And I never said I was an expert, but thank you for the compliment.OK expert,, what would you use? and here is the question you will not be able to answer, WHY?

A loud mouth? I post here to help people and you come in with that bull shit? Fuck offsarcasm , it was obvious that you're not an expert just a loud mouth.

People oft times get so totally hung up on single words when what has to be taken into consideration in certain applications is two or more words.
　
When it comes to reflective material a high reflectivity material can be very good, but not if it has little to no light refraction.
Mirrors are high in reflectivity but lack light refraction. That makes mirrors a terrible choice for grow light reflective material.
　
If mirrors worked well dont you think that it would have been discovered at least as far back as the 60s?
The U.S. was capable of putting men on the moon in the 60s so I think that somewhere back in the same general era in time, if not well before, if mirrors worked well someone would have been shrewd enough to discover that and long before now everyone would have been using them.
　
Ever wonder why people dont use mirrors?
Do you think it is only because you did not think of it until now, that no one else ever considered it and tried it and actually scientifically researched it and proved mirrors to be a horrible choice to make for a grow light reflective material long before you had your first thoughts on the subject? Might that be at least slightly possible?

the debate over reflective materal is silly
you are both right
how about useing nothing at all and still grow dank buds
my first grow i had no reflective walls , just light and plant
people forget the most important part of the grow is the plant
it will grow if the walls where covered or not
i garantee if you take 2 of the same lights, and 2 of the same plants, and 2 of the same soil setups (or hydro setups) and the only diff. is that 1 was grown with mylar lined walls and the other grown with no walls at all (middle of the room) the out come will be unnoticable mabe a gram or 2 diff if any
maybe ill do this. in a 3 room setup might even paint one of the walls black, one white and one mylar,
people do a lot of talking without trying and they love to quote books of authers who has never tested the reason why they do thing , most people do things because this is the way it has allways been done
mylar user's attack paint users's
paint user's attack al. foil user's
and everone hates mirrors
(people dont use mirrors because they cost to much)
i use paint. flat, and i often look at mylar setups like that shit just looks like mirrors too me, or lamenated al. foil.
you can see a full reflection in it
i notice when some new growroom toy comes out everyone looses there minds over it. as if we wasn't growing gr8 weed way before it surfaced
the light is where the majic happens, if you can get your 600w hps light, with in top bud touching rang, without burning them, the small amout of light bouncing off the side walls is of little concern the plant get 90% of its light for the bulb over its head , to much side lighting may take away from the main cola, it may even be better for you to have no side reflecting surface to promote all the plant energy to grow up toward the light-maybe i went alittle to far just then - but in short what i am saying is let not spend all day on the side when they are of little importance-

Not quoting from books as I've tried them all myself. If you read my early posts I say to avoid hot spots by difusing the mirror using (of many things) vaseline. I also say that this really doesn't apply to people growing with floros because they don't have the heat to begin with. But anyone here can do whatever they want to do. A question was posed and I gave the answer best from my point of view and from my experience. Nuff said.

No problem man. As I said the only reason I'm here is to help someone and maybe learn something myself.

i think the reason nasa uses mirror is because (and i need to look this up ,but i do remimber reading this somewhere) mirrors give a exact dupalcate reflection of what ever it is place in front of- this is why they are used in microscope, telescope, bynoculars, lasers, projectors, vcr's, tv's computers- now this being said - if you place the mirror above the light and angel it right , in thery you could turn a singal light into 2 lights from one source- this has been done with lazers for years. if someone shot a lazer at you you would use a mirror to shoot it back. give your 400w the power of a 800w.
the lumins being reflected from the light in the mirror would have the same light meter reading as the actural light itself it is a twin reflection

Mirrors waste energy by absorbing only a small fraction of the light that falls on them.
When light, which, like radio waves, is a form of electromagnetic radiation, strikes a metallic mirror the electrons in the metal move just as they do when a radio signal strikes an antenna. Pushing electrons around takes energy, which dims the reflected image.
Metallic mirrors reflect infrared light (heat) and if your mirror has imperfections this will cause hot spots, which can burn plants. Please note hot spots also apply to Mylar and Foil and IMO is not applicable to growers using small amounts of fluorescent lighting.
By using a mirror to reflect your light on a wall, you can test for imperfections, if you see an uneven image, with focused beams (normally located at the edge of the reflected pattern) these are known as hot spots and depending on the wattage of your bulb, may burn your foliage.
Metallic mirrors should not be used as a reflector for your grow room as minimizing light loss is important.

Where did you cut'n paste that from, lol...
I don't think i'm going for the best just I think it would look nice,

CiderSpy Take a flash light and shine it on a wall painted flat white. then on mylar then on a mirror and see which one reflects the light of the flashlight the best. should be real easy to find out and ofcourse the mirror is the one thats going to win. That being said if the mirrors are used in floro (tube cfl whatever) grows they won't have the heat build up of say MH or HPS from the light being focused on them. I have avoided focus by using vaseline on the mirrors to difuse them.

Its possible. I can't say, never used tin foil.

Be carefull with the mirrors,, i mean your gonna wanna keep your eyes away from them.. Sounds kinda silly but once there in there youll know what im talking about...
The flat white paint is your best bet... If go this route get the cheapest you can find... More expensive flat white paints will actually have some sheen to them..
