Total Blackout Sheeting

Kill light leaks and keep the dark cycle truly dark

Total Blackout Sheeting is a heavy-duty, 100% light-proof polyethylene sheeting that blocks unwanted light while protecting indoor growing spaces. A black side stops light penetration and a white reflective side maximises light efficiency, making it ideal for lining grow rooms, partitioning cultivation areas and covering windows or doors across hydroponics, indoor growing and greenhouse setups.

Key Benefits

• 100% light-proof construction for complete blackout
• Black side prevents light leaks and outside light intrusion
• White reflective side bounces light back towards plants to improve efficiency
• Uninterrupted dark periods maintained during flowering
• Durable, tear-resistant and waterproof material
• Easy to cut and install to suit different spaces
• Doubles as floor or wall protection against moisture and spills

Light leaks stressing your plants at lights-off?

Light leaks during the dark cycle interrupt flowering and cause plant stress, delayed bloom development or, in some crops, hermaphroditism. Total Blackout Sheeting forms an effective light barrier for uninterrupted darkness through bloom, while the reflective surface improves light distribution and the waterproof film shields walls and floors from moisture and nutrient spills.

How to Use

1. Measure the area to be covered.
2. Cut to size with sharp scissors or a utility knife.
3. Install with the white side facing the plants and the black side facing outwards.
4. Secure with suitable tape, clips or fixings.
5. Seal all joins and edges with heavy-duty tape to eliminate light leaks.
6. Inspect regularly for tears or gaps and repair promptly to maintain complete blackout.
