Made from polyester film coated with aluminium, it bounces light from your grow lamps back toward your plants instead of letting it disappear into dark corners.

If you're making a permanent professional installation, premium film is worth the extra outlay.\u003c\/p\u003e\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003eSilver mylar sheeting works across most indoor growing setups:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003cbr\u003eStart from the top of your wall, peel slowly, and use a squeegee or smooth tool to flatten as you go. The key is avoiding air bubbles and wrinkles — they create hot spots and reduce reflectivity. Velcro strips are a smart way to hang it with minimal creasing. Think window tinting, not poster hanging. Overlap seams slightly and use reflective tape to seal them properly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCovering growing spaces\u003c\/strong\u003e\u003cbr\u003eLine the walls and ceiling of your grow room, tent, or even a cupboard. Leave room around ventilation intakes and exhausts. This 5m roll covers a wall roughly 5 metres long and 1.4 metres high — ideal for small-to-medium spaces like 1m² tents or home cupboard grows.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMold and humidity\u003c\/strong\u003e\u003cbr\u003eMylar can harbour mold in high-humidity environments if moisture sits behind it. Keep your growing space well-ventilated and watch temperature and humidity levels. If condensation builds up, improve air movement. Clean mylar monthly with a soft cloth and a light 10:1 water-to-hydrogen-peroxide mix — don't scrub hard.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDurability and replacement\u003c\/strong\u003e\u003cbr\u003eAt 35 micron thickness, this mylar is lightweight and flexible but prone to punctures and tearing if handled roughly or removed repeatedly. It's best suited to setups where you won't be taking it down and putting it up constantly. Treat it as a consumable for temporary builds, not a permanent fixture.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: \u003cstrong\u003e5 metres length × 1.4 metres width (7m² coverage per roll)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaterial: \u003cstrong\u003ePolyester film (PET) with aluminium metal coating\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eThickness: \u003cstrong\u003e35 micron\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eLight reflectivity: \u003cstrong\u003eUp to 97%\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eSurface finish: \u003cstrong\u003eSilver\/glossy\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFormat: \u003cstrong\u003eContinuous roll, lightweight and flexible\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstallation: \u003cstrong\u003ePeel-and-stick adhesive or velcro mounting\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFirst-time growers building on a budget and wanting to see real results cheaply\u003c\/li\u003e\n\u003cli\u003eAnyone running temporary or seasonal grows where durability isn't critical\u003c\/li\u003e\n\u003cli\u003eGrowers with small-to-medium spaces (cupboards, small tents, shelving units) where wall coverage matters most\u003c\/li\u003e\n\u003cli\u003eDeal hunters who understand that 97% reflectivity costs the same whether the film costs £14 or £60\u003c\/li\u003e\n\u003cli\u003eGrowers testing indoor growing before investing in premium permanent setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eParticularly well suited to setups where \u003cstrong\u003ecost-per-square-metre and light efficiency matter more than long-term durability.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cp\u003eThis is genuine reflective sheeting at a price that makes proper sense. 97% reflectivity is the same number you'll see on premium films costing four times more — the difference is durability and mold resistance, not light bounce.
