iPower10 x 10 ft Black and White Panda Hydroponics Poly Film 5.5 Mil Highly Reflective, Waterproof Plastic Sheeting, for DIY Grow Rooms, 10 X 10ft, Greenhouse

doubled the light great product sturdy and easy to clean

I have a two sectioned indoor grow room and needed a dark area for a few plants that require less light times, instead of another grow room, I split the bottom of the second room and used this for the time differences. Works perfect and no light gets in.

I used this to weatherproof my bedroom window that has an air conditioner in it. cut it the size of the window and cut a hole in it to let my air conditioner poke through it. taped it really well along all sides and not only does it make it an air tight seal that keeps out the outdoors but it also acts as a black out curtain so my room stays dark for sleep and entertainment (movies, video games, etc.).I have enough left over to do it 4 more times so I can replace it if I have to exchange my air conditioner or repair the window.Highly recommend.

I can confirm this material is 100% opaque. If I hold up my phone's flashlight directly against it, in a dark room, nothing gets through. I used this to black out the windows in a bedroom, and it worked very well. Even in direct sunlight, the room remains pitch black. And from the outside, all you see is a white "curtain."The photos don't show it, but the material has a high gloss on both sides. It has the appearance of polished latex, and tends to attract dust easily. The black side had a few oily fingerprints, apparently from the vendor's handling, and I was unable to clean them off (using glass cleaner).I deduct one star because the material was folded tightly into a 1.75 x 6 x 16 inch box, instead of being rolled up. There is no way to remove the approximately 5 x 15 inch crease pattern that results. At least the material was not further bound up with tape, as some other vendors have done.

Despite my preference for a thicker texture, this product is still suitable for most users due to its ease of use and high reflection rate. Also with it's ability to black out a room!

I use this product to make a 2x4x4 ft tall grow tent and it worked great very thick material works exactly as described

As described

This plastic sheeting has a great thickness and durability, About what I would expect; Especially with the high price point of this product. The not so accurately cut sheet I received only measured 118” x 118”, And I measured multiple times on flat hard flooring. 118 inches is a stretch, literally, Because I tried to make it 120“ x 120” Like the description says by pulling and tugging to no avail.
