I designed these seed propagation trays to be 3d printable. It’s a common style that I took off of a product I’ve seen on Hoocho’s youtube channel. You can find the link to his channel on the printables page.
I printed this in clear PLA as you need some light for the seeds. I unfortunately haven’t been able to give these a test run as I am going out of town soon but I didn’t want to wait to post them.
Nice! Have you thought about also adding a tray without a bottom, so you could stack them and allow young plants to grow a little taller before exposing them to the world?
