its true that 90% of the clones out there are crap. but if you do your homework, talk to the guy on the phone to feel him out and carefully inspect the clone for root rot, mites, aphids and mildew you can actually find decent strains. Just a tip, it's absolutely necessary to talk to them on the phone first to see if they are a kid or not. no offense to you youngsters but my experience is people in their early 20s and younger tend to scam a lot more than older folks.
test them out by asking if they have 12 of each strains, lie about being able to carry more plants. the idea is if they say yes, they have 50 clones of whatever you ask, they are most likely just mislabeling clones and giving you whatever is available. the legitimate people will tell you 99% of the time that they don't have that many clones and to ask a week later when more of a particular strain is available. the key is finding someone who says the latter, it's worth the wait b/c you know you will be getting the strain you asked for since they are not available immediately.
hope this helps if you decide to go ahead and buy clones from cl
