Sybstitue for mylar is this true???

i found this in the growfaq plz someone tell me if this is true or not
Is there a similar substitute for Mylar?



Contributed by: Stickydank

I've discovered the cheapest Mylar around-- only 2 bucks$! You save 18 bucks$ a roll! It?s a Christmas present wrapping Mylar called Polywrap



- Waterproof
- 50 square ft. a roll
- 1 mil (@ .001 inch) thick X 3 1/2 ft. wide X 20ft long.

Note: Only buy the very Bright and shiny Mylar-type wrapping!

uhh can anyone answer me or is the growfaq actually wrong???

yeah the stuff IS mylar. Its a thinner sheet that they put wrapping paper designs on the back of so that the pictures are all colored and shiny.

thnx man +rep u juss saved me lots of cash and do u see how fukked up the economy is put mylar on a christmas wrap for 2$ and sell a roll of mylar its self for maybe 20$ kinda fukke dup

even those emergency blankets they sell at camping section at some walmart or whatever works

anything made for growing or is commonly applied to growing is instantly jacked up in price just because they know people will pay it.

the thicker the mylar the more light it reflects though so your getting better quality with the more expensive thick stuff

well why not juss fold it over and over again so it gets thicker

i guess in theory that may work, dunno though. good point.

i like how you think, thanks for the idea +rep

Because any light that can be seen (like through wrapping paper) has actually passed through the mylar. Even if you double it up the light is not going to bounce and pass back through.

It is still better than most things though.

i was thinking that but didnt want to post up without experience

it double layered is going to prevent as much light from actually making it through it though. with green saran wrap you can keep adding layers and layers of it on something and each layer you make is going to prevent a little more light from passing through.

True,

But in this case we are not trying to prevent light from passing through something. We are trying to reflect as much light as possible back on the plant.

Adding layers and layers to colored saran wrap allows the light to be captured between the layers and dissiplated as heat energy. It will not however provide much reflectivity to provide energy to the plant.

flat white will do the trick, too.

but the reason it passes thru is because it think so make it hticker

that makes no sense even if you assume that you meant "but the reason it passes though I think, because its so make it hticker

This is 100% true I also like the way you think, its the way I was thinking when i set up my grow room. with emergency blankets, all it took was 2 layers to COMPLETELY block out the light. Even one layer does a pretty good job, but the reflectivity is compromised by all the folding they do to the emergency blankets. One blanked is under $2 also and is decent sized. maybe not as many square feet as you would get on a roll of wrapping paper, but it folds out to be pretty big, like a little more than 6'x4', maybe closer to 7'x5', there is less taping involved because you aren't working with all those narrow strips or wrapping paper. Be sure to get plenty of tape, you'd be surprised how much you need. I needed double what i had origionally estimated... and I even used math. there are always unexpected nicks and little tears to patch when you use the cheaper stuff... but i think it's still a huge savings. after all, whats another roll of reflective tape? another $2?
