Yes very big Aligators, ive seen ten foot bulls.
I dont worry much about them, only during the rut season (mating season).
I do worry about Cottonmouth snakes which are very deadly. They like to hide in the trees and swoop down unanounced. I hate it because by nature I am always looking down and not looking up when.
Also the deadly Moccasin,Rattler and Coral snakes are common in this area. Gotta be careful growing in these woods. But its worth having four seasons of the year to grow outdoors I suppose.
It must be a pleasure to grow in a hidden tropical island Pure sativas and sativa dominant strains are the best choices, indicas would easily mold.
Best wishes and be careful with snakes!
