Question about tinfoil and mylar

  1. Hey I was just wondering why mylar is so much better than tinfoil and why it wouldnt cause burn spots because it looks just as shiny as tin foil. Would wal mart have mylar? Thanks for the help.
     
  2. Have you ever tried to work with tin foil? It is very hard to not get it crincled. Mylar does not wrinkle as easily. You might find Mylar at Wal-Mart. Home Depot would have it I would think.
     
  3. First off, the purpose of such materials is to reflect light. Mylar is about the most reflective material available, reflecting about 94% of light. Aluminum foil is much less reflective, even if our eyes perceive it as shiny. In fact, aluminum foil is good at reflecting heat (that's why we use it with cooking). A bright, flat white painted surface actually reflects more light than aluminum foil.

    You can buy rolls of mylar online or at a local hydro shop. Wal-Mart has emergency blankets in the camping section that are mylar, though I don't believe these reflect nearly as well as the smooth-finished rolls you can buy.
     
  4. Alright well thanks a lot for the help. I have a home depot just right down the street so I will probably go get some.
     
  5. Ok what a joke. Wal mart=no mylar. Go to the home depot and I ask a lady if they had some mylar. Of course she didnt know what it was so I asked a guy. He took me to this big 4x8 white board and was like here ya go I was like uhhhh what the hell so I said it should come in a roll. Hope Im right haha. So they looked and looked no mylar. I call menards. First a guy picks up didnt know what mylar was. I got transfered to another guy and he kept saying what mylo?....So I had to spell it out for him. He didnt know. Lady got on the phone she didnt know what it was...I give up lol...Whats my second alternative for reflection?
     
  6. Haha, i dont know why but that made me laugh so hard. :smoking: You might want to check art stores for mylar, but if not, would say go to a hardware or army surplus store and get emergency blankets. But its like toasty said, they come folded up and will need to be flattened out to be more reflective. The up side is they shouldnt cost more then 2 dollars per 8x5 section.
     
  7. yeah you can't get it at those places dude lol hydr shops or online.....


    I'm thinking about replacing my mylar with panda film
     
  8. Man are you serious. I had a few people tell me home depot. Ill prolly end up orderin some online then. I hate doin that cuz of shipping but oh well. You kniw any good places I could check out?

    Ok I just found this...http://cgi.ebay.com/Mylar-sheet-Hyd...oryZ3186QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

    Does that look good? And what does it mean when it says its double sided. It has that it is 7x4 so would i really be getting 14x8? Thanks for the help guys.
     
  9. he tried to sell you melamine instead of mylar... i am not sure why those guys dont just say i dont know let me go ask instead of trying to bullshit everyone! :rolleyes:
     
  10. i tried hardware stores as well, I only found it in a headshop, and it was dam expensive for what it was.
    So I got a can of Gloss High-White Spray Paint and painted the inside of my cabinet.
     
  11. Well I guess Ill prolly get it from that guy off of ebay. 15 bucks for 4 sheets that are 7ftx4ft.
     
  12. High bong! That sounds expensive to me. here's 4x50 for a betterbprice. Though I wanted to add that flat white paint is alot eiser to work with especially over several grows. im so sick of my mylar, im ready to rip it all out:devious: ! peace, TBug
     
  13. where is it cheaper at? that 15 bucks includes shipping as well
     
  14. Just google "mylar roll" or something like that and you will get places that sell 25 foot rolls for about 20 bucks I believe.
     
  15. Tinfoil if not properly spread out/flattend can create hotspots and burn/dmg your plants..
     
  16. Tip on applying mylar. Pick up a can of spray adhesive and a cheap paint roller. Spray on the adhesive, apply the mylar and smooth down with the paint roller. Make sure you mask off any mylar already applied before adding more mylar. The spray adhesive will drift in the air and if it hits your mylar, you'll be replacing it. I tried a staple gun and it was a disaster.
     
  17. Lil more advice get uhh well dern Oh 2 mill not 1 . 1 ml gets crinkly also thicker the better I say! Peace DaMilkman
     
  18. mylar is great but, i find that plan white is best for reflecting only because mylar dose not distribute the light evenly
     
  19. They make stuff that is even better than Mylar. It is called foylon. According to George Van Patten, here are the best reflective surfaces:
    Foylon 94-95 percent reflected
    Reflective Mylar 90-95 percent reflected
    Flat White Paint 85-93 percent reflected
    Semi-Gloss White Paint 75-80 percent reflected
    Flat Yellow Paint 70-80 percent reflected
    Aluminum Foil 70-75 percent reflected
    Black less than 10 percent reflected

    He does not give a percentage for reflection of mirrors but, he does say that mirrors reflect light but, much less than Mylar because much of the reflected light is lost when passing through the glass.
     
  20. this is what they look like when you buy it at walmart in the camping section [​IMG]
