Per the Wish spell:
You don't need to meet any requirements in that spell, including costly components. The spell simply takes effect.
Per the Clone spell:
This clone forms inside as a sealed vessel and grows to full size and maturity after 120 days.
Does the Wish spell eliminate the need for the Clone to grow for 120 days? Or when it says "the spell takes effect" is that "effect" to get a wizard embryo?
This is somewhat related to this question about wish eliminating the material requirements for the clone spell.
