Hey Joe. Greetings from Boriken!
Right there with you man! I live in Puerto Rico, really close to the coast.. so advice on just tropical region is good but it would be awsome to get something a little bit more specific. I'm just starting my project, implementing techniques for rainwater harvesting and water management in the house. Gardening for supplying my food truck with fresh veggies.. just looking for self sufficiency and freedom.
Anything in particular that you need help with?
(this was my first post!) thanks!
ps: there's this book that was released here in Puerto Rico which is called "La Tierra Viva" Manual de Agricultura Ecologica, its an organic gardening book designed for Puerto Rico but I guess it would work for you!
