Cannabis testing is super inconsistent to date. The Ring Test conducted by O'Shaughnnessey's shows what I mean. Also, the second chapter in the Cannabis Encyclopedia has much information about the inconsistencies of testing. I chose Alpha-Cat TLC tests from France because the owner is a career scientist and has the most consistent test. They test for cannabinoid content rather than effects or fragrance. The two latter tests are much more complex and effects could be considered subjective.
@Horse Badorities I see you agree with the subjective part above and you also brought up the point of "every grow is different" so true!
