VIVOSUN Black and White Panda Film, 10′ x 100′
The VIVOSUN 10′ x 100′ Panda Film uses a black-and-white dual-sided design to block light and reflect heat back to plants. The black side creates a dark space to prevent unwanted light penetration, while the white side offers over 90% reflectivity, helping to maximize interior light efficiency. Constructed from 5.5 mil virgin poly material, this film is designed for durability in repeated use and weather exposure, supporting winter warmth without heavy light leakage.
Features include a reflective cover that keeps roots warm and promotes even light distribution, along with a tough, long-lasting build intended for frequent handling and outdoor deployment. This option is suitable for larger greenhouses or scenes where extended blackout periods are required, and its size makes it a practical choice for growers who run broader canopies.
VIVOSUN Black and White Panda Film, 10’ x 50’
This 10′ by 50′ version shares the same dual-side design and 5.5 mil thickness as the longer roll, offering a compact but effective blackout solution. The black exterior minimizes ambient light intrusion, while the white interior reflects light for improved canopy illumination. The combination supports stable night-time temperatures and can help minimize hot spots on walls and floors by distributing light more evenly.
Farm Plastic Supply – Panda Film Light Deprivation Greenhouse Cover (24′ x 10′)
This Panda Film from Farm Plastic Supply emphasizes longevity with a UV-inhibitor designed to withstand sun exposure. The 6 mil thickness provides added durability against tearing and daily wear, making it a strong choice for larger installations that require reliable blackout performance while resisting environmental degradation. The white side reflects exterior light, while the black side maintains a dark internal environment, helping to create a stable microclimate inside the greenhouse.
AC Infinity Black and White Panda Film (10′ x 100′)
AC Infinity’s panda film blends light control with practical durability. The film sheet increases reflectivity, helping to amplify the available lighting while also providing protective layers to manage spills or moisture. Its white side offers about 90% reflectivity, which helps reduce hotspots and improve light distribution across walls and floors. The product is designed to withstand prolonged sun exposure thanks to sturdy, tear-resistant polymer construction, making it suitable for year-round greenhouse use.
iPower Black and White Panda Film (10 x 10 ft)
The iPower panda film is designed for small to mid-size grow rooms, offering a balance of durability and light control. Its 5.5 mil thickness, combined with a white side that reflects over 90% of light, helps distribute light uniformly to minimize hot spots while keeping the dark side effective at blocking unwanted light leakage. The tape-and-foil-like resilience translates to good performance under seasonal shifts and daily handling during setup or removal.
Farm Plastic Supply – Panda Film Light Deprivation Greenhouse Cover (6′ x 25′)
This six-foot-wide roll from Farm Plastic Supply offers a compact blackout solution with 6 mil thickness. The white exterior reflects light outward, while the black interior helps maintain a dark environment inside the greenhouse. The product is designed for durability and practical use in tighter spaces, accommodating smaller or modular greenhouse configurations without compromising light control or longevity.
Buying Guide: Key Purchase Considerations
- Light Control: Look for a true blackout design with a durable black exterior and a high-reflectivity white inner layer. Ensure the white side provides 80–90%+ reflectivity to maximize light efficiency.
- Thickness and Durability: A thickness of 5.5–6 mil balances tear resistance with flexibility. Thicker films generally offer longer lifespans, especially in windy or sun-exposed environments.
- UV Resistance: UV inhibitors extend the life of the film when exposed to sun, reducing degradation from prolonged exposure and helping maintain structural integrity through seasons.
- Size and Fit: Choose a size that fits your greenhouse dimensions with some overlap for secure mounting. Custom or wider rolls are helpful for larger structures, while compact sizes suit smaller grow rooms.
- Reflectivity and Heat Management: Higher white-side reflectivity improves internal lighting efficiency and helps distribute heat more evenly, reducing hot spots and temperature gradients.
- Installation and Handling: Consider ease of installation, ease of removal for seasonal changes, and compatibility with existing framing or shading systems. Durable grommets or edge reinforced areas are a plus.
- Durability vs. Cost: Compare both initial cost and expected lifespan. A slightly higher upfront investment in a thicker, UV-resistant film can reduce replacement frequency and maintenance over time.
- Environmental Conditions: If you experience high heat, strong sunlight, or frequent wind, prioritize films with robust tear resistance and UV stability to prevent ripping or warping.
- Multi-season Performance: Some panda films are designed to perform well in winter warmth and summer shading, supporting plant growth cycles across the year.
Choosing the right blackout tarp involves balancing size, durability, light control, and cost. Panda-film options are widely favored for greenhouse environments because their dual-sided design helps manage both light exclusion and reflectivity. When selecting among these five products, consider your greenhouse dimensions, climate patterns, and whether you need a longer roll for a larger canopy or a compact option for smaller grow rooms.
