I want to use as little rockwool as possible, so I designed this small version. No additional functions (yet), such as automatic watering.
Print the lid from clear PETG in vase mode with a forced outer line width of 0.8mm. Also works perfectly with a 0.4mm nozzle.
Print the other parts with at least 3 outer walls and 4-5 bottom layers to make it watertight.
The author marked this model as their own original creation.
