I agree with Ken. Emmanuel attached is some info for you to try and practice. Its a rainy season so there should be many worms out there. Just try it, you may love it and never stop. You dont have to buy equipment just form small raised beds and provide some worms , feed and the mulch, this has been done in Cuba for years.
