Best reflective material

G`day to all from Australia, i love this site have just joined. I`m setting up a room for some THC Bomb seedlings i have , i`m looking for the best reflective material for the room. Is Mylar mirror sheeting any good,i heard it adsorbs the light but on watching some you tube set-ups they recomend it. Any help would be great. Happy smokin

yes mylar is very effective im not expert but i know most growers use, just stay away from aluminum foil.

X2 mylar works fine

thanx mate i will go ahead with using it , and now its been mentioned its aluminium foil that absorbs the light. Will put up some pics soon, still trying to work out how to use this site
