Anti-detection Reflective Plastic is a technical sheet designed for indoor cultivation that combines light reflection, thermal barrier, and total light blocking. Ideal for lining grow rooms and cabinets, it improves lumen utilization and adds an extra layer of discretion in domestic or professional installations.
Features of Growlux Anti-detection Reflective Plastic:
- Full roll of 1.20 x - 88% light reflection
- 94% thermal reflection
- 100% moisture barrier
- 100% light proof
- Light and heat reflection certificate issued by TNO (official Dutch research institute).
- Highly tear-resistant product
- Extra coating

The Anti-Detection Reflective Plastic stands out for its multilayer construction that simultaneously acts as a mirror for useful light and as a shield against moisture and light leaks. In a wide roll format (technical width of 1.20–1.22 m and length of 60 m approx.), it is perfect for covering perimeters without unnecessary cuts, achieving smooth surfaces that maximize reflection.
The reflective side delivers up to 88% light reflection, while the internal structure offers 94% thermal reflection, reducing heat transfer to the outside.
The film is 100% lightproof and acts as a moisture barrier, preventing condensation and splashes from damaging walls. An extra coating reinforces mechanical resistance against pulling and rubbing, and there is a light and heat reflection certification issued by TNO (official Dutch institute), a top-level technical endorsement.
Installation is simple: just use double-sided tape, staples with washers, or battens to fix the sheets tight and wrinkle-free.
This combination makes the sheet an efficient, stable solution of plastic for grow rooms, compatible with prefabricated cabinets, conditioned rooms, or adapted greenhouses.
In an indoor growing environment, Anti-Detection Reflective Plastic increases usable PPFD by redirecting side and rear light to the plant canopy. The homogeneous reflection reduces shadows in the middle and lower areas, promotes compact internodes, and helps stabilize peripheral temperature. The 100% opaque condition prevents light entry during “night” and leaks during “day,” protecting photoperiods in flowering. The result is a more productive and predictable space, with less lumen waste and greater uniformity among plants.
The purpose of Anti-Detection Reflective Plastic is twofold: maximize the useful light that reaches the plants and limit thermal transfer to the outside. The sheet reflects up to 88% of incident light and blocks 94% of thermal exchange, also acting as a moisture barrier and light screen. It is a strategic option of cheap reflective plastic for covering grow rooms when seeking light performance and operational discretion.
The sheet combines with multiple indoor accessories: extractors and intractors, oscillating fans, carbon filters, fabric pots, trays, climate controllers, and automatic irrigation. Within the group of cheap accessories for indoor growing, this solution offers immediate return: more usable light without changing luminaires and extra protection of the space against moisture. Perfect for projects starting from scratch or for those who want to start growing by updating only the lining.
Before installing Anti-Detection Reflective Plastic, it is advisable to measure the perimeter of the room and multiply it by two to cover in two horizontal strips (usual example: 1.2 m + 1.2 m = 2.4 m of useful height). If the room exceeds 2.40 m, it is recommended to place the material attached to the ceiling and leave a free lower baseboard or complete with a third strip. The sheets are fixed tight and without folds with high-adhesion double-sided tape, staples with washers, or screwed battens. Occasional cleaning with a slightly damp cloth maintains reflectance and appearance. The reflective side should face the crop to redirect the light; in this way, the anti-detection property is used while increasing useful lighting.
The price of Anti-Detection Reflective Plastic offers a remarkable cost/benefit ratio: direct increase of usable light, 94% thermal reflection, 100% opacity, and moisture barrier in a single product. The long roll format reduces joints and assembly times, optimizing materials and labor.
