Panda Film 220μm | Dual-Layer Reflective & Light-Blocking Hydroponic Grow Room Sheeting

Light management is one of the most overlooked variables in indoor growing. A grow room lined with bare walls, concrete, or dark surfaces absorbs a significant portion of the light your fixtures produce before it ever reaches the canopy. Panda Film 220μm recovers that lost light and puts it back to work. The white reflective side bounces up to 90% of usable light back into the grow space, increasing photosynthetic efficiency across the entire canopy without adding a single watt of electricity. The black side does the opposite, blocking external light completely to maintain strict photoperiod control and prevent the light contamination that disrupts flowering cycles and stresses plants.

At 220 microns, this is heavy-duty industrial-grade sheeting built for permanent and semi-permanent grow room installations. Thicker than standard poly film, it resists tearing during installation, handles repeated use across multiple grow cycles, and provides a waterproof, vapour-resistant barrier that protects walls and floors from moisture and nutrient solution. Whether you're lining a purpose-built grow room, partitioning a section of a warehouse, or upgrading an existing space, Panda Film 220μm is the professional standard for indoor hydroponic light control in Australia.

How It Works

Install with the white side facing inward toward your plants and light source. The white polyethylene surface diffuses and reflects light evenly across the grow space, eliminating the hot spots and dark zones that cause uneven canopy development. The black outer layer absorbs any light that passes through from outside, preventing light leaks from disrupting your photoperiod schedule. Together, the two layers create a controlled light environment that maximises the output of your grow lights and maintains the precise dark periods that flowering plants require.

Key Benefits

• Reflects up to 90% of usable light back into the canopy. White reflective surface significantly improves light distribution and photosynthetic efficiency, increasing the effective output of your existing grow lights without additional energy cost.
• Black layer blocks all external light penetration. Prevents light leaks that disrupt photoperiod schedules, cause stress responses, and interfere with flowering cycles in light-sensitive crops.
• Heavy-duty 220 micron construction. Substantially thicker than standard poly sheeting, providing superior tear resistance during installation and long-term durability across multiple grow cycles.
• Waterproof and vapour-resistant barrier. Protects walls, floors, and structural surfaces from moisture, condensation, and nutrient solution splashback in hydroponic grow environments.
• Suitable for walls, floors, ceilings, and partitions. Versatile installation across all grow room surfaces and configurations, including room dividers and light-proof partitions between grow and veg spaces.
• Improves grow room hygiene and cleanliness. Smooth white surface is easy to wipe down between cycles, reducing the buildup of dust, algae, and organic residue on grow room surfaces.
• Reusable across multiple grow cycles. Heavy-duty construction allows careful removal and reinstallation, reducing material costs in permanent grow room setups.
