VIVOSUN6 Mil Mylar Film Roll, 4 ft. x 50 ft. Diamond Film Foil Roll, Heavy-Duty Reflective Film for Grow Tent, Warm House, and Grow Room (50 ft.)

You could fry an egg on the shingles laying next to this stuff but the reflective wrap felt almost cool to the touch!!!!!!?

This is a great product.. exactly what I was looking for,I turned my 8x6 room into beautiful grow room . The material is just like a grow tent ,minus the canvas of course. You won’t be disappointed

Disclaimer: I have not used a light meter to test it’s effectiveness.My newest hobby is Kratky hydroponics ( not pot, but salad-type leafy greens and cooking herbs). Surprisingly, the grow lights hurt my spouse’s eyes… But my spouse is sensitive to all kinds of things so perhaps that’s not so surprising.So instead of proudly showing off my grow to hours to myself and all my guests, I need to 😕 block the light. As long as I’m doing that, I might as well help the plants!So I bought this thick mylar sheeting. I attached it to a drapery rod via shower curtain hangers and, to make it look pretty on the outside, and also to celebrate My hydroponic hobby, I fronted it with shower curtains with green plant art. The mylar being backed by white (Unlike the black of grow tents) Is a huge part of why I picked this product. It’s in my main guest entertainment area and, unlike a secret pot farm in the basement, looks are therefore important.The shower curtain is wider than this roll so I used one for width and an extra 23 inches (2 strips). I haven’t attach them together but may if it seems called for later.The thickness of this material leads me to believe that it will last pretty well for quite a while. I the thickness, however, was a bit hard to use a hole punch with… My whole punch lost its effectiveness after the first 10 punches Making the final 14 punch is very difficult. (24 because I’m setting up my 2nd grow tower.)So far, I am super happy with my combination of materials, thir effectiveness, and their appearance.I did notice a little bit of fragrance which seems to have dissipated after a few hours of being in a windows-opened room. Four stars is my top rating until I gain more data which leads me to add or decrease a star.

Much heavier and tougher than expected positive surprises

Very Durable at 6 ml., Holds up to being stapled to the wall, then a good 2 1/2 in. Box Tape to cover seams @ staples helps make the Rm. airtight. Reflects your light more @ helps insulate the area. Good work with this foil.
