It took longer than expected, but my #hydroponics video about Kratky bottles with 3d-printed parts is ready.
I tried other bottles but these 2l milk jugs are perfect in having wide throats, being stable against winds (I grow plants on an open balcony), and the size is good. They also pack well side-by-side since the bottom is rectangular.
The current batch of seedlings shown in the video is already bottled, mostly, with basil just about to. I'm currently out of empty bottles, and still need to sprout the seeds for the big container too.
All the models are made in FreeCAD, all the animations — in Friction2D. The milk jugs are local :)
The original inspiration by Hoocho's.
