Once in awhile I'm reading something stating the THC level is ___%. How do you figure that out? Did I fall asleep during THC level reading 101?

It's something you have to investigate at the molecular level. Unless you have a chemistry lab in your grow room you're out of luck. You can guess though and roughly say what it is based on some other weed which you already know the strength for. Not accurate though.

If I had a lab, what is the process? Would it be really expensive to test it? I'm just thinking that the Hemp Oil made with really high THC buds would be the best for cancer treatment.

Oil extraction is a near perfect way to determine the true THC percentage of your bud. If you weigh the product before extraction, then again after extraction, the difference can be expressed as a percentage.

I would think this figure would be slightly inflated due to some of the plants waxes and non-cannabinoid oils remaining in the oil solution.

Although if you had a lab, you would take your oil sample and test it with a Gas Chromatography-Mass Spectrometry device.
This will sort out all the other "non-THC" compounds.

Well that went over my head! I was hoping it was more like my pool samples. Dunk in the stick and compare the color it turns to the chart on the box. lol Pullo is there a way to figure out the percentage without going through the extraction first? Or is that the only way to figure it out?

I'm sorry, that is the only way to determine a percentage.
But a good rule of thumb to go by is, if it is a heavy, hashy, Indica strain should be best for oil yield. The stickier the better.

Here is a link to Canalyzer Cannalyzer - Applications


Applications For Medical Users
Test the strain yourself before you buy or ask your local cannabis provider to show you the menu according to analysis results. It is best to keep a journal of strains that you consume to treat your symptoms. As you find strains that work for you, you will see a correlation between the analysis and those particular strains.
For Pharmacist & Care-takers
Monitoring the percentage rate of change of the cannabinoids during storage, in terms of the amount of acids present and the presence of the degradation products (due to aging & oxidation) of THC (= CBN) and the forming of degradation products of CBD (= Canabielsoin) and CBC (= Cannabicyclol). Display the fingerprints and THC% of your varieties ‘’on the menu’’
Clear information for the customers, on the desk!

For Growers
CAT is used for harvesting, storage and quality control.

For Horticulturists & Breeders
Monitoring the percentage rate of change of the cannabinoids in the profile & change in THC percentage by changing one of the environmental parameters during the growth stage.
Determine the difference in the cannabinoid profiles of your F1-offspring and compare the profiles with the parents, P1en P2 and make your selection!. It helps selecting appropriate strains to meet ‘’your’’ needs
Variety recognition; The fingerprint reveals dominant, cannabinol expressing
genes in the offspring, from one or both of the parents P1 and P2.
The influences of maturity1, age, storage conditions and geographical origin on the cannabinoid profile of Cannabis species.
.
The biosynthesis of cannabinoids and other terpenes parallels the developmental stages of the calyx (five-part carpel structure of the staminate and pistillate flower.) and associated resin-producing glandular trichomes.
Determination of maturational stage and timing of the harvest is based on the average calyx and
resin condition (fingerprint) CAT is used to compare cannabinoid readouts to select parents for your breeding programme. If you were interested in breeding two strains, you would take fresh cannabis flowers from each strain and analyze them for cannabinoids. You can breed two strains that are complimentary or dissimilar ( for example both P1 are high in CBG ( = ‘’hashish’’ like variety, and rare in the marihuana community), or one is high in CBG, or one is high in CBG and the other is high in CBN. Once you have bred the two, you can analyze the flowers of the offspring to see the results of your breeding programme, and observe hybrid vigour you’ve created, as well as her successive generations (FI, F2, F3).

I can't actually find a way to get this thing I've looked around bunch of broken links to nowhere and some really bad write ups as to whether it is even accurate?

I don't know if it does what it says it does but here is the link.

This is another test kit similar to the other Alphanova

This looks like it is more up to date anyway.

In my area my compassion club was going to have certain strains tested at a local lab. After a bit of debate they scrubed it do to cost vs result. They concluded with many growers each having unique conditions etc they would not be able to consistently test at a reasonable cost. So they use the seed breeders as a guideline only.

There is much about these kits all over the internet and many don't say much good about them. So take it with a grain of salt.

I haven't been able to find a price for either one of those kits. I'd like to try one just to test a few things. Thanks for all the info.

Hi LOTF I am still looking around for a price myself. I'm getting mixed reviews all over the place about them. I will contact my centre tomorrow and ask if anyone there has any info. If I get the answer I will put it up. Now I'm on a mission. LOL

wouldnt 100% be all the pores filled with THC? You just have to start counting your buds pores after flowering stage, and then count the trichomes :p

Or take photos (after/before) and then count them later :D

You know there is more information about testing the levels of THC in urine then anything else on the web. LOL There is just not much in testing it before usage commercially available.

Lucky, let me know what you find out. Can't believe they show you a picture of the kit but no price.

Hey Everybody,I'am late as always.Here's a test kit that I think jangel found it along time back.It's called Cannalytics-fingerprint & test kit. http:Herbal Incense - Legal Highs - Digital Scales - Cannabis Seeds - Vaporisers - Paradox.co.uk Head Shop and it runs $161.16.I think it's the same one lucky posted the link the pisce is wrote on the fingerprint test.Pullo yes if you want to know the Gas chromatography-spectrometry test will tell it all and how much too.Labcor a testing lab that dose urin test for pre-empolyment can do those tests,but that gas chro,spect test cost $385.00 a pop at labcor's cost.They just look at the betacarotene levels and the temps at time it was taken.If it passes that your in if not they GCS test it.Any high up job dealing with nukes,highly toucky stuff they test those poeple urin with GCP test.Enough of that.The finger print test kit works if you do everything right.At lease it will put it in a ball park for sure. Peace

Thanks Toke. Now I understand why I couldn't find it. They renamed the blasted thing. LOL Maybe they made it better too. Most of the write ups about Cannalyse were somewhat negative.

The Cannalytics - Cannabis Fingerprint kit (previously called Cannalyse) is a unique mini-laboratory for home use. The fingerprint kit also contains a unique standardized & high performance developing protocol for thin layer chromatography, specific for cannabinoids and a total-extraction specific for Cannabis. The cannabinoids will be separated and identified on special impregnated TLC-plates.

Only a minimal amount of sample (100 mg) is needed for total cannabinoid extraction.
The Cannalytics Kit contains enough for 12 individual tests.

Cannalytics - Fingerprint & Test Kit - Assessories - Paradox.co.uk Head Shop

LOTF if you purchase one to try please post your results for us to see and give an opinion of it's overall performance.

Good luck.
