AJN has the most negative tests in this thread so far afaik-I've tested two of their strains myself. Please don't post your assumptions here as though they are fact. Green Acres is a reseller who buys his stuff at big clone sale events and direct from breeders. If you have a positive from a reseller, look to the origin of that clone for the culprit. I'd expect a lot of mites and PM from a reseller's clones, but HpLVd is unlikely because they rarely have the clones long enough to use tools on them. The highest levels of infection will come from the sellers who maintain a large stable of mothers and take their own cuts-I'm not going to name names, but you know who they are.
