Growing more food per acre in an indoor hydroponic farm is a reality today. The problem is your romaine from that hydro farm down the road is $3.99, and from the traditional farm shipped across the country is $1.99. Lights are a big part of the equation. Most plants need 10+ hours of sunlight a day, so even if you put the plants on a rotisserie you still have to supplement with artificial light ($$$). The amount of water and land you save is immense, however, the water and land cost of putting a farm in an urban area counters that.

Pollination is easy - bees. Even basement/garage growers will use bees to pollinate. That said, you don't need bees in this example as you never want lettuce (or any leafy green) to flower. You can control the flowering with reduced temp and different light temperatures, too. In tomato/pepper/fruiting plants, you'll need manual pollination or a beehive in your hydro-warehouse.

Re: super-organic - Most hydroponic growing is not organic. By nature of adding nutrients (fertilizer, salts, ph adjustments) that replace what is found in soil means hydroponics is traditionally not organic. There are organic hydroponics going on (I am not aware of a large-scale one) and they are NOT clean nor bug free, given the nature of making organic nutrients (they smell like shit, really, as most are compost or something-rotting-based).
