Forgot to add that the "days of no watering" after transplanting is a subjective estimation on my part based on my own knowledge and experience. As usual, it is difficult to find concrete answers from a credible source. But it should not matter much, 4 days to even 2-3 weeks, except for the delay in visible growth. The plant won't be in need of water to remain healthy because there is no water loss in the closed environment of a plastic bag; it just may not have enough water to grow substantially.
