I just got a ward closet and the whole thing is white inside and out. Should i leave it like that or use mylar. I will be growing 4-6 plants under 400w hps/mh. I will use mylar if its going to work a lot better then white. I just dont want to slap this stuff all over the new closet if not needed. What do you guys think?
If it didn't help they wouldn't sell it. That being said flat white paint is pretty reflective and you're growing in a small space you don't "need" to do it.
I like flat white paint. If that is not possible I try and use black/white poly. mylar is cool as shit looking though when you get it all up and flat inside one of those though.
