hey seems like your getting alot of flack here.........not be a dick but everyones pretty much right mirrors are not ideal and theres better easyer things to use......
I read somewhere that mirrors will reflect the light back in a beam but mylor and paint will refeclt the light back in all dirctions something about how it diffuses the light and reflects it back out in all directions less intense but more evenly spread out........
Like if you signal a plane with a mirror the light reflects back as a small beam of light. you dont want beams of light reflecting back and fourth in your grow space you want the light to reflect evenly across your area.....just somting to think about.......and yes i heard that it also absorbs light too......not to mention they are heavy hard to install and can easly break....so when you look at all the pros and cons seems like its all cons and no pros really..........but if you already did it then ya seems like your just fishing for people to tell you what you did is right....
