VIVOSUN Horticulture Highly Reflective Mylar Film Roll 4FT X 50FT 2 Mil

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.

Stuff is great, it' going up on my grow room.

Used to make DIY grow tent and it worked great! For the price, it was worth it to buy the 100ft roll to have extra for other projects or if I tear this tent down I can rebuild. Very reflective on both sides and strong but easy to cut with sharp knife or scissors. Good if you don't want to spend money on expensive grow tent and don't mind constructing one with cardboard and tape. Easier with 2 people to work with in large parts to avoid accidental creasing but it is very resilient to creasing in general.

Material thickness it is 2 ply and is actually wonderful we lined our basement walls and did a beautiful Pond and house plant Sanctuary for the turtles great reflectiveness it's easiest to use heat retention it's all right but the quantity in size for the money I mean it's a no-brainer if you need to reflect light get it

Exactly what I was looking for. Amazing product, works like a charm. The 50ft roll is not as much as I thought I needed. Will be ordering more soon. I recommend to everyone looking for this type of reflective mylar, only get VIVOSUN, it is of amazing value.
