I've certainly had some issues, my fault typically, not misjudging really but desperation, to save genetics, prevent plant kill off, etc. I just wont risk one extra plant, one extra gram etc, and in my perpetually harvested cycle i need patients to do what they said they'd do. when they dont, I fire them and replace them immediately.
I've got a star interviewing system that shows the knuckleheads usually before registration.
after registration patients never visit me, I meet them, home or whatever. All retired, disabled, no work woes, no unhappy people allowed here. I stick with the cool cats of yesteryear, my kind of people, back when you could believe that every mj users was cool.
used to think that....till I registered my first patients!!
