Decline in potency

When cloning, how long can you keep taking cuttings before potency declines? Can you take cuttings generation after generation indefinitely, or will this eventually weaken the potency?

There is no decline in potency from a clone line. The clone is an exact genetic reproduction of the plant from which it was taken. Only an infection or disease such as a virus will create a decline in potency.
