Hi all. I’m in real need of an accurate thc/cbd potency testing machine. Have done some research and found that there are more bad than good according to reviews. Tried cannalytic supply and it’s too hard to get a good reading. Wondering if anyone has used tcheck 2, mycannadx, purpl pro, hygrade or any other machine. Would I be able to use a spectrometer instead?. If so which one would I use?
