THC-CBD: Home potency test kits
There is certainly some discussion on cannabis forums about home test kits, but I am surprised that there isn't more, given the amount of online discussion there is about other marijuanistic subjects. (I just made that up.) There seem to be two companies lead the charge in selling kits using Thin Layer Chromatography (TLC) technology: Cannalytic Supply and THC Test Kits, in the area of $150 for the same kind of kit. Alpha-Cat is European a little more expensive, but perhaps not on a per-test basis.
On examining the two sites, I conclude that Cannalytics Supply has a somewhat slicker, more professional site, and is well written. However, the THC Test Kits site has an instructional video and links to live hands-on training courses in various locations in North America.
I started this thread in the hope that people with experience with such equipment might comment about what they think to be the best approach and/or product.
If I have broken any rules about mentioning brand names, I'll expect to hear about it.
