Physical Appearance
It was sub-level, presumably below the basement. Lionel Luthor once referred to it as a redundant storage area.
Early History
In 2001, Earl Jenkins was assigned to that area when he worked at the plant as a janitor. Earl described an enormous cornfield being sprayed with a green mist— certainly meteor rock-infused fertilizer. He was caught in an explosion, and tiny particles of kryptonite penetrated his skin, causing him to suffer from random, violent seizures as his body tried to push the poison out of his skin.
Season One
secret elevator entrance to Level Three
Along with Lex Luthor and Clark Kent, Earl finally found what was left of Level 3, but there were no clues remaining regarding the experiments that injured Earl.
A few years later, Lionel still maintained Level Three experiments, such as cloning.

Level 33.1
After Lionel was imprisoned, Lex took control of the operation. He moved the headquarters from the Smallville Fertilizer plant to a secret level in the LuthorCorp Plaza skyscraper in Metropolis, between Floors 33 and 34, and changed the name to Level 33.1.
Trivia
- John Novack (Jed McNally) and Yee Jee Tso (Nick Yang) both appeared in an episode, of the BBC series Doctor Who (1996 film). Novack played the E.R. doctor and Tso played Chang Lee (The Doctor's companion).
Notes
- At some point, it's mentioned that there are/were Level Three facilities in Gotham City, Coast City and Bludhaven.[1]
- Level 3 was basically Lionel's own 33.1 before Lex took over and making and changing it into his own.
