I have really fucked some things up over the years because of not thinking things completely through. What I suggest here is to just to always look at the things that your mind does not instantly notice. It may sound like some wisdom but it is merely being practical and pragmatic. In other words break things down to there 'base elements' and try to really grasp the relation between one 'base element' and another. The stuff that you are doing is really cool and all but really what is going on is just that you are trying to create an 'un-natural' environment for some very 'natural' organisms. The stuff that I do in nature is pretty expansive and I (like yourself) often see the 'results' in a very fundamental way...so in other words shit dies or it lives. It is not so much some great burden to bear but an obligation to foster life. There is always going to be what I call a 'learning swerve' there because we ourselves are not excluded from the process...so in other words be easy on yourself and embrace your failures just as much (if not more) than embracing your accomplishments. That is my two cents and I hope it helps.
