How to test THC levels. (POTENCY)

[joe_guy]

get a wicca box or what ever a quarter ounce of dank and shake the shit out of it. for days and days tell it has appeared to have lost all its keif. then weight the amount of keif compared to the original weight so if its .7 its 10% thc, pretty gettho but waht ever man.

Kief is not THC. At best it's about 50%.

The ONLY WAY is to have a lab test it.

what they do is they take a measured amount of dry bud, say ten grams for example, then they chemically extract all the THC using a solvent such as acetone, then they refine it to remove all the impurities then they weigh the amount of pure THC and compare it to the weight of the dry bud.
so if you had 10 grams of dry bud and after extraction your left with 1 gram of THC your weed would be 10% THC

No, that's NOT what they do. They use gas chromatography. Nothing else will give an accurate reading.

God the BS information people keep putting out here as if they know what they are talking about gets me pissed off sometimes. If you're not sure something is a fact you shouldn't post it.

The method you propose is very crude and will not give any kind of accurate reading.

Sorry for my tone. I wasn't flaming you. I just get agitated sometimes at bad information. I'm sure you weren't saying it to purposely mislead people.

One of the reasons I got agitated was a lot of seedbanks quote percentages using exactly that same flawed method.

No matter what solvent is used there are other compounds that get dissolved as well. Other cannabinoids, various terpenes, and other organic molecules.

I guess if you wanted to make a rough guess you could make a very high quaility solvent based concentrate then assume that 80% of it is THC and other cannabinoids, but it would really just be an educated guess.

yea mate your right even with refining there is still a small amount of impurities but if your just wanting an idea at home it does give a a (rough) number to work from, you could even factor in a 20% margin for error against impurities (which is a bit on the high end but just to be safe) in the final product, P

look at the weed under it. you will be able to see if it covered in crystals. or mold. or nothing at all.
Also you can tell what colour they are. Good to know sense the colours tell you what type of high your going to be getting.

Higher potency isn't = more trichomes. High potency = lots of high-grade cannabinoids, whether they're distributed in invisibly few trichomes on the bud or invisibly few of many trichomes on the bud. It is not impossible for a bud to be covered in trichs and still be schwag. It is also very possible for bud to have almost no trichs and still be dank as hell. At least in theory, that is - don't know if it's ever happened.

Also, the color has nothing to do with the effect - it's not cannabinoids that are causing these colors and the colors aren't affecting the production of each individual cannabinoid type.

Exactly. Plus rep for you good Sir.

Seriously! He could have at least passed it to me for a hit or two!

note i did mention its the gettho wayy of doing it.

What I think is, when hash is made that other 80% of whatever has been filtered away, and then that 20% is converted to 100% because, the other chemicals or w/e have been taken away from the "PIE" (just ignore if that is possible or not), but, the THC has not increased in potency, it has just be concentrated. So you have now 2 percentages? One is the THC potency and the other is the THC concentration %. The potency % I guess would produce better quality concentrations.

I have nothing to back anything I just said up, Im just going on what Ive been thinking about

Tell me if that makes sense.

Can someone tell me if Im crazy pills or something. Im really interested in this subject, but IDK anything factual about it.

No matter how good the bud and how skilled the maker, no hash or hash oil is ever 100% cannabinoids. That's been said already in other posts.
