I think im just gonna can my grow.. out of 4 plants, 2 are males and 2 not sure yet. If I would have known this, I probably wouldn't of spent the $$ on all my gear. I don't have any buddies that are electricians and don't wanna mess with any wiring. Thanks for the info.
BTW my "heavy duty" timer says its total ratings are
15a general purpose
15a resistive
1250w tungsten
1/3 hp
Wait, there's no reason to mess with any wiring. Running a 220 line is just one option. You can use timers on 120 just fine. As I said, I'm running a 1kw on a $10 Brinks timer from wal mart with absolutely zero issues. Even if I were to switch it out every grow for safety purposes (I don't), that's cheap.
Just be aware of the potential, and make sure you monitor your timer carefully.
Certainly don't give up on growing, re-wiring is not a must by a very long shot.
