new grow room suggestions please

hi everyone i have a simple question to ask.what would be a good material or fabric i could use to block light from escaping my closet that would be somewhat fire safe.im gonna be running a 400 watt hps with proper ventalation etc. i just dont want to get a fabric that could possibly start a fire got forbid something happens.thanks your time guys

go get some blackout material. It is heat retardant, heavy, and is white, so will reflect light.
I believe you can buy it by the yard, and it comes in 50 inch wide rolls.

Good luck dude!

Cheaper option... Black Duct Tape... Solid stuff

thanks i think im gonna try the black out material.will post pics of grow room when complete.
