Lab 4005 was a lab aboard the USS Cerritos that contained plants.
While performing anomaly consolidation duty in 2381, Ensigns Beckett Mariner, Sam Rutherford, and D'Vana Tendi went into this lab, which contained plants of various species. One such plant was smelled by Tendi, who invited Mariner to smell its flower, only for the plant to spray thorns in her face that had to be pulled out by Tendi. (LD: "The Spy Humongous")
This lab contained a single-tube version of the Tucker tubes (aka 'Zabrucky-Turnbow Drive', aka 'The Most Important Device in the Universe'), to the left of the doorway upon entry. [1]
