Seedling pot made from an empty toilet paper roll. After germination, it can be buried directly in the garden bed as is; the roots will grow through the softened cardboard, and soil organisms will then consume it. Make sure to only use toilet paper rolls made from unchlorinated and unprinted cardboard.
edit: please check if recycling has a problem with chemicals or heavy metals in your country
This is my first time growing from seed and I haven’t transplanted yet, but my friend has been using them successfully 🤷🏻♂️ she’s the reason I’m doing it that way (and me having no money lol)
It may depend how sturdy your brand of cardboard packaged eggs are I guess
