OK. So I finally got everything set up. I purchased a 54 watt led grow light from Amazon and that is what I'm using. My main concern is that the light is very concentrated in the middle of the screen. I moved it about 6 inches from the screen to try and widen the coverage but it did very little. Do you think I need some sort of diffuser on the light to get more even coverage or do you think this will work? Any other comments are welcome. Thanks.
