Hi everyone, I came across this device called MyDx in HIgh Times. I'm sort of a newbie here and I was wondering if this thing is worth it. It's cheap compared to me going and testing at a lab, and I can test the potency levels all throughout my grow and top and bottom of the plant. I've read some articles that talk about the plant having different THC levels at different parts of the plant. Anyway, I'd like some expert feedback, any veterans here that can lend their adivce? Is the $600 price tag worth it
