Abstract: A production plan for producing cannabis in a facility comprising a building module comprising five growth chambers of substantially equal size and a GMP processing area comprises a system of concurrent cyclic processes (SCCPs) for carrying out cannabis processing steps of hardening; growth, wet hanging, in-process quality control, transfer to GMP drying; in-process quality control; trimming; curing, and grading/packing. The SCCPs is based upon a minimum cycle time (MCT) defined as MCT=FP/5, where FP is a flowering period for a selected cannabis species, and 5 is the number of growth chambers in which the cannabis species will be grown. A cannabis production facility comprises a building module having five growth chambers of substantially equal size, a GMP processing area and a production plan. A method is provided for designing a cannabis production facility for assessing the feasibility thereof at a concept stage.
