My wife brings home lettuce from the hydroponics professor's test greenhouse every now and then, it's really good. (One of the varieties she got from him was so good I found out what the seed was and ordered it for my Aerogarden, where it grows very nicely.)
His tomatoes are incredible, big and tasty, and the plants are like 10 feet tall and keep getting longer as they grow, so the non-bearing part of the vine stretches several feet off to the side.
