Haha were I come from you won't find much people growing veggies in that kind of setup.
Jokes aside (despite it is also a fact) I really like pretty much every project that enables people in the city, without a garden access, to grow their own food. And this looks like it is for sure a high class setup (I wasn't able to find a price but would guess we are talking $1,000 plus here). What I'm trying to say with this is that yeah sure this is pretty much one of the best ways but if you are really into growing your own food there are a ton of way cheaper ways with just minimal more effort.
