Maximizing space to grow food.

C:  I really love how he incorporates the trickle down strawberry watering system into this setup of his.  Can certainly see the benefits of building upward instead of outward when space is limited.

Something like this is my dream.

I would love to get a small house somewhere and have a backyard farm with solar power as they have in this video.  Would perhaps take it a few steps further with aquaponics. That is raising fish in series with the plants.
