I found a couple south of us who have very similar goals as we do. They have chickens and a garden and are trying to eat fresh and buy local. They make water collection barrells and Aquoponics barrells. I purched one of there water barrells and set it up the other day and of course since then we have had no rain to speak of. Today it sprinkled a little but not enough to even cover the bottom of the barrell.
Next week I pick up my Aquapomics barrells. I can't wait!!
