VIVOSUN 6 Mil Mylar Film Roll, 4 ft. x 25 ft. Diamond Film Foil Roll, Heavy-Duty Reflective Film for Grow Tent, Warm House, and Grow Room (25 ft.)

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.

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.

I purchased this hoping to attenuate harmful EMF's coming from my Smart Meter. I cut 2 pieces from it: one I hung on the inside wall, essentially behind the meter. (an adjoining wall prevented me from placing it directly behind the meter). The other will complement a piece of aluminum screen that sits under my headboard in the 2nd floor bedroom directly above the meter (I was having heart arrhythmia at night). I did a before and after test with my RF Meter, and showed a reduction of radiation (on the first floor), but will need to do additional testing when time allows, esp in bedroom, to calculate effectiveness. The 6 mil is VERY nice; very similar to the thickness of a quality plastic shower curtain liner, which the white side feels exactly like. But it will crease, so handle carefully to prevent lines. That being said, I believe it is quite sturdy enough to tolerate metal grommets for hanging with shower curtain hooks as another reviewer suggested, with more probably better to distribute stress. I used four ratcheting tarp clamps that have a rope hole at one end, and hung the piece with nails thru the rope hole. That's what desperation looks like! I like that the white backing is less obvious, now just need a solution for my tin foil hat LOL! Actual Measurement of piece: 47.5"(inches) wide x 12.5' (feet) long. I was so grateful for the extra 2.5 feet! Item arrived undamaged rolled onto a sturdy tube, wrapped in plastic and inside a long box, so it is pristine with no folds. If meter numbers are good, I will be buying more of this very nice product. Can't think of any cons. WIll answer any questions if I can, and will update with accurate numbers. At least at night, turn off your wifi routers and get your cell phones off the night stand away from your head! Me, I'm going all wired so I can continue to live in my house.

Great product and I have no complaints as far as the quality of the product itself. My only complaint is that I have been shorted a foot in each of the two rolls that I’ve ordered! If you are looking for exact footage I’d suggest ordering a size up. Unfortunately, I did not measure the par intensity before and after using the DM but I have noticed a significant difference in overall lighting and plant growth.

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.

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.

This is exactly what I was looking for I built a custom sized 20x30 inch grow tent this is all I needed for the walls and ceiling it’s pretty much light proof and a lot easier to work with than the metal coated Mylar film much easier to cut and it does not wrinkle as easily if you are looking to convert a closet or make your own grow tent this is a great choice if you use the thinner 2mil you will have to something behind the film to make light proof with this stuff you don’t I made a pvc framework out of 1/2” pipe the whole thing cost less than $30

I wanted something a bit more durable than the thin flimsy Mylar I used for my last garden. This material is thick, durable, and has worked exactly as I had hoped. I used a grommet tool to set ring grommets at the top edge of my reflective curtain, and used zip ties and magnets to secure the curtains to the metal lettuce racks. Thick, durable, highly reflective, and a nice clean/neutral white on the outside. My only gripe - the end cuts were not perfectly square, but they gave me a bit of extra length so I was able to cut the roll ends square and still have a bit over 25’. I would buy this again with no hesitations if I expand my winter garden further.

juste parfait

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.

I had no problem with the product, received it in good condition. Installation was not complicated. Like many comments here, I received a roll that missing 38 inches out of 600 inches (50 feet), 6.3%. If I use the measurements provided in French 152.4 meters, I just received 14.2 meters, I received 9.3%). Usually, sellers deliver exactly on the measure they publicized or slightly more.

Got this stuff to fix my RC planes and have used it on two planes so far, it dose on nice and easy, that one roll will last me a long time, worth the money.

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