Don't be foolish and let these cats come to your grow location, take the samples to them or drop off at a pickup center...that's how rippers operate...even though your in a med state now, trust no one..rippers will get you faster than the cops...the gear that it takes cost about $250,000k on the low end, the better gear is around a million bucks to setup and operate and requires a completely sterile enviroment to conduct, I would watch out for someone in an old converted food truck showin up to test my gear..
What kind of test? liquid or gas chromograph? gas is a total waste IMO because they heat the sample for testing and you don't get the inactive THC content at all only active and basically the test turns all THC active thru the testing process..most testing facilities have about a year learning curve to figure everything out...I have done hundreds of test now on every variation of product you could imagine and it is a process to get it all right or even close to right..I spent a few days right beside the scientist dude with the testing gear and saw all the different variations and how subjective it actually is, hard to believe that the hard science of it all is so subjective and not so objective, but it is
It wound up being a kind of novelty out here in CO, there were 4 or 5 different testing facilities goin at each other. A few were using the testing process to secure methods and produce products of their own to compete in the despensary racket directly against the people they were testing for...you can also scew the test to bolster one depsnsaries reputation over another, whether acurate or not, also the regulation for a testing facility is way tricky with the state, you basically an unliscensed faclity with a pile of other peoples weed sittin around which you are liable for and really have no protection for..Alot of people will get a bunch of test, pick the highest one and use that test from then on out, never testing again and makin you think that they are batch testing all the time but it might be test numbers from one badass run a year ago..it may suck now but hey, they got some good numbers at one point..
Just be careful and do your due diligence before you get to into it to deep and put to much weight into the actual test numbers...I have 50+ test here that are absolutely worthless due to faulty testing methodology
