Is there any degradation or loss of vigor suffered by a plant produced from successive clonings of the same genetic material? That is, a clone having grown and then cloned, and that clone having grown and been cloned, and so on? Is there a limit on how genetically old a plant can get?

Ive dont it that way for a while w/ no problems. Ive seen a guy here on his 5th year and he hasnt had problems
