Ok so I decided to go with 250w but by doing so ive been looking around and its been hard to find a grow kit that has the whole bundle of a 250w HPS / MH but I've managed to find one that will ship in canada http://ctcauto888.trustpass.alibaba....ight_250w.html can someone tell me why the ballast has wires coming like actual copper wires out of it compared to all the other ones?
