here are most issues with dispensary clones (not saying any of these things are true of any places above, i don't know them, just general knowledge):
*they are mostly 2nd/3rd choice clones. the primes are kept for the store grow.
*the dispensary staff isn't trained or has little knowledge on how to keep them happy.
*the dispensary environment isn't really setup for handling clones, but they do it anyways (humidity/temp issues).
*mold/mildew - some places have no clue in this dept.. it is seriously sad to see a room full of plants that aren't taken care of and show clear signs of PM or botritys. seen many clones that had it too. a good way to ruin a good grow.
*pests - same as above. spidermites, thrips, root aphids, scale. another great way to ruin a good garden. root aphids are the devils spawn. supermites are just as bad (thank god for the change in weather! wipe em out NOW while it's still early winter)
am I missing anything? oh yeah .. some just rename anything to whatever name sells good. same with the weed you are buying, I can almost guarantee that 5-10% of what is on the shelf has been renamed for marketing/selling better. some of the general public only cares about some name more then what the product actually does.
keep in mind though, that these are the minority. the majority of places want to retain your business and have you refer friends.
