Dude, just go to home depot and buy an emergency blanket for $1.98 in the camping section. This is just the same as mylar accept is has creases in it.

Mylar is just aluminum metalized to fiberglass. The difference between mylar and shiny aluminum foil is negligible.
But use a reflector! You're wasting over half your light probably if you don't! Metal > paint -always.

Aluminum foil reflects between 50% and 55% of light rays. Any crinkles or wrinkles will reduce that percentage range and will also cause hot spots due to the unequal diffusing of light rays.
Flat white paint reflects between 80% and 85% of light rays and does so evenly.
Mylar reflects between 90% and 92% of light rays though any damage to it will reduce that percentage range. Mylar is not inexpensive so many people purchase thinner Mylar to save money but it is easily damaged. If not evenly applied, not totally flat it will lessen the equal diffusing of light rays.
The problem with the emergency blankets is they will not be perfectly even, not totally flat and they will diffuse the light unequally and just as crinkled aluminum foil they can produce hot spots.

Man, I am using an emergency blaket. I have een using it for about 3 weeks, I am in week 4 of flowering. The blanket works all my lower budsites are forming nicely, bigger than popcorn.

This guy just repeats the same bullshit in different threads.
Only his numbers change! LOL!
Mylar is aluminum metalized to fiberglass. (I said that already!
)Hot spots don't exist from aluminum foil. You've never had one. You just regurgitate what you're read from other fools.... Not good, man. Not good at all.
Think for yourself.

You can use the wrapping paper called "polywrap" as well and it works just as good as mylar. Use the reverse side that the decor is not on. The "mettalic" wrapping paper is the same shit. When I first started my grow I bought 3 rolls of it from the dollar store and it worked great. I later found a huge roll of mylar at Goodwill for 3$ so I starting using that just because, but either work just as well.

So did I waste $30 plus $11 for shipping to get this stuff. I thought it might last longer and be easier to clean.

That is correct, other than the it being bullshit part, because the same questions about reflective materials are asked over and over again and the same inaccurate information about various reflective materials is repeated over and over again each time a question about reflective materials is asked.
If everyone else will agree to stop repeating what they say that is inaccurate and misleading then by all means I will not need to supply the information I keep repeating.
Giving someone who does not know something misleading or inaccurate advice is not in any way helping them so instead of doing what others do I do my best to help them.
Aluminum foil can and will produce hot spots regardless of what you like to believe or may want or need to believe.
It is a proven fact that aluminum foil can and will produce hot spots. It is also a proven fact that aluminum foil is very low in reflectivity compared to other reflective materials.
So why use garbage when other products are available that are much better and some are inexpensive and are very easy to apply?
But by all means do not take my word for it. I have only been doing this since 1972 or 1973 and have tried just about everything one could think of, including aluminum foil, and have spent decades reading about such things and exchanging information with others who grow too.
Just out of curiosity, have you been growing since 1972 or 1973?
Were you even alive in 1972 or 1973?
Most people who claim I am not accurate in what I say were nothing more than a gleam in the eye of two strangers at a Guns N Roses concert when by then I had been growing for two decades or longer.
Do you happen to be one of them by chance?
Something tells me you likely are.

Brick Top,
Where do you get your information?
Aluminum is neither proven to cause hot spots or of poor reflectively. The two are *MUTUAL OPPOSITES* of each other. You make *ZERO* sense.
"Hey dudes, this thing is a great reflector, it can cause hot spots!"
"Oh yea? Tell me more!"
"It's actually a horrible reflector and what i said is just bullshit."
"That makes sense, now that you mention it."
This is *your* argument. *You* fail.

Actually just about every piece of mj growing lit says the same thing. Even Jorge's CannaBible says it.

I never paid for any literature.
Regardless, how do you know your right and every experienced grower out there is wrong?

Because your generalization is inherently flawed.

From a combination of roughly 37 years of experience, exchanging information with growers I personally know, from having been a member of numerous pot growing websites and also from extensive research throughout the years that included many top growers as authors of the information.
When you have equaled what I have done get back to me.
Yes it has. You just do not believe it has or just do not know it has or you just refuse to accept it has.
You lack experience and knowledge and give out horrible advice when it comes to reflective materials.
Obviously you tremendously lack reading comprehension skills if you believe what you wrote sums up what I wrote.
I have no interest in arguing with people that are either ignorant, pigheaded or both so I will not respond to anything more you say on the subject in this thread.
I only advise people to not take your advice because you are giving them inaccurate misinformation that could very likely cause them problems, some very severe if they use HID lighting because aluminum foil is a fire hazard when used with HID lighting.
If they want to ignore the advice of someone with roughly 37 years of experience who has tried everything imaginable and has exchanged information with untold numbers of growers over the decades and has researched very deeply into the various aspects of growing and who is part owner of a nursery that covers roughly 12 to 14 acres of land and who has four family members with degrees in horticulture and who I have asked questions about virtually everything growing related that is their prerogative.
I only pity them if they take your inaccurate misleading advice and information over mine.
Have a nice day .... message ends.

I think your argument is entirely flawed becasue you havn't disproven what the canna growing culture has known for a long time. You bring your greenhorn study skills to RIU and assume to know more than others who have been involved in this same field of study for alot longer than you and have alot more cred than a college student with an ego.
And just what is my generalization, anyways?

That is correct, that is one of the MANY that I have read but you just cannot tell some peole things they do not want to believe. They get a little experience and they like to or need to believe they know it all and they refuse to accept what those who are more experienced tell them even if it comes from someone like Jorge.

Yet you are impotent to provide any proof of your statements beyond your 'promise of experience'.
I offer the promise of repeatedly proven tests and repeatedly proven scientific measures.
