Another one of my personal pilea peperomioides here in Australia. Notice a trend with my plants? Not my husband's hairy arms in the photos!! Yes, I use a lot of terracotta pots. Pilea peperomioides love these pots because the pots breath. They let the moisture dry out faster than most other pots, and help prevent root rot. More air can get at the roots too. Roots need air!
In the summer this may lead to you having to water more frequently but in the winter it can be a plant lifesaver!
Watch the over-watering!
