{"product_id":"panda-film-220um-hydroponic-grow-liner","title":"Panda Film 220μm | Dual-Layer Reflective \u0026 Light-Blocking Hydroponic Grow Room Sheeting","description":"\u003cp\u003eLight 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.\u003c\/p\u003e\u003cp\u003eAt 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.\u003c\/p\u003e\u003ch2\u003eHow It Works\u003c\/h2\u003e\u003cp\u003eInstall 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.\u003c\/p\u003e\u003ch2\u003eKey Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReflects up to 90% of usable light back into the canopy.\u003c\/strong\u003e White reflective surface significantly improves light distribution and photosynthetic efficiency, increasing the effective output of your existing grow lights without additional energy cost.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack layer blocks all external light penetration.\u003c\/strong\u003e Prevents light leaks that disrupt photoperiod schedules, cause stress responses, and interfere with flowering cycles in light-sensitive crops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-duty 220 micron construction.\u003c\/strong\u003e Substantially thicker than standard poly sheeting, providing superior tear resistance during installation and long-term durability across multiple grow cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof and vapour-resistant barrier.\u003c\/strong\u003e Protects walls, floors, and structural surfaces from moisture, condensation, and nutrient solution splashback in hydroponic grow environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for walls, floors, ceilings, and partitions.\u003c\/strong\u003e Versatile installation across all grow room surfaces and configurations, including room dividers and light-proof partitions between grow and veg spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproves grow room hygiene and cleanliness.\u003c\/strong\u003e Smooth white surface is easy to wipe down between cycles, reducing the buildup of dust, algae, and organic residue on grow room surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReusable across multiple grow cycles.\u003c\/strong\u003e Heavy-duty construction allows careful removal and reinstallation, reducing material costs in permanent grow room setups.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHydroponic indoor grow room wall and ceiling lining\u003c\/li\u003e\n\u003cli\u003eGrow room floor protection and moisture barrier\u003c\/li\u003e\n\u003cli\u003eLight-proof partitions between grow and veg spaces\u003c\/li\u003e\n\u003cli\u003eGreenhouse light control and insulation lining\u003c\/li\u003e\n\u003cli\u003eCommercial controlled environment agriculture installations\u003c\/li\u003e\n\u003cli\u003eGrow tent interior upgrades for improved light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness.\u003c\/strong\u003e 220 micron (μm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial.\u003c\/strong\u003e Dual-layer polyethylene film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour.\u003c\/strong\u003e White (reflective inner) \/ Black (light-blocking outer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight Reflectivity.\u003c\/strong\u003e Up to 90% (white side)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction.\u003c\/strong\u003e Light reflection, light blocking, vapour barrier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication.\u003c\/strong\u003e Hydroponics, indoor grow rooms, greenhouse lining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation.\u003c\/strong\u003e Walls, floors, ceilings, partitions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReusability.\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Bought Together\u003c\/h2\u003e\u003cp\u003ePanda Film works as part of a complete grow room build.
