Greenhouse Tours Guided walking tour in The Land at Epcot; beginning December 10, 1993. Superseded Tomorrow’s Harvest tours. Guides who are usually agricultural graduate students take small groups behind the scenes in the attraction, explaining hydroponics, aquaculture, drip irrigation, and other agricultural concepts, and are available to answer questions one might have posed while riding Living with the Land. The name changed to Behind the Seeds Tour in September 1996.
