You can if you want. Add UVB for best results.I agree, ran 400W HPS for a bit and my 315W is stronger than that. I would have to say around 500W HPS, with less heat.
Since I can rotate my plants as I did in my G13 grow with my Old SS 400W LED I am thinking of adding it in with this grow.
I would like to add more UV towards the end of my grow. I know this is a silly question, my long time friend, but do you have any thoughts on adding UV?
