I think this sums it up:
"3/ The Procedure
« Back To Top
To farm the Alazhi you must satsify these conditions:
* The owner of the Farm must be a faction.
* The Farm must be powered.
* If the owner is a Medical faction then there must be a Manager and an Operator (any faction or character).
If the owner is not a Medical faction then the Manager must be a Medical faction and the Operator a member of that faction.
To process Alazhi you need to be in command of at least 1 Bacta Engineer NPC. In the 'actions' part of the command room, there's a button 'process'. Here, you assign at least 1 NPC to the facility, choose which piles to process, and after agreeing with an estimate of the procedure, start processing. The time it will take and the money it will consume will all be displayed in the estimate. In the process screen you can also see past Process reports. Once you're processing, only an ETA and the reports are available.
When the processing is done, you'll receive a message from your NPC crew with a report. The source piles will be deleted from the database and the Bacta piles will be created where there is room. "
