Growing our own hops?

While perusing the internet, I came across this on ThinkGeek.

It's a little greenhouse for growing your own hops, wheat, and barley. Cool! It probably doesn't make a whole lot, nor is it guaranteed to grow, but why not give it a shot. We can add it to our next creation to give it a kick of pure beautiful freshness.
