Love your pond !    I currently work at an in-Tucson job 4 full days a week myself.  I am practicing permaculture ideas (on weekends) at the house we have leased because there is room (and three other people to help ( husband and two grown sons ) for projects) - (I figure can bring the experience where ever I go, and the sons will continue the pojects)  Currently we are doing setup a modified hydroponic garden for the hot Sonoran Desert Summer. Here is a link to a youtube channel to help you with your questions about a lot of things - including building with earth-bags :>>>>.
