Yes if they are white light especially 6000k, 5000k, etc. To an extent (generalization) it is all about photons. Another generalization is watts per sf. Add all of your wattage and divide by the sf of your area. 35 watts is really good. I'm at 43.75 which may actually be high. At the moment I still have room to adjust my lights higher height wise. If I see any taco leaves I raise my lights. Just to be clear there is nothing wrong with the King. It will grow good bud and many Growers have had and are having great success with that type of light. I was trying to get you off on the best foot. I really look forward to seeing what you do in the future. Great job so far!
