I am planning to test for CBD in the strains I have coming up. I was looking into the different avenues available to us. For me, sending out samples is out of the question. I'm too anal to wait for an answer. And, at $40 or more a test, it's not a great option. Setting up a small lab for High Pressure Liquid Chromatography (HPLC) or Gas Chromatography would be fun and certainly would be a learning experience but it definitely wouldn't be cheap. Thin Layer Chromatography (TLC) is probably the cheapest way to go but there seems to be quite a learning curve required to obtaining accuracy. While I was looking for supplies for TLC I realized there are a number of home testing products for sale. Some use TLC and others use chemical dye test methods. I have to wonder if there's any use in the drug test kits they sell for parents to test their kids for pot use. Here are a few of the home kits you can buy.... http://corp.cbscientific.com/product/combo-kit-test4-cbd-medical-marijuana-kit-thc-percentage-kit/ http://www.cannalyticssupply.com/ http://www.thctestkits.com/ Has anyone tried any of these? Any comments?
