Dry and cure flower until it is in its final sellable form.
Divide final product into ten pound batches by strain. The State currently recognizes five strains: sativa, indica, afghanica, ruderalis, or hybrid varieties.
Assign batch numbers. These are internally generated numbers by the grower.
Example: Batch ID: GG.123456
Collect seven grams from each batch from randomized locations of your sample.
Visually divide batch into 9 quadrants. Take .78 grams per quadrant to collect the seven grams in a randomized manner.
Submit to the laboratory with batch number(s) you have assigned so it is notated on your Certificate of Analysis.
