I am currently using Those Gray Lowe Buckets Ive read that they are light proof and have also read that they arent! has anyone had problems with these buckets? i am doing rdwc...also i would love advice on what to reflective material works best (Mylar, Reflectix, etc.) and is the easiest to cover the buckets in?! also any techniques to make it look as clean as possible will be greatly appreciated! thanks all!
