Okay I talked with my hydro guy. He has been growing forever. According to "John" you can clone hundreds of times without loosing any quality. Considering this guy has been doing this for over 40 years I pretty much accept what he says as gospel. The exact amount of times you can clone without loosing quality can vary from strain to strain. Your most clonable (is that even a word?) strains seem to be those that you can't start from seed. That you can only get from clone only. Is there something built into their genetics? Maybe.
