I've set up some simple low maintenance Hydroponic/aquaponic systems. Using sifted Arborist woodchips as a growing medium and inexpensive components, I have reduced labor and input making my gardening easy. Adding water features to my garden has improved the micro-climate. The plants around the ponds benefit from the extra humidity and the water moderates the temperature.
