Hi, i am pretty new to this site and i am hoping to get more into this community. I figured i would start with a question. If i put a blue screen(plastic, used for stage lights) over my 400w Mh Light fixture, would that improve the vegetative growth rate? has anyone ever tried anything like this? I know the plants need a lot of light in the blue spectrum, but my knowledge is very limited in this field, i have always done outdoors. If im getting anything wrong, or im in the wrong place please let me know.
