I always had problems with my Kratky bottles. Either, they were super hard to refill, or the plant just dropped into the vessel.
This adapter fixes that! You can just easily fill the nutrient solution into the funnel, and it will flow into the bottle!
Seed starting is also pretty easy. I recommend moss (preferably long fibred sphagnum moss) as "growing media" to fill the adapter, so the seeds don't fall in or dry up, and then you can cover it with saran wrap. The roots will find their way into the bottle once the seeds germinate.
I provide you one small (18 mm) for standard (wine) bottles, and one bigger (28 mm) I used for my laboratory bottle.
Prints in just a few minutes via vase mode and costs less than a few cents.
Preferably print it with transparent or lighter materials, since black filament will heat up a lot in the sun. PLA will break fast, so PETG is the best choice.
You can include a wick if you want, useful for the start.
