This was a qualified success. Used to plant things that sprout quickly and go into the ground relatively soon after sprouting, these were great. But when I tried using them for seeds that take longer to germinate and grow to having second leaves, the cardboard from the rolls started to have problems – it got moldy and attracted fungus gnats and then started to fall apart.
Since the quick-sprouting, quick-maturing seeds tend to do relatively well in the ground anyway, I’m not sure this approach really has a lot of long-term merit.

Saw this on Pinterest and it seemed worth a try. Seed pods are not much good for deep rooted or larger plants. I have a few more nubs of ginger I want to sprout indoors as insurance in case the main stuff doesn’t sprout. I also will want to get some beans started and they are notoriously hard to transplant. These seem like the cheap alternative to peat pots.
Bonus: actually labeling the things I planted. I am bad about that
