Mylar or Flat White Paint?

Which would be better for a 3x3 closet grow? I'd have to cover the cracks in the door with mylar anyways, but should I just paint it flat white or would mylar be a better option? Money isn't a problem.

White paint is far better than mylar.White disperses the color more evenly.Mylar gets hot spots.White paint is also way cheaper
 
I prefer paint, but many of my friends love the Mylar.

Why I like Paint: It is cheap. It is a lot easier to clean, and does not tear like Mylar.

Peace out

This is also what I have heard.

Another rout if you can find it is Orca Film, I am using it, I got some from my local hydro store. It is kinda pricey but I think anyone who has seen a demo of it would agree its the best of the 3. Check on youtube there are several orca film demos showing you how it works.

Um,...i think "far" is a bit extreme, don't ya think? It might have some advantages, but if i remember correctly, their reflectivity is about the same. NASA engineered mylar, specifically for reflectivity, and it works excellent, so don't be afraid to use it. They'll both perform about the same, so I'd choose whichever one would be easier to install. I wouldn't worry about hotspots either, unless you are running one hell of a light setup, in that area? Sure, i s'pose mylar has the ability to focus light, but by the time it's bounced off the wall, and back to your plant, it'll be well below the intensity needed to cause any problems. Just lay it flat, with no weird configurations, if you want to play it extra-safe. I've read thousands of posts, with peoples' problems, and have yet to ever see anyone have their plants burnt by 'hotspots', whether caused by foil, mylar, or otherwise. Personally, i think you'd have to hang a magnifying glass above your plants, to have anything to worry about.lol

I don't want to show all my cards here but out of anything on this forum, I would almost gamble that I know more about paint than anyone here, however I may not know shit about anything else haha... I have worked for a major paint company selling paint for over 10 years. I am not talking about the shit home depot sells either. If you are not going the Mylar rout or the Orca film I had suggested in one of my other posts use a standard interior or ext paint. I always hear people talking about using FLAT paint and that is fine I am sure. I would almost be willing to say any paint you buy, be it Flat, Matte, egshell/satin, semi-gloss, gloss, high gloss will all work about the same and you probably wouldn't see much difference in the plants performance from 1 sheen to the next but if you really wanna get picky about it and milk every ounce of growing potential hear me out.

I assume the reason people recommend flat is it defuses the light for a more even reflection. The higher the sheen the more focused the light can be at some points. That all being said, here is what I would recommend .....

If you are worried about mildew and shit like that get an exterior paint it has mildew preventatives in it that will help vs. the sometimes wet conditions of your grow area. I also recommend going with a Satin or Eggshell (same thing) finish instead of a Flat. My thought is Satin has a low sheen to it allowing it to reflect more light than a Flat but not so glossy as something above it to create hot spots. Also whats nice about Satin is its much more washable and resistant to marking up the wall. Now all that being said if mildew and things of that nature are not an issue or concern for you go with an interior paint.
The reason for this is usually interior paints have a brighter white base than an exterior. All companys have a standard tint base for pastel colors and another for mid tone and yet another for dark colors such as black. However there is often special colors that are even brighter than typical pastels, what could be called "Luminous" or High Reflective White.

Go to google and search
A87W00150 High Reflective White
Click the top result

This bright white base is only made in a hand full of products, I guess it could be called a special base. The paint listed above is going to be around the $40 per gallon mark due to its coverage and durability. But if you decide to go this way you can ask the person in the store. Whats the cheapest eggshell/satin High Reflective White or Luminous based paint you have? This is often a contractor series product that they maybe will cut you a break on, instead of paying for the top of the line product that they want normal retail customers to buy. Hope this helps.

Ahh something else I just thought of....That company sells sample quarts of Luminous White for under $6 in a satin finish that will cover an area of about 75sq feet. That will undoubtedly be cheaper than anything else they can provide.

Mylar.

White absorbs, not reflecting the UVB spectrum that we cant see, but the plant does.
