I am just wondering who all has tried these the local hydro store gave me one to try out a while ago I noticed it did get rid of the bright spot in the center of my light and made even brighter spots around the entire edge when I was using it with my hidhut.com deluxe reflector with mh bulb. I am just curious what others think of them that have used them and what kind of reflectors people are using them with. This was my first grow and I just threw it in there because I had it. I am almost in flower now and wondering if it would be worth getting a couple more for the mh or if it would just be a waist of money. ok I think I put this in the wrong section if so can some one move it to where it should be.
