1mx2m · 125 µm · ≈ 80% reflection · Light-proof black side
In an indoor garden, every photon you waste is yield you lose. This double-sided 125-micron film turns any wall, shelf or cupboard into a reflective grow surface: the white side bounces around 80% of your grow light back onto the canopy, while the fully opaque black side keeps your space 100% light-tight. A simple, tough and affordable accessory, selected by the BloomLED team to get the most from your LED grow lights through both veg and flower.

The white side spreads your lamp's output evenly across the grow area, reducing shaded spots and evening out PPFD so edge plants grow as strongly as those under the centre of the light.
The black side blocks 100% of light. Perfect for protecting the dark period during flowering, splitting one space into separate veg and bloom areas, or blacking out a window in seconds.
Light and flexible, the film cuts cleanly with scissors or a knife and goes up in minutes with tape or staples. It also doubles as a waterproof liner for floors and potting benches.
Always point the white side towards your plants and grow light — that's the side reflecting around 80% of the light. The opaque black side faces outwards to stop any light leaking in or out.
Is this film suitable for small grow spaces?Yes — the 1mx2m format is ideal for lining a cupboard, a seedling shelf or finishing off a grow tent. For bigger rooms, BloomLED also stocks 10-metre Mylar reflective rolls.
At just €3.90, this is one of the cheapest upgrades in indoor growing: more light on your plants without drawing a single extra watt.
