Fastbreeder Plants, also referred to as Nests by both the Galactic Republic and Imperial military, were essentially compact manufacturing facilities. These were designed by Lema Xandret with the purpose of quickly generating her innovative droid model, known as the fastbreeder.
These silver, waist-high cylindrical structures, the fastbreeder plants, built new droids by drawing upon resources found in their immediate vicinity. This was achieved through the deployment of slender, silver tendrils that extended into the surrounding area, extracting minerals and directing them back into the plant. These tendrils possessed the ability to connect to nearby electrical systems, significantly accelerating the manufacturing process. Subsequently, new droids were put together within the nest and then deployed.
The fastbreeder plants also had the capacity to replicate themselves, creating new plants. However, their reproductive ability appeared to be capped at a maximum of two additional units.
