space blankets are very cheap also and reflect around 93% of the light back.

Hey Guys,

I thought I should let you know what I use for reflection in my grow room.....

I went to Dollarama... a dollar store and bought the reflectors for in car windows (to keep the sun out)....they seem to shine and reflect really nice for 50 cents a piece.

I did the same thing in my grow room (closet). I bought two for mini vans at wal mart fro like 2.30 each and before I was going to use a mirror tha was going to run me like 5.90 each and i would have needed 2 of them

Yes , Im glad u didnt choose the mirrors because they don't reflect light....

Its kinda like a trick question - you would think a mirror would do an awesome job but it doesnt.

well I guessed I lucked out then, heh.

Its not that it doesnt reflect light, it doesnt refract light.

^^emergency/space blanket...they're also made of mylar and reflect around 93% of light back. A lot cheaper than buying mylar by the roll from some hydro place that hypes it up.

PuffTheMagicDragon · Apr 27, 2007

mirrors absorb light not reflect alunimum foil is 60-70% reflective flat white is 70-75% reflective and space blankets and mylar are in the 90% and above range

space blankets!!!! haha, last week i called a million places looking for mylar... i did find it 10 dollars for 25sq ft.... i think it was pretty good? LOL it was at a hydro shop too.

gosh i didnt know places like that existed. very fun though to go look at everything they had lol

how many of you prefer the mylar over space blankets?

OG FAQ said:
Emergency Blankets:These are ultra thin polyester blankets that are sold in most camping stores and are constructed of a single layer of polyester film that is covered with a layer of vapor deposited aluminum. It is not very effective at reflecting light because it is so thin. Holding it between you and a light source, many small holes are noticed at the intersections of creases and the entire blanket is translucent to begin with, this coupled with the many creases that are in it when you purchase it takes away a significant amount of it reflectivity. It is very easily creased as well which also detracts from its ability to reflect light. And while it is reflects nearly 90% of radiant heat energy, it is only able to reflect around 70% of the light. The largest advantage of using this type of material is that it is very cheap and therefore easily replaced. Emergency blankets can create hotspots if not attached flush to the wall so it is important that no air gaps exist between it and your supporting wall. The easiest way to attach this is to use tape (Aluminum or metal tape is recommended), as it tears very easily once it is cut or punctured.

Just though I'd clear this up a lil. those space emergancy blankets because of there look are often confused with true mylar which is a different material all together. Go with flat white paint or white poster board if you want cheap. IMHO
