I think that's against TOS, but anyone who is selling PO clones as their own and saying they are disease and pest free is either misinformed or is purposely misinforming you. At PO, I am told there is a sign on the door saying something to the effect of "these cuts have PM, deal with it" - but there are other members who will chime in I'm sure.
that sign was indeed there a couple months ago when i was in for the first and last time.
their website is one of the first to show up when you google broad mites. they've got lots of experience with em, unfortunately.
