I usually just smoke it and see if I melt into the couch :joy:

@Carpenter and @SilvaBack203 do testing :smiley: maybe they can help

You could give me some and I’d tell you if it had a lot of THC or a little.

There seriously are a few thc testers on amazon.

I usually do the same, take a few hit’s and see how how hard it hits back… :joy: :stuck_out_tongue_closed_eyes:
TCheck has a device that tests the total cannabinoids with the THC being dominant. They don’t have a device yet that will check CBD though. Only THC
Raw flower(non-decarbinated)
Decarbed flower
Infusion
Winterized concentrate and maybe a few more! IMO
@Turtlehead hope this helps. You do need the expansion pac to check raw flower if you decide to purchase it.

I have several taste testers in person as all weed tastes exactly the same for me. They do an amazing job for me and I don’t have to guess.

It’s not all about thc. Thc works with other cannabinoids. A lower thc can sometimes get you higher than a higher thc depending on those other cannabinoids.

The tcheck2 tests CBD if it is a CBD dominant strain. But it can’t really give the kind of breakdown a real lab test would.

I don’t have a super helpful thought on how to test flower with a professional lab though.

Tcheck is + - 15%

15%×- isn’t that like close to Tarot Cards???

I think it’s actually + or - about 3% for flower testing. Close enough for my purposes. It’s either “over 20%” or not.

I test potency/quality by pressing 7g of flower if I get 1.5g or more of rosin its good. Less than a gram its just ok or crap. May not be accurate but it a pretty good indicator.

I had read that on another post somewhere here. Since you said that i decided to do some research. Tchech is accurate to ± 3% of an hlpc which is accurate to within ± 4.3%. That means to me it is accurate with in 7.3%. So in other words you are correct close enough.
Just goes to show always do your own research. Thank you for the info.

That’s a valuable correction to have. I have tested a few strains without ever really getting up over ~11% THC, which could mean as high as ~18%. But that all goes also to @Carpenter ’s point which is only testing THC doesn’t equate to potency. I think @JaneQP and @Mr_Wormwood can probably verify but seems highly unlikely that Frosted Jungle - the strain that tested right around 11% - is “weak” from a smoking standpoint.

Absolutely. I learned from @Tylersays that the things I need to know can be good to get the gist from the forum but the real nerdy in-depth knowledge is often lurking with other sources. Thank you for doing the legwork on the tCheck research and following back up with us!

Honestly that’s not a terrible practice either. I would do a QWET wash with trim and the yield from the trim usually tells me enough. At this point though it’s all blended together in a 5gal grove bag so I have no hope of figuring out which one of 20 plants was the best yielder :joy: pressing probably makes more sense.

Excellent break down @Graysin
I have the Tcheck2 and I believe your right about the CBD being dominant. My wife gave it to me because it wasn’t suitable for CBD. Info from the company!
Does what I need it to do for myself. And yes don’t take anyone’s word for anything always do your own research :face_with_monocle:. Plus you gain knowledge a win win! :love_you_gesture:

Having spent many years in laboratories - analytical uncertainty is a real thing. The messier the matrix the more uncertainty due to interference. If you painstakingly go through error analysis of every step in the process from purity of standards, pipettes, balances, etc. it adds up.

I never understood why defense lawyers on DUI cases didn’t grab this concept to argue that the client may have actually been below the limit.

Laboratory QC has acceptable limits for QC that vary from, 10-50% as acceptable depending on the analyte of interest.

Likely has to do with the fact that getting a law degree does not require much lab analytics… Just a thought.
