I know now that im going HQI with my Nano. My question is what is the best set up for my Nano that is only 18inches in width. I am currently looking at the Current Sunpod 20inch 70W with luner lights or the JBJ Viper 70W without Luner lights. Im not a big fan of JBJ only because Im in search of lighting after owning a Nano for only 12 months. Any suggestions from nano owners with HQI?
