I have no idea how strict the laws are in PR. It's your hide, so do what you want. The problem is an old acquaintance of mine named Mr. Murphy. You may know him as well. He has a habit of showing up when you don't want or expect him to, know what I mean? I was stationed in Italy, which isn't that different than PR, so I know what you mean about people building and abandoning houses. I've been to PR a few times so I'm a little bit familiar with the culture. It's much more laid back (except the driving part
). I brought an ounce with me to PR when I went down there for a class. I was amazed how easy it was to smuggle in. This was pre 9/11 though, but I digress. Back to Mr. Murphy for a minute. 8 years is certainly a long time for a property to sit vacant. That doesn't mean that someone isn't going to decide to do something with it at any time. And as my friend Mr. Murphy will tell you, they will probably decide to do something with it right about the time you're going to water or check on your plants. I know you say you're going to do it at night but that's no guarantee. I used to be a guerilla grower and have seen cops stake out a plot for weeks waiting for the grower to show up to tend his crop. They usually waited until right before harvest to begin staking out the grow. One plant is probably not worth anybody's time so you've got that going for you. Just be careful and use commone sense. If something doesn't feel right, you need to be able to walk away from that plant. One plant isn't worth getting pinched. Can you do that?
