Peperomia Propagation

Above are my Peperomia Polybotrya (Raindrop) and Peperomia argyreia (Watermelon) growing in water for 6 weeks in a west facing window. Peperomias have been the easiest to propagate but are slow growing. 

Watermelon in water for 10 weeks. Lots of root growth and tiny leaves emerging.
