Thanks, that doesn't sound too hard....
For the love of god make sure you turn it off first! Some of those heaters get hot as hell and I'd hate to see you melt your garden hose and burn the shit out of yourself.
Without power some sort of cooking source will be needed, and a fuel source to power it. Some things can be warmed in the hot Florida sun for free.
Thats a lot of water. Depending on where in fl u are you might want to look into a well. The water table in my yard is 5' down. There are places around here that are 3' down
Storing/using water in that way starts to become expensive. You might want to look into a filtration system or larger sized containers....gallon or a 5 gallon delivery
Look up a "solar oven". Think parked car in the hot summer sun magnified.
As for what I have for provisions I'm not 100% sure... I know I got a large barrel of dry pasta and another of dry rice then one more full of mixed beans and a shelf full of pasta sauce not including what I got in my freezer and cupboards.
If I can get everything finished before the snow flies I should also have a smoker built for making venison jerky and as for water I have a well with both a hand pump and an electric pump not including the three ponds out back.
I know on my land that there's edible mushrooms, fiddle heads, black berries, goose berries, strawberries, winter mint, asparagus, cat tails, and around nine apple trees not including the nut bearing trees.
Lots of hunting and fishing around these parts as well.
