Mylar better than flat white?

The guy in the grow video (the green dude) says mylar is better than white paper, true?

probably i mean just looking at it it looks more reflective which is what you want.

Think of this from a perspective of photography. It is the reflective value that is important here. Glossy white paint is just as good as anything. The big plus is that you can wash it down and keep you grow area clean. It is also cheaper and more permanent. Looks better too.

mylar is better yes

glossy white paint it actually less reflective than flat white...
Mylar is better than flat white!

Trusted growers I've spoke with or read have said flat white is the absolute best. Because it diffuses the light equally as opposed to mylar wrinkles that can scatter the lightwaves... Or something like that...

Flat White!!!

flat white is about 80% reflective. mylar is about 95%

If you install the mylar properly you wont have any wrinkles, making mylar better

i have to agree with Mogie! glossy white paint will serve you just as well as mylar. iam a black/white poly plastic kinda guy mysealf, i think that is the best. but iam useing mylar for my small growroom at the moment...
its realy up to the grower i guess,,,anyways happy growing

anyone tried actual mirrors?

No, but it sounds like it would be a good idea, but if all the old hippys arnt doing it, glassy white an mylar must be better, that or they were to baked to think of mirrors..lol
seattle guy

Mirrors are very inefficient reflectors.

yes MYLAR is BEST...

that being said.. VISQUEEN is GOD..

Here's the chart of percentages of light reflected from Jorge's latest:

Foylon 94-95
Reflective Mylar 90-95
Flat white paint 85-93
Semi-gloss white 75-80
Flat yellow 70-80
Aluminum Foil 70-75
Black < 10

There ya go, and when you buy the flat white paint, tell the paint guy to mix in a packet of fungicide.

HTH

Damn I was so close!

That's wierd about the mirrors no? I'd have thought it would reflect everything, it reflects my goofy mug every morning... Speaking of which, bowl n' bedtime!

And yeah, ferncakes, I'm an American which means I could install it properly. But I won't, because I'm a lazy bastard who just wants to grow my weed and get stoned to watch war on tv, or a tv show about war, or something like that - man I don't even know anymore [/thread derail]

im wondering which would be better, aluminum foil, which i am currently using, or maybe just white paper lining the sides??, do epople ever use paper, should i ??
