You should be fine I think. Don't bother worrying about it though, its not like worrying will turn the power back on, it will only make you upset. If you really want to do something about you could find an old bike/ exercise bike and hook it up to a generator and hook the generator to some CFLs. Then you could hire a cyclist to light your plants. Pick a big cyclist though, look for a clydesdale category road cyclist. Those big guys can easily sustain 250 watts for an extended period of time. Little guys might be faster on the road, but thats because they're more aerodynamic and have greater output versus mass while the big guys produce more watts overall.
