Guides

Plain guides to cannabis lab sheets, labels and batches: what the numbers mean, what they don't, and how to compare jars honestly.

• How to read a lab sheet (COA)
  What each section of a cannabis Certificate of Analysis is, which numbers matter when you are choosing a jar, what total terpenes does and does not tell you, and how to spot an old batch.
• What the numbers on a Pennsylvania cannabis label mean
  THCa versus total THC, the mg/g trap, lot numbers and the QR code, and what is specific to Pennsylvania's medical-only program, explained line by line.
• Why a strain name tells you nothing about the batch
  The same strain name on two jars does not mean the same plant, the same lab sheet or the same experience. Why StashLog logs jars instead of strains, and scores on the terpenes you can actually measure.
