Sure shows a lot more purple than the Cannatonic I sampled. Definitely higher CBD. On a side note, I have zero information on where the seeds for the sample came from, nor much info about the grow.

Thanks for sharing!

I run the HP (heul Perkins cut). His pheno tested highest out of what He or the previous growers pheno hunted and tested.

Love it. That purple is sure pretty, Yes? lol

Seems useful, thanks for posting.

However, I very much doubt you can get accurate readings of plants in veg. I would think flowers contain far more CBD than immature leaves.

No time to chat. Too much fun running tests. LMAO

Here is a Cinderella99 with no CBD and a 4 weeks into flower MedTree Continuum high CBD.

Back later with more.

This was my initial thought as well.
If anyone can explain why it CAN, im all ears. Im having a hard time wrapping my brain around this part.

Vegetative material from very low CBD strains has produced zero purple. Vegetative material from high CBD plants has produced light purple. You tell me? I only have one very high cbd strain and a couple non-cbd plants to test. Only the high cbd is in flower.

Anyone growing out some "cbd-rich" plants should be able to see color variations, even from vegging plants. The key is consistency in taking samples, drying, crushing, weighing and shaking times.

The Med Tree Continuum I'm growing is a high CBD, low THC. I think 1:50 or something like that. I'll run some sugar leaves, some fan leaves and some small stems tomorrow.

I'm only about 4 weeks into flower so I'll have to pick some and dry it. I'm not a big fan of oven drying. The tests I ran today were on 1/2 dry that I clipped a few days ago.

I think I remember 15 minutes at 150F to oven dry the samples in the orig 1942 patent. Maybe I'll try that.

A dehydrator you can run without heat works well. I have a huge one, which is a bit of overkill for drying small samples. I urge anyone who can, to run this test on their vegging high CBD plants, especially if you have multiple phenos. Please! I know there are a lot of us who would love to have you share the results.

Glad you're having fun Ringodoggie. It's pretty cool running a simple test like this. Reminds me of high school chemistry class. lol

I have 5 week old clones in veg. 3 phenos from the mothers I am testing now. So, we can compare the potency of a flowering leaf vs vegging leaf from the same strain and pheno.

I am just getting started. I can't get into my flowering room for an hour or so to trim so I am going to run some tests on the remainder of what I have.

First task is to compare carbon pellets, granules and powder. I tried some powder yesterday and it was not great. The carbon never really settled 100% so it made the results darker than with granules. I am going to try pellets in a minute.

Also, does the shake really have to be 2 minutes? After about 30 tests, my arm got tired. LMAO I tried some 15 second shakes and it seemed to make no difference.

Also, just a quick run-through so I understand.....

The lye heats the alcohol and in essence, extracts the cannabanoids from the pot and (in some small manner) decarb's it. (otherwise, we are measuring CBDa, right?

The carbon is a filter that absorbs (something) and the remaining substance when mixed with CBD is purple.

Yeah, just like high school chemistry. Unfortunately, when I got to college, biology and chemistry made way for sex, drugs and rock and roll. Wish I had stayed in school and took more chem classes. LMAO

I am pretty free today and plan to stay inside and play with my toys most of the day. Raining and shitty outside. If you have any special request, please feel free to ask. I'll do what I can.

Couple things I can add for people trying this....

Gloves and glasses are a must.

A funnel that fits into the vial is awesome. Check out 'gold prospecting' stuff on ebay. That, and the cocaine funnels work well.

A tiny spoon to scoop the carbon and lye. I use a 1/8 tsp from my kitchen. I took some small jars and put some of each (carbon, lye, 50/50 alcohol and 91% alcohol) into the jars and set them on my lab bench right in front of me. This makes it easy to reach everything without stumbling over assorted bags and packages.

When cleaning the vials for re-use, a Q-tip gets inside real nice to swab it. After I rinse mine, I swab it with alcohol and rinse again. Q-tips.

I'll post whatever tips I learn along the way. Let me know if you need anything special.
