If I could grow the things... I struggle to get them watered properly.
Practically, though, I'm out in some fairly high desert, and I have to pump water for irrigation out of a deep well. I can certainly do it, but I'm looking for something of a bit more "geologic scale" sequestration, if it's possible.
I'm actually planning to get a backhoe for a couple years to build a large basalt greenhouse, then do aquaponics - combine growing fish and plants in something that removes most of the downsides of aquaculture and hydroponics. Done properly, it's a synthetic pond ecosystem that doesn't require flushing the water ever.
