The Rainforest Biome is the larger of Eden's two covered biomes. 100 meters wide, 200 metres long and 55 metres high, with an area of
15,590 square metres, it is the world's biggest greenhouse. The Rainforest
Biome contains tropical plants such as banana trees, coffee, rubber and
giant bamboo. The other biomes are the smaller Mediterranean Biome and the
The biomes are constructed from a tubular steel frame with
transparent panels manufactured from a plastic called EFTE (Ethylene TetrafluoroEthylene).
The panels are transparent to UV light and have a triple-membrane structure
which provides them with excellent heat insulation properties.
The temperature in the Rainforest Biome ranges from 18 to
35Â°C, humidity is maintained by a network of misting sprays and a waterfall.
The climate is regulated using computerised systems, but relies on the natural
properties of the environment such as the rear cliff wall which absorbs
heat from the sun during the day and releases it at night. The plants themselves
also help control the environment, releasing moisture to cool the air when
it gets too warm.
This is the view of the Eden Project you get on
arrival, having passed through the Visitor Centre at the entrance.
Eden's Mediterranean Biome is 65 metres wide, 135 metres long
