The growing time for red potatoes can be from 70 to 120 days, depending on the variety you choose to plant and what size you like your potatoes.
I'm not sure that I understand your question, but sweet potatoes will begin to develop around 30 to 45 days after planting; after about 95 days, they might be ready to harvest, but they can be left longer as long as there is no danger of frost.
