By... what, a half hour? My family is Puerto Rican, the days don't change all that much. In any event, here, this is my favorite tool to use for such things. Daylight Hours Explorer
Just find your latitude, work the dates, and you can get the daylight hours sorted out.
Hehheh, I just fiddled with it, dropped the latitude to approximately Costa Rica, and it looks like I was right. It's a difference of about a half an hour, give or take a few minutes.
I lived in Florida most my life and the amount of sunlight doesn't change as much compared to the New York area I'm in now. Costa Rica has almost no change in amount of light year round so you can grow basically whenever. Just go with a sativa dom strain, like Haze or Durban Poison, something with at least 60% sativa, but I would go with a 80% sativa. If you grow a heavy indica, it might not even veg.
