Last year, I had a small drip irrigation system on a timer for watering my container garden. This year I would like to do the same thing, but will need some different hardware since I am increasing square footage considerably. After some extensive online research, I found a few manufacturers of drip-line, each with different spacing and flow rates. I decided to go with 12 inch spacing (one per square) with .6 gph per emitter which I found on eBay for quite a deal. Ordered it today, see what it looks like in 7-10 days when it arrives.
