Measuring THC levels

I am about to order 3 Cannatonic seeds from resin seeds. I see on their website that the levels of thc to cbd vary on the phenotype. Some ratios can be a 1:1 or can be higher cbd to thc. How can I tell or check? Since I do have 3 seeds I want the phenotype that has the highest cbd to thc ratio. I’m growing this strain primarily for the cbd content. Do I just have to wait for harvest to know which phenotype I ended up with?

not sure how accurate these are, the only other alternative i'm aware of is sending it in to a lab, like steep hill

think they charge around $ 50.00 us for a standard test

The amazon link is an at home drug test.

Follow this link and read through it pretty throughly. You can get a rough idea of the relative concentrations of THC and CBD using Thin Layer Chromatography. It’s relatively simple to do and @PhenoMenal was kind enough to go into thorough detail on how to do it.

You guys ever use a mydx?

One of my friends got one, he used it on a little nug i gave him, results were pretty cool seemed fairly accurate as well. He emailed me results, looked like a legit test from a lab. Lab's here only work with licensed dispensaries(fuckin lame i know) because of some retarded law that was passed a few years ago.

I've looked at that product a few times over the last few years. I'm waiting until they get to their promised "subsequent generation" for accuracy. At the price they want, being within 20% is steep imo. Thing is, they've had this statement on their site for at least a couple of years. I think their database could be helpful for determining cannabinoid/terpene profiles for specific ailments longer term. For now they'll stay in my bookmarks until either the price drops significantly or they increase accuracy.

From their site:
"MyDx is able to quantify THC to within 20% of conventional gas chromatography instruments. Our subsequent generation devices and sensors will target a marginal error rate within 5% of GC values"

Don't hold your breath, i think their company is almost belly up, their stock is worth less than 1 penny per share.
 
Lol, another reason I haven't pulled the trigger. They've always seemed a bit sketchy to me, something just don't smell right...
Their still going. I just did a bunch of research on them and other "tests" like the Tcheck. They got one coming called cannabiox, i think, but mydx is, and I hesitate to use the word scam, but its implying that it tests your flower. It is not, it uses an algorithm and pictures you take of your nugs and then finds images it is "most like" and then uses the information from that known entity to give you levels for thc cbd, etc. Even Tcheck looks like a scam. There's a video on YouTube were this lady is using a Tcheck device (v2) and it spits out a test result while the unit is empty, with no testing slide inserted. Unfortunately, The only answer for home testing is buy an insanely expensive piece of lab equipment and do it right, pay to have the test done by a professional lab, or use the test from compassionate analytics and ballpark your results.
 
I read the thread about home testing using the TLC method and it made me want to spend 15000 dollars on a gas chromatograph.
