What about that Jedi Kush Cali connection has out testing, it says 40 somthing percent?
Highest THC Content?

pineapple chunk 25+

well, its really hard to say because potential vs ease of growing is hard. Pineapple chunk says 25 but Ive grown it and doesnt come out as easy as say lemon haze which says like 22 in its possible best. Point being that the ones with highest potential arent always the ones that come out with the highest amount of thc. From my experience, lemon haze, xj13, blue dream, ogkush, they all come out with exceptional levels of thc. Bit also, sometimes the shit that is super crystally isnt ass high thc as something that is less crystally. First time i saw lab readouts that confirmed this it kind of blew my mind....

I look 3-4 days per week at the local menus around the bay area. I go to dispensaries several days a week. I vend to a club that lab tests everything. I'm looking. It's extremely rare.
As far as 27% thc bud. That is something I've never seen. I guess it's possible. I just always find it hard to believe when people make claims of bud being of a higher thc % than anything I've ever seen exist. Usually, it's bullshit.

HPLC, like what is used in CO by Full Spectrum Labs, tests about 20% higher than GC analysis, ie what is used by Steep Hill Lab. This is the cause of much confusion. Stating numbers, without the test method, is pretty meaningless.

Ahhh. I see. That makes a lot of sense. Seemed odd that that test company was getting results frequently testing 25% bud where I see that result around the bay area about once a year.
Highest I've ever seen is a batch of harborside Oakland's strawberry cough that tested at 25.25%. I rushed to Oakland to pick some up but it was already gone when I got there.
So that 27% bud would be ~20-23% if tested at steep hill. Still fantastic bud!

my LSD was tested in a lab here and it was 22%. highest ive had

Think about it like this. If something was 25% thc by volume or mass the entire bud would have to be almost all resin because THC only makes up a fraction of what resin consists of. When you see those higher numbers on hash like 80% - 90%, it's because it's separated in different grades through silk screens or bubble bags or it was made with solvents which would also get a more pure sample not to mention these tests need to be done multiple times to get accurate results. If you just do one run through on a 120 micron screen and get bulk hash the actual thc percentage on average would be much lower than those numbers you see in some of those extreme samples. It's impossible for thc to equal 25% of the weight of a bud, that would mean that you could get a huge return when you process your bud into hash. Ask anyone and I guarantee you they will tell you you're lucky to get a 10%-15% yield on hash.
Here's a link that will explain Chromatography and how all three types differ and how each method gives drastically different readings on cannabis even from different samples of the same sample : http://www.unodc.org/unodc/en/data-and-analysis/bulletin/bulletin_1994-01-01_2_page009.html
It will also explain that you are not getting readings of thc by weight/volume or weight/mass but rather it gives you the percentage in relation to other compounds depending on what you are looking for. You might not understand some of it if you don't have some type of science background but if you have questions just ask.

Not to mention there needs to be multiple tests run in order to get an accurate reading. I'm pretty sure it's just another way people found to profit off of the medical industry.

I got some stuff called HEROUJANA. Its a pheno type of OG Kush. Clones $2,000 : wow...
I have to say, the stuff was very strong. Near 30% Gets your eyelids fluttering.

Just wanderng the forum and have to say this guy is hillarious! "and from out of nowhere, a verbal haymaker from hell for no reason" LOL I'm cracking up-who lit the fuse on your tampon? LOL Thanks though-truely a great laugh this am.

And the fact is most labs will score within a small margin of error. There is a ring test put that looks at lab accuracy. Its really interesting to see how much shit talking there is on labs, when those talking do not have any facts related to the industry. If you tested on a GC your numbers will be lower than on an HPLC, about 15%. This is real science here, so I don't expect anyone to understand why that is. Fact is that the better labs have about a 1% margin of error on their apparatus, while the smaller labs run about 5% margin of error. Don't let the smaller jerks convince you that all testing is bunk, thats not a fair assessment. THC% is very accurate and useful for in lab comparisons, to see how my OG ranks compared to other OGs tested at the lab. Higher THC, relative to other samples of the same genetics, indicates greater plant health. Comparing lab to lab is garbage because the labs do not have any standard operating procedures, and most are using inferior equipment. But that doesn't mean that the larger labs are not accurate.

I'm pretty sure you are missing the point of lab testing. I will agree that testing for THC tells us nothing about the high or anything useful. But the labs are finding rare chemotypes and screening for safety. Thats what the labs are for. We would never know that jack the ripper has a high THCV pheno without the labs. A dozen high CBD strains that have been discovered, from lab testing.

So 25% leads us to "almost all", lol at your math. THC makes up about half of what is in trichome heads (hash) just for starters, so the "fraction" you mention is 1/2 to 9/10ths, a pretty large fraction. And 25% is high for flowers, but very real. You do realize that there is THC in the trichomes and the actual plant matter right?
80 to 90% numbers are only showing up on solvent extract. For the record, butane is an extremely good solvent for cannabinoids and achieving 80 to 90% is not hard when it comes to bho. Anyone doing a two solvent extraction (ie bho followed by an iso wash) can easily get above 80% THC, just putting that out there because its a fact.
LMAO brah, you are too much for me today. SOOOOO... as a hash maker I'll tell you that 20% yields on ice water and dry screen are possible, I got over 20% last week with my chernobyl using frigging ice water and trim. Solvent extractions commonly yield over 20%, very commonly, you should ask around. 10 to 15% is common for physical extracts, but as my research with Steep Hill Lab shows, the plant material still has lots of THC after extraction that could've been extracted with solvents. Physical extraction only gets 1/2 the THC on the trim. So a 10 to 15% yield of 50% THC means that there is another 10 to 15% THC still on that trim I compost. Go to page 46. When I extract flowers instead of trim the yields are way over 20%

The inaccuracy of crappy low-overhead labs do not make Steep Hill Lab's numbers less accurate. Again, you can't let the crappy inaccurate (low overhead) labs convince you that the professional labs are not accurate. The ring test shows how inaccurate the smaller labs are, but that doesn't make the established labs inaccurate. We need standardization in the cannabinoid testing industry, but that won't happen until its taken over by the govt.
Untested but 20%+ hash yields. Chernobyl

If you read the Laboratory Validation, in particular section 2.7 (Extraction Efficiency) and 2.8 (Selectivity and 2.9) (Specificity) the extraction of cannabinoids is referred to. That is what is then tested. THC percentages are in relation to all known cannabinoids.

Uh... what? Have you ever run a GC? The % numbers are from peaks, these peak numbers are in relation to everything in the sample that is detected, not just the 3 cannabinoids that have internal standards and are being reported. really...?
