the thing is supposed to tell me thc not cbv. if i dilute it should tell me thc not cbv? what do i dilute with and how?If you get a 15 you need to dilute the sample. Then do the math.
what is the other test device?The TCheck only gives a total cannabinoid not just THC. There is another test device that actually measures thc, cbd...
If i had it to do over id get a different unit.
If you used coconut oil for instance then make a mix of 1-1 and re test. Then double the result
