Arduino-based, urban aquaponics in Oakland

Is water used by hydroponics really "used"? As far as I can tell, aside from "loss" to evaporation and water used in part of the mass that makes up the fruit you send out, nothing should really be wasting water.

It seems likely that lost water due to evaporation with this type of setup should be a great deal less than water lost with traditional farming (spraying water with things like center-pivot irrigation machines should cause much more evaporation. I mean, come on... http://upload.wikimedia.org/wikipedia/commons/6/6e/Irrigatio...), and water lost through fruit mass is irrelevant.

Yes, my point is that Hydroponics use very little water while traditional agriculture uses a large amount. If water were actually as expensive as it's scarcity, Hydroponics would be more competitive.

Ah yes, I see. That is a good point.
