Really fun and entertaining. You sign up behind Soarin desk, and tours are scheduled throughout day. Like Jedi academy, sign up earlier than later, or you will pay and have to return way later. It is a 45 minute walking tour. You start in the lab and they talk about the different research projects. The CM answers questions. Then, you walk into the Land Area ride itself in different parts of the greenhouse and fish farm room. No touching plants, but take pictures and ask questions. They explain about the different types of growing systems in more detail, taste sample cucumbers grown there, and you do get to hold the fluted pumpkin and a coconut. The group each receives fish food in your hands (if you want) and you throw it into the Tilapia tank. I'm sure the tour changes as the different crops grow. They explain about how long it takes stuff to grow. If you like the Living with the Land ride, you will enjoy this tour.
