VIVOSUN 6 Mil Mylar Film Roll 4 FT X 100 FT Diamond Film Foil Roll Highly Reflective Grow Room (100 FT)

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

Is very durable, tried to scrub off the aluminum coating with a paper towel, no metal marking on the paper towel at all. Cut a 1/4" wide strip off the edge, tested it for stretchability, very hard to stretch, and did curl into a "Tube" shape when I finally applied enough force to stretch it. Product is highly reflective, durable, and priced reasonably, very happy with the product.

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.

It’s Mylar and I’m assuming it will do the job. The roll arrived with deep dents in it and appears to be consistently spaced for about 6-7 ft. I have contacted Vivosun to resolve the problem but have not heard back yet. Will wait for a resolution for a better review. I have received a small refund for the length damaged. I have bought enough to do the project so the problem is solved. Make sure you do not crumple or bend the Mylar as you work as the marks remain and can be unsightly if you are fussy iike I am.

Great stuff this diamond Mylar
