Would the CCs and the dispensaries out there use that service?

I don't know but I don't think I'll be sleeping tonight with all the ideas I got in my head that I can do with this thing. With the access to the people I have every day even if I did two tests per day this would make a nice little income and the thing would be paid off fast, well that depends on the maintenance intervals/requirements. With the pesticide module holly cow could I stir up some trouble lol I have someone who is willing to pony up the money if I create a proper plan for the business.

Can't believe I didn't look into this earlier I always thought this required serious brain work and the machines were super expensive.

Ill do some research for the next few days and see what are the running and maintenance costs for this machine and see if its a viable business idea.

As someone who has worked in a lab, that was confusing for me...

Which particular one was confusing?

It might be a YouTube problem, but I would avoid any lab that allows itself to be presented to the world as:
  • not wearing PPE
  • using a fumehood with the sash too high
  • only sampling a single bud
  • not homogenising the bud
  • not shaking the sample during extraction (I presume the incubator does not shake - it might, but I saw no mention of it)
  • using a manual injection instead of an automated injection; Hamilton syringes are good, but human error makes them sloppy
...and that was from one video. Also, I am intrigued to know what that phone call in the background was about.

I would be interested to see the validation stats on their method. My guess is that you get what you pay for.

Not just in the testing you receive but the equipment used for testing. GC seems to be much more affordable than HPLC testing equipment, which leads me to believe that is why LP's are using it. Regardless of the lack of accuracy in it's result.

I suppose what I should have said was his explanation was confusing to me so someone without a tech background or lab training might think that this may be easy to do. In my mind for someone without a background, it would be much easier and probably more accurate to have less steps to follow, than subtract that derivative from this whole sample....one calibration per cannabinoid Bing bag boom assay done! Too many years in the mine lab I guess. I still would like to know what the standard is that being used to calibrate against. Are you in a lab magenta?

How inarticulate is GC vs HPLC? Its it 98% accurate than for a consumer grade test that wont matter, hell just the pesticide test would be worth. I've had this idea a few years back but no way could I afford a new machine. I guess only way to test would be to pay for a HPLC test and send a sample from the same bud and get a GC test done on that machine.

that's the same thing i was wondering, and also, how accessible they are for the home enthusiast..

Found this little break down http://www.freedomisgreen.com/cannabis-laboratories-the-testing-landscape-in-america/

So GC can't detect THC-a but for the most part will show accurate level of THC/CBD in dry bud, but the levels might/will be higher if you are going to process the cannabis further using heat which will activate the THC-a and CBD-a into active TCH/CBD.

So if I'm upfront with the testing method and what the test will reveal and I price it accordingly this is still doable and get accurate results.
