VIVOSUN 6 Mil Mylar Film Roll 4 x 25 ft — Heavy-Duty Diamond Reflective Film for Grow Tents, 92–97% Reflectivity

VIVOSUN's 6 mil diamond mylar film is a heavy-duty, highly reflective PET roll (4 ft × 25 ft) designed to boost light distribution and stabilize temperature inside grow tents, greenhouses, and indoor grow rooms.

Use this diamond-textured reflective foil to maximize usable light from any indoor horticulture setup without changing your fixtures. The 6 mil thickness balances puncture resistance and flexibility; an aluminum-coated surface combined with a patterned texture returns more light to plants while resisting humidity and routine cleaning. The roll ships with a sealed cover to keep the film clean in storage and can be cut to fit any wall, ceiling, or propagation box.

How does the diamond texture improve light for plants?

The raised diamond pattern scatters and redirects light, reducing hotspots and dark corners so plants receive a more even irradiance. That improved diffusion lets lower canopy leaves get useful photons and helps avoid burned leaf tips under strong lamps.

• Reflectivity rated at about 92%–97% due to diamond surface and aluminum coating
• Light scattering reduces glare and concentrated hot spots
• Helps distribute light to lower foliage for more uniform growth

Is this film durable and easy to maintain?

The mylar is a 6 mil thick PET laminate engineered for tear resistance and thermal stability, so it stands up to installation handling and humid indoor conditions. If it accumulates dust or soil, a damp cloth is usually enough to restore reflectivity without damaging the surface.

• 6 mil thickness resists punctures yet remains easy to cut and shape
• Macromolecular PET construction resists tearing and humidity
• Wipe-clean surface and included sealing cover for storage protection

Will this film fit my space and how do I install it?

The roll measures 4 feet wide by 25 feet long, and it can be trimmed with scissors to suit walls, ceilings, tent frames, or small boxes. Install with adhesive tape, clips, or staples depending on the mounting surface; patch seams for continuous reflection where needed.

• Cut-to-fit design for custom installations in tents, greenhouses, and rooms
• Compatible with common mounting methods: tape, clips, adhesives, or staples
• Sealable bottom cover keeps the unused roll clean during storage

What practical benefits can I expect for indoor gardening?

By returning a large percentage of emitted light back to the canopy, the film increases overall light-use efficiency without adding power draw. It also helps moderate microclimate by reflecting radiative heat, making it easier to control temperatures in compact grow spaces.

• Greater light-use efficiency from existing fixtures
• Improved uniformity helps reduce stretched or uneven growth
• Reflects radiative heat to assist temperature management in small spaces

Who is this for? Growers, hobbyists, and professional cultivators who want an affordable, reusable way to improve light distribution and protect interior surfaces will find this VIVOSUN 4×25 ft, 6 mil diamond mylar roll useful. It suits people fitting tents, lining shelves, building propagation boxes, or upgrading a grow room’s reflectivity—anyone who needs a durable, cleanable reflective surface that can be trimmed to size.
