Sow cress and harvest easily
I always do that in compostable egg cartons. In the individual wells I give a soaked piece of the compostable material. That comes from the packs that sell tomatoes that are pretty smooth. But of course you can just take earth, cotton or kitchen paper.
Sow cress, keep well and harvest. The ten wells have practical portions that you can easily cut, and you can seed immediately. And if you have lost the desire or it does not work, the egg carton can completely migrate into the compost.
Have fun and good luck! :)
