I found this at another site.. fairly similar to what chimera said, however this uses easily obtained materials and gives an idea of %. which would give mass instead of roach size.. anhoo

"This method gets tweeked here and there over time....currently working on tweeking it to pre test male plants.

--------------

Pheno seedz' CBD test method

------------

1.5 ml micro centrifuge vial (snap top)
0.08 gram lye
Tiny roach sized "pinch" of plant material.
1ml of 50% iso rubbing alcohol (although 70% can be used)
1 tiny Carbon pellet (sold at pet stores in fish dept)

--------------

Do the following in this exact order.

Add 0.08 grams of lye to vial, add plant material, add carbon pellet (on top of plant material to get better visability of color change), add rubbing alcohol as close to top of vial as possible (about 1ml). Close vial securely and shake for 60 seconds (making sure lye is not stuck to bottom..give few light taps if lye is stuck), wait 10 minutes and shake another 60 seconds, after 10 more minutes the color reaction should be ready.

Green = 0%
Yellow = 0-3%
Orange = 3-5%
Maroon with slight purple = 5-8%
Light purple = 8-12%

--------------

LYE safety should be researched and understood before trying the testing.

DO NOT add over 0.08 gram lye as the more you add then the hotter the chemical reaction will be and you can get burned, 0.08 is the most sensitive amount for percent testing (under 0.08 and you may not get any color reaction)....I burned my finger when I tried 1.5 gram of lye.

You should try to use dense samples over fluffy samples (fluffy samples do not react as good).

You should perform the test 3 times to each plant...using the highest percent as final result. Taking a pinch from different buds or different areas of a bud.

Wash hands often and make sure to wash work area after, cover work area in paper towels or paper in order to better clean up after.

Purple Nitrile gloves are better suited than latex gloves when dealing with lye.

As extra pre caution you can wrap toilet paper or something around the vial during the shaking process.

Drain cleaners can not be used instead of actual lye (drain cleaners add dye to the lye).

from my breedbazy thread posted by cbdseeker"

So this in theory would show a "raw" idea/figure of CBD even if a Type/chemo 1 had some significant quantity of CBD in it's chemical composition?

cheers

Has this method been compared to known lab test results?

A link or mention of where to find the original thread would be helpful.

[clearheaded]

was cut and paste already, sorry. but it would appear it has been compared to test results. if want original will need to use the search engine on breeedbay.

Cant post the link but its easily googled. if look at bottom the post came with where to find it

[clearheaded]

the original must have compared test results otherwise just plucked from the air and not sure if even actually worked. however the reposter of this did not compare his results to it.

It also does appear to work on males test node material apprently as male flowers dont seem to work. get ChemoTYPE at very least and if works nearly as good as beam test thats a great thing as lye and rubbing alcohol is much easier to come across then pure ish ethanol and KOH.

Seriously cool and thank you for posting it. I'm definitely watching to see where this goes.

Questions...

Purpose of the activated charcoal?
Purpose of the proper placement of the charcoal?

Cool info. Going to try this, does fresh or dried plant material have an effect?

Hello Clearheaded,

That really interests me to include to use this trick but...
Could you to explain what is a "male test node material", please.
I do not have a well understanding of which part of the male plant you speak (sorry for my english...) to do that ?

Thank a lot for your time and this explanation.

Quite logically, the activated charcoal is sensible to be of use as filter of lye to lead the precipitate of color up by density in the solution.
