VIVOSUN 6 Mil Mylar Film Roll 4 ft x 50 ft Diamond Film Foil Roll Heavy-Duty Reflective Film

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! Read more

When setting up the second grow room in my basement for my larger floor plants, I did the research to find out the most reflective surface for the walls of my grow room. This room had plastered walls with a stucco finish that collected dust and dirt. In my research, I found the options for wall covering and reflective qualities to be white flat paint, white gloss paint, flat (thin) Mylar, and diamond cut Mylar. Of these options, the diamond cut Mylar had the best reflective qualities and was the best for consistent reflection. The room to be covered is approximately 20" X 16", so I bought the 100' roll. This has been a "learn as you go" experience, but we can hang a panel in about 15 minutes or less now using staples to hold it to the wall. To hang on a wall quickly, put the roll on the floor, pull up the end to the ceiling. make sure it's hanging straight, and staple it at the ceiling. When you are sure it is hanging straight, cut it at the bottom using a metal ruler and a box cutter. Staple it at the bottom making sure it is taut and straight and then on the sides. I wasn't sure how much we would need when I bought the 100' roll, but it's enough to cover the walls in the entire room. As for the smell reported by a couple reviews, there is absolutely no smell on the roll I received. This Mylar is highly reflective as plants I have placed away from the light canopy are growing well. Having covered the stucco walls in this room with this Mylar, it looks like a shiny, light grey wallpaper that is very attractive and also very functional for my plants. The front of this Mylar is very reflective and the backing, although not cloth, is a plastic feeling material not much different than some of the lined. light-blocking curtains available. I don't think it would be machine washable, but this Mylar could easily be made into light-blocking curtains. It is flexible and hangs very well. If you plan to make holes at the top of panels, it would be best to use grommets so the weight of the material does not tear the holes. I am very happy with this Mylar for my purpose, but I'm sure it would be useful for so many other applications. UPDATE 07/09/20: I have had this Mylar installed in my plant grow room for a little over a month, and the plants seem to be doing better. My avocado trees aren't under lights, but are growing and doing very well with only the reflected lighting. UPDATE 7/15/21: I have had this Mylar installed on the walls of my grow room for over a year, and I still love it. It has held up very well and is impervious to water. Every now and then, it has been splashed with water when I was watering, and the water just ran off. A few times the water left watermarks after the water dried, and I just wiped them off with a moist paper towel. This Mylar still looks every bit as nice as the day we installed it. It was definitely a worthwhile investment. I hope this review was helpful for you, and I will update the review if my opinion changes. Read more

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. Read more

I have a growing area in my garage & was looking for something to kind of insulate as well as be reflective and be easy to handle. This film/sheeting had the properties I was looking for: 1) at least 6 mil thick (.006), 2) diamond pattern reflective surface on one side 3) easy to work with when wrapping over PVC frame. I would have preferred a black backing vs white but that was not an option. The material is thick enough not to tear though not as thick as a pre-made grow tent. It does try to 'kink' a little when lifting or folding if the whole length isn't lifted up at the same time though the 'kinks' do smooth out once it's straightened correctly. The material is very easy to cut. I haven't put any holes in it so can't say how well they would hold against ripping. Once unrolled for a bit, the curl (from being on a roll) straightened out & the material hangs nicely. All in all, this is pretty robust material for a DIY growing tent. Personally, I think a pre-made grow tent is worth it as the material is thicker, it's fully sealed and has zippered openings & vents. The cost isn't that much more. However, I needed something taller than 6.5' which is the height of most tents. Read more
