Thank you guys. I think to start, I'll set one half w/HPS and one with out. Leave my current HPS/Flouro system alone just replace the basil. That way I can get a 3way comparison. What will be nice is the flexibility of the new system. I could grow 24hr PAD SL&NL on one side w/HB in the center. While the other side is spinnin up the KC36 and EMH with flouro enhanced HPS 12/12. Possibilities are endless. If I cared about yield I'd could blast'em all w/more HPS time. It'll be cool. Thanks everyone. I need to get away from the damn internet or I'll never get anything done. Lord knows if this works well, that Northern Lights might keep me from ever getting anything accomplished:jointsmile:
