Using seed pods to germinate seeds indoors is easy and a lot less messy than using seed-starting potting mix. Seed pods actually start out as pellets. These hard, round discs are made from Canadian sphagnum peat moss and wood pulp, compressed into disks. The disks, when soaked with water, expand into a peat pot. When the seed has germinated and the seedling is ready to plant in the garden, the entire peat pot goes into the ground.
Place your pellets face up (the side with the circle in the center) into a container. Any water-tight container will work; just make sure there is enough room between the pellets to allow for complete expansion of each. Muffin tins work well because they will hold the pod upright after expansion.
Add warm water to the each pellet. You don't need to add a lot of water. Add a few drops, allow the drops to soak in, and then add a few drops more, and repeat until the pellet has fully expanded. They will grow to seven times the height they were as pellets. When expansion is complete, pour any excess water from the container.
Insert your seeds into the hole in the top of the pod to the depth recommended on the seed package. As a general rule, if the seeds are large, push them down a quarter of an inch below the top of the pod. Smaller seeds can be planted nearer to the surface.
Place the container into the plastic bag and secure the bag with a twist tie.
Place the bagged container onto a heating mat set at the temperature suggested by the seed manufacturer, usually between 70 and 80 degrees Fahrenheit. Check the pods daily to make sure they they remain moist. Use a plant misting bottle to add moisture if they begin to dry out.
Remove the container from the bag as soon as the seeds sprout. When they are large enough to be planted in the garden, plant the entire pod.
