IMHO white poster board will work but mylar would be ten times better. You can also try using flat white paint if that is an option.

Last summer I actually had half white (semigloss) t'other half mylar. The plants on the white side of room healthier, bigger. Didn't think about it much till I read this thread.

Well u cannot argue with physics and fact... mylar reflects light better then any other known substance.... the problem is (imo) it gets dirty half easy... I have no problems with it getting dirty... I never touch my walls or anything... and i have intake and exhaust filters... so no dust in the room what so ever basically. Black/White Poly is the best per value... it is tough stuff.. and can be wiped down easily if it gets dirty.
