VIVOSUN 6 Mil Mylar Film Roll 4 FT X 25 FT Diamond Film Foil Roll Highly Reflective Grow Room (25 FT)

It was delivered quickly and in great shape. The material is the perfect thickness for my grow tent. Previously I tried saving money by using Mylar blankets, those survival blankets, and they were hard as hell to work with. The Mylar blankets were too thin to staple, would tear easily, and it still let a lot of light pass through it. On the other hand, this material has little to no transparency, it staples on drywall and wood, it is tough, and it has good reflective properties. Smooth reflective materials (like Mylar blankets) tends to scatter light (especially if there are wrinkles in the material) in a disordered and inefficient way, but this material seems to be scattering light evenly and it doesn't wrinkle (as long as you do a decent job). If you are building your own grow tent than this is a great material, especially for the price.

Not sure what other people bought but this is definitely 6 mil, very heavy, nice pattern. You do have to be a bit careful, as with any plastic film. If you fold it over an object, it will crease or mark. Was concerned how to mount but I just stapled it to a stick and it certainly looks like it will hold up well. Keeps light in my hydroponics setup. Recommended.

This was perfect for our tropical plants that got moved indoors for the winter. Great size, and easy to work with

Item arrived wrinkled, eliminating its ability to effectively reflect light, the solitary purpose of this film most anyone purchasing this product would be using it for. I ordered a replacement and am returning this item for exchange. Not worth even a three star review if the second roll arrives like the first. I am quite sure all 50’ of this item is damaged. There is no way I will take the time install this compromised Mylar film in its condition. Let’s see if the replacement roll is any better. Update: VIVOSUN absolutely exceeded all my expectations with the replacement roll. I submitted my request to return the original roll, which had a crease (caused by the shipping process, I’m sure) that would have critically affected its ability, in my opinion, to reflect light properly (the sole reason for my purchasing the film). Even before I had a chance to drop off the item to be returned later that same day, they confirmed my request and had already shipped it early the next morning. VIVOSUN’s quick follow through saved me an extended loss of productivity. I received the item about two days later. I couldn’t be more pleased with how they resolved my issues caused by circumstances almost certainly out of their control. My only concern now is: Does this roll really have 50ft of film (with enough people who reviewed their product commenting that theirs was shorter than what they paid for) but I’m not concerned enough to unroll it in an attempt to find out. My original review was 3 stars…. Not even a 4.99 star review is merited. 5.0! Great follow up, VIVOSUN!

I love this stuff. I used it to make custom window shades for my truck. I used super strong magnets to hold it on the outside of my truck. The mylar keeps my truck at least 20* cooler in the Texas summer. I also made huge pouches to cover delicate plants when it gets cold here.
