If you’re looking for an easy propagation container, ask your grocery store Deli for a rotisserie chicken container. I like these because they are domed and give the plants room to grow a bit. You will also see in the one I got, it already had 2 vent slots in the top. I lifted up the tabs to allow air flow. I am propitiating a Fireworks Begonia that I cut up and stuck in the soil. Excited to see if this propagation will take.
