Red cup kratky lid

thingiverse

Update 2020/06/23 Adding a rockwool_pebbles_pod.stl file that's virtually identical to the previous rockwool_pod.stl but now comes with a feature to place clay pebbles at the top, keeping plants upright. This was discovered after some time. Use American party red cups for growing vegetables! I'm using Kirkland "the big red cup" ones. It's a typical Kratky setup where you fill 3/4 of the cup with nutrient water. The design consists of two parts: one holds a 30x30x30 rockwool cube, and the other is the actual lid. All prints are done without supports. The lid_standard_pot.stl design is intended for use with standard pots from this project: https://www.thingiverse.com/thing:3405964 This setup is very convenient as you can directly start seedlings in the red cups, let their roots grow, and when ready, place the pot inside your grow tower.
