Thank you @pop22 Good info there. I never noticed any significant difference but I am sure I didn't quite do it right either!

I tried to make the point on RIU that you can't just crank up a new light to 1000+ppfd and expect max growth, you need increased nutrients AND more CO2. 1000 ppfd won't do much more than 600-700ppfd will without CO2
