Highly Reflective Mylar Film Roll 4FT x 50FT for Outdoor Grow Room Indoor Decoration Aluminum Paint Coated 2 Mil Silver

This VIVOSUN Mylar film is fantastic! I was a little worried about the thickness, but it's perfect—not too flimsy, but still thick enough that it feels durable and won't rip easily. Cutting it to shape was a breeze, which made my little project so much easier. I'm using it to grow some cactus seeds and it's working great. The reflective material does an amazing job of bouncing light back onto the seedlings, and it definitely helps with heat retention. The best part, though, is that you can see through it just enough to check on everything without having to take it down. Plus, it's a great way to keep my nosy neighbors from thinking I'm running some kind of illegal grow operation instead of just pursuing my hobby! Highly recommend it.

There was more than enough in the roll to cover the inside of a big pop-up greenhouse that I bought recently. I left the front uncovered because it faces a southward facing window and I wanted some natural sunlight to get in...But the sides and back are all covered with this reflective film and it is really making a huge difference for my plants. Since I chose to leave the front uncovered I had some extra that I used to double line in a few places so less light would escape. I also bought 4'x6' blue tarps at the dollar store near me and lined the bottom and back with it. This really helped to keep even more light in. It was a relatively cheap set-up and my plants are all looking happy & healthy. Definitely well worth the $ spent.

Great product. Spray adhesive and some scissors and you’re ready to install.

This item was used to reflect the sun light. WORKS GREAT. be careful it also reflects the heat. Almost started a fire. But is fantastic for what i needed it for.

I have not loved a product of its kind like I love VIVOSUN in my entire life. This product and I were so meant to meet! The first photo shows the space prior to VIVOSUN. With this product you can be endlessly creative and playful. (I should have gotten the biggest roll, but it's okay, I will get more when I run out because I keep finding things that VIVOSUN will make far more beautiful and enjoyable.) -- The third photo shows two small filing cabinets that I got as base for my glass top desk. I could not stand the idea of having two big objects obstructing the light and view; the solution? Cover them with VIVOSUN. <3 <3 <3 The second photo shows the door, which used to be horrible; it now is artistic, beautiful, reflective of light and enhancing the sense of space, like everything where VIVOSUN goes does. I couldn't possibly love this film more. I would cover an entire wall with it in a room, but maybe in the future :-). I cannot say thank you enough for making this awesome product and also for making it affordable.

For me, its one of the greatest product I have ever ordered, coming from a Pro Photographer, you can order it

Very thin material. Works good enough but looks to be single use.

Perfect for putting behind my grow lights on a shelf, and blocking 98% or so of light from going outside! I was worried about durability/ not being reflective enough, but it exceeded my expectations. It is very thin/ light, but inside it looks like a slightly distorted mirror (because it's not perfectly straight). It might be slightly less bright than an actual mirror though, but I wasn't looking for a perfect mirror. At night, before my grow lights were lighting up the entire backyard. Now with this behind them, you can barely see through the film at night unless a couple feet away (all I have int he room are the plants, so no need to close the blinds)! If you're looking for a near (but not perfect) mirror surface, that's light, thin, and durable enough for how thin it is (I accidentally rubbed it against the metal shelf, and the surface didn't rub off), then this is great! NOTE: One side is much more reflective than the other (like one is 80% vs. 98% looking). The inside of my roll looks like a mirror, whereas the outside looks closer to aluminum foils reflectiveness. So make sure you pick the mirror finish for reflecting light!
