nobie question about mylar

i figured out where i can buy some mylar but dont know if its the right stuff, anybudy know if you can use survival blankets(which are made out of mylar) as good reflectors without buning your plants ( i think they are the silver color

They will work excellent !

Perfect. A lot of this hobby has to do with you being able to adapt and design grow rooms based off of your budget. Mylar costs an ass load.

Or if you can find Mylar wrapping paper at the $ store will work also.

survival blankets will work well

thanks a lot guys youll be hearing from me again lol just starting out

Me too. I had the smame question three days ago, went to lowes to see what they had, was hoping they had mylar.
But found a 4 foot X 13 Foot sheet of styrofoam one side flat white the other side is covered in a foil type of reflectant. it was like 13 bucks.. i was stoked,
It was mad easy to cut/install

that's what I used....both sides seemed just as shiny to me, is there any advantage as to which side faces out reflecting the light?

It should be the side that disperses the light the most. but are both sides not just the same material?

like i said, I couldn't see a difference

imo just get some flat white paint and paint the walls. move on to the next project. warning you if it is not perfectly installed like wall paper you will be ripping it down and waisting money you could spend on other things. seen many a mylar type stuff flapping in the wind...you will be pissed.

I got a 25ft roll of 2mil Mylar from the hydro store for like $20. You can get it online from Home Depot for less then $30. Those Styrofoam sheets and Mylar blankets are way more expensive.

i used a reflective white paint

yea survival blankets or them ice covers for car windows should both work, and maylor is for sure to prefer over flat white, my light meter show way more light from maylor then flat white



and yes I got more maylor for the other wall, 10$ seems to be wort it, even tho it kind a trap`s heat as much as light.

the blankets suck way to thin they rip easy just get some flat white paint

also-

the shiny is just a thin veneer, on clear plastic. the coating is very vulnerable to moisture. it was designed for space use by nasa, whereas there is no moisture.

after about thirty days, it will look as thought the mylar has had water thrown on it, with big splotchy looking stains. at that point it's less reflective than tin foil. use a good flat primer/ sealer paint. make sure it contains titanium dioxide. 80-85% reflective.

searcht the forum. many tests and proofs have been made as to this.

In my experience antything shiny or metal will add heat to my grow area......imo this is why I would recommend using .GL.peace

Depends on the type of survival blanket. Some have the same on both sides, some have a more flat vs. shiny side.

Hi Slipon,
I have the same mylar material. The one with the small bubbles. My question is, can I use it to make a reflector with it? I mean can I glue it to some metal plate? Will it melt under a 250 HPS? I am in search of a reflector but IDK if a 20$ U shaped reflector is ok or I should get a 60-70$ A Wing reflector. I use a 250 HPS. I will never grow more than 4 plants I think.

i have some of that shiny matierial with foamy stuff on the other side of it,is that stuff mylar! this is used for layin floorboards i think.
would that work as reflector without burning,also do i leave the foam on the other side or peal it all off so its more like a wrapping paper?
peace

help is much appreciated!
