irrigation system for hydroponics.

[Dennis]

Ron, i have a couple of questions. First of all, I was wondering if it is possible to use an irrigation system for hydroponics. In other words my idea is to hook up a fertilizer mixer/dispenser to the water outlet and let the mixture flood the 9 plant garden setup. I plan on attaching a timer so that everything is controlled. When draining the system is it necessary to recycle the mixture or would discarding it cost too much money?
