I got a 400 watt MH given to me as well, all this talk bout Hps lights MH was used to grow long b4 they were used, hightech, n more money. Use what u got and heres a pic of my setup, 7$ light sockets I took the hoods off, 2 way socket, 4 for 10 $ 26 watt light bulbs, flour, n 1 40 watt flour. I use these for the vegg as u can see and when I start to flower on March 19, I will plug in my big daddy MH ;0) If u got it the $, be smart and keep it unless u plan on going big career wise ;0)
