Permaflect Reflective Fabric

Standard mylar film is inexpensive but fragile. It tears easily, develops wrinkles and creases that create light hot spots, and collects dust and debris with no practical way to clean it. Permaflect addresses these limitations with a more durable construction and a surface that can be wiped down between cycles.

• Wipe-clean surface: Unlike bare mylar, Permaflect can be cleaned with a damp cloth. This matters for multi-cycle grow rooms where maintaining consistent reflectivity is important and residue buildup is routine.
• Mesh-backed construction: The woven mesh backing reinforces the material against tearing and helps it hang flat without bunching. Flat, even surfaces reflect light more uniformly than wrinkled film.
• Diffuse reflection, no hot spots: The mesh structure increases light diffusion across the reflective surface, reducing concentrated hot spots that can stress plants positioned close to walls.
• Oversized roll width: At 54 inches wide, this roll is 6 inches wider than most competing reflective films. Fewer seams mean a more continuous reflective surface and less installation time cutting and joining narrower strips.
• Multiple installation formats: The fabric is flexible enough to use as a wall liner, lay flat as a floor covering, or hang as a room divider to partition off sections of a larger grow space.

Best Uses for Permaflect Reflective Fabric

Permaflect is suited for growers who need reliable, reusable reflective coverage across a range of grow-room configurations. The wide roll format and durable construction make it practical for permanent or semi-permanent installations rather than single-use setups.

• Grow room wall lining: Cut to height and attach to walls to redirect light back toward the canopy. The 54-inch width covers standard 8-foot walls in two strips with minimal overlap, keeping seam count low.
• Floor coverage: Lay sections flat under growing trays or tables to capture downward light scatter and reflect it upward through the lower canopy. Particularly useful under raised bench systems.
• Room partitioning: Hang sections from overhead supports to divide a larger space into separate zones — useful for keeping vegetative and flowering areas isolated or for creating a dedicated propagation corner. If you are setting up a full propagation zone, a propagation system like the Super Sprouter Premium Heated Propagation Kit with T5 Light pairs well with reflective wall coverage to maximize light delivery to young cuttings.
• Supplementing fixed lighting systems: In spaces lit by T5 or LED fixtures, reflective walls help distribute light more evenly to lower and peripheral plant sites. Growers using a T5 Designer 4ft 4-Tube Fixture with Bulbs often line adjacent walls to extend usable light coverage beyond the direct footprint.
• Multi-cycle commercial spaces: The wipe-clean surface makes Permaflect a practical choice for rooms that are cleaned and reset between production cycles, where disposable film would need replacement but a durable fabric liner can be wiped down and reused.

Usage Guidelines

Permaflect is passive reflective material — there is no powered component, so installation focus is on achieving a flat, seam-minimized surface that reflects light as uniformly as possible.

• Cutting: Use scissors or a utility knife with a straightedge. The mesh backing holds cut edges without fraying under normal use.
• Attachment: Secure to walls using staples, double-sided tape rated for the substrate, or hook-and-loop strips for removable installations. Avoid over-tensioning at attachment points, which can cause puckering in the center of the panel.
• Seaming: Where panels meet, overlap edges by 2–3 inches and tape the seam on the back side to prevent gaps. A continuous reflective surface is more effective than multiple small panels with visible gaps between them.
• Cleaning: Wipe with a damp, lint-free cloth to remove dust and residue. Allow to dry fully before the next light cycle. Avoid abrasive cleaning materials that could scratch the reflective surface.
• Storage: Roll rather than fold when storing unused lengths. Folding can create creases that do not fully flatten out, which reduces reflective uniformity in those areas.
