Gorilla Black/White Poly Sheeting Roll – for Grow Rooms

Full-length reflective lining for a grow room wall, floor or DIY tent build

The Gorilla Black/White Poly Sheeting Roll gives you a full 2m x 100m run of black-and-white polythene film, black on one side and white on the other, for lining grow room walls and floors or building a custom enclosure. The white face reflects light back towards the canopy while the black face blocks light from passing through, so you get a light-tight, wipeable surface in a single material.

Key Benefits

• Full 100m roll covers a whole room or several builds from one length, with no repeated ordering.
• Black one side, white the other — white reflects light back onto the canopy, black blocks light leaks.
• Wipeable, waterproof surface is easy to keep clean and resists mould better than bare plasterboard or wood.
• Two thicknesses available to suit a permanent room lining or a lighter-duty temporary build.
• Cut to length for walls, floors, ceilings or a fully custom-built grow space.

Bare walls and unsealed floors soak up light that should be reaching the canopy and make a grow room much harder to keep clean between cycles. Lining the space white-side-in reflects stray light back onto the plants instead of losing it, while the black-side-out option keeps a room fully light-sealed against outside light bleeding in or your own light cycle bleeding out.

How to Use

• Measure first: plan your cuts against the wall, floor or frame you are lining before unrolling.
• Choose your face: white-side-in for maximum reflected light, black-side-out where light-sealing matters more.
• Fix in place: staple, tape or clip the sheeting to a frame or wall, overlapping joins to avoid light gaps.
• Seal joins: tape seams and edges for a fully light-tight, wipeable finish.
