Mylar vs Panda Film vs Flat White Paint?

[James!]

Jeeeeeez!

Weegogs calm the fuck down we are having a creative and resourceful discussion your input is greatly unappreciated by everyone. If you want to say something bring some evidence or something to back it up ok !!

As for everyone else thanks for your input any more will be appreciated ey!

I used mylar on my walls. In a tight space it was a nuisance always snagging and getting in the way when I needed to move stuff around on the walls. This time I am going with flat white paint. Easy, simple & cheap.

This is all to try and capture the peripheral light which is pretty feeble compared to whats going on on the top. Does it really make sense to go to the effort and expense of trying to collect 10% more of what is probably already only 10% of the light? It comes out to a few % at best.

Good point, zvuv. Nothing wrong with discussion though, academic as it may be. What doesn't make sense is how some people personally attack others who happen to disagree with them. I guess they think it strenghthens their position, but it doesn't

Yes. A constructive discussion is always fun and good even if it's about how many joints you can balance on the head of a seed. And yeah, acrimony and personal attacks have no place in these threads. It's like pissing in the pool. Spoils it for everyone.

Of all the reasons to go to war, Mylar vs Panda Film seems the least compelling

 

[James!]

So to sum it up

Mylar

Pro's
95% + reflective.
Cheapest type of reflective film available.
Easily stuck to a surface.
Convenient.
Light weight.

Con's
Reflects heat (So hot spots occur).
Tears easily.
Hard to clean.
May fade and loose reflectivity.
Difficult to Join pieces of Mylar to each other.
Thin (thickness wise 1mm - 2mm).

Panda Film

Pro's
90% + reflectivity.
Easy to clean.
Thick (thickness wise - 6 mm +).
Easy to join sections of Panda film to other sections of panda film.
Blocks light from escaping "Black side".
Easily stuck to any surface.
Can divide rooms with sections of Panda film.
Does not reflect heat.

Con's
Expensive alternative to Mylar.
10-15% reflectivity drop over Mylar
Heavy.

If iv'e missed anything Pls. shout

Peace

Diamond reflective sheeting that i posted about needs to be on this list as it is not see through and thick enough to handle easily. I stick mine to the walls with Spray on Carpet adhesive that can cope with temps in excess of 50C.


"Diamond Reflective sheeting is a premium reflective sheeting which has all the reflective qualities of Mylar but with more even light distribution due to the diamond pattern. 100% Lightproof, Diamond Sheeting is flame retardant, easier to handle and much more resistant to creasing than other types of reflective sheeting. Also, uniquely the reflective metal layer is sandwiched behind a clear protective PET film that protects against heat, humidity, moisture and handling"

£4.25 for 1.4 x 1 metre, thats mental, check this out it works brill. i use it. price includes vat and is 2 metre on the roll so the price is for 2 metre.
this stuff is 100% lightproof, 98% light reflection, 90% heat reflection, a pet film to protect against corrosion, and best of all, a reflective flowering spectrum built in to enhance flowering.
non fireproof, but then, everything burns, even joan of arc burned.
and only £2.10 for 2 metre, ($3.39).

reflects heat so hot spots occur,,,,,, WRONG

its light that causes hotspots, a small crease in a flat reflective surface. a bit like putting a magnifying glass under the sun and over the palm of your hand, if you move the glass up and down changing the distance from your hand until the white light mark becomes a small dot, this will burn through your hand like a steel gas burning/welding torch, if i tied you up and held it there, then your hand would burn to a crisp eventually.
while you screamed the fucking place down.
IT IS LIGHT PRODUCING HEAT.

to be able to reflect heat back in to a growroom is excellent properties of a protective film, let the fans remove the reflected heat.
if your growroom is too warm, up the fan size.
remember!!!!!! fans can never be too big, but too small means noise and heat.

panda film is by far cheaper then mylar. you got that one wrong, and it is not less reflective they both claim the same.

also you anake whole grow rooms out of panda film and not mylar. mylar is see though

 

[dsnutts]

reflectix from lowes I love it....

 

[ChronicClouds]

I think mylar tears too easy to be worth what you spend. However on a budget the emergency blanket is perfect. I use Panda film and I'll admit its not quite as reflective as mylar but it's 6mil minimum and black on the other side to prevent mold growth. Really I think even white paint is good enough for reflective purposes but I prefer the panda. Its perfect for sealing up your room and making it easier to clean.

listen mr. know it all , i am never wrong , the stuff i use is 98% light reflective, 80% heat reflective, Spectrum enhanced to increase flowering yield, PET coated to protect against corrosion and wear, 100% lightproof. and you can get strongman to try and rip it, but it is as tough as hell and cheap.it comes off the roll 2 metre wide ( 78.5 inch ), so it is £2.10 gbp ( $3.43 ) for 2 metre square, ( 78.5 inch x 39.4 inch ) 78.5& x up to 100 feet long. so sit on it and swivel.

you are the rudest mother fucker i seen post i dont care for any of your opinions and im sure i speak for all people here, as for mcpurple you are right hey i forgot to factor in the size of panda you get for the price!!

Foil tape, used for ducts, works great, it's cheap, effective and goes around anything. And you can use the insulated tape or the regular tape. Some may say it's not very good but I've always used it, trick is to apply it evenly otherwise it will not only look bad but will leave spaces. And the heat thing, it can get hot but after all it is designed for that.

 

[anonimouse]

I work with light for a living... Film and TV production and because this thread was hilarious I wanted to touch on a few areas that were not mentioned.

SILVER is more reflective, however what is a silver reflective response? Well, silver reflects light more harshly and specularly. The angle of light reflection is less controllable and because of this harsh bounce it can create hot spots.

WHITE in terms of color is the presence of all colors. This means less reflective BUT is much more broad. The reflective surface of white creates a softer diffusion and more controllable light bounce.

You can use GOLD too depending on what color spectrum you're bouncing back. But we won't get into that.

Mylar is transparent so why not paint white then Mylar over it.

HEAT is a by product of incandescent tungsten light, HPS, MH, and HMI lighting. You won't gain any more heat than what your light puts out based on reflection material. But think of a magnifying glass beaming the suns light... It will create a focal point and begin to burn. Most high grade lenses and glass are silver coated.

Take it for what it's worth.

 

[Mr.Gr33nThumb]

I use the emergency blankets also

check out my dresser cab , the inside is covered in it

well the bottom is not , its shitty foil tape lol

but the front and back and the sides are all emergency blanket

I use to grow in a cabinet like that same setup it gets tight in there lol especially if your not using less
