Hydroponics miracle grow pod for growing plants in a hydroponic system. Works great with any system that uses miracle grow pods. Just put some grow medium, (I use paper towels, but rock wool would probably be ideal) into the pod with a few seeds and put it in the system. Also can be used to make your own system with a simple air pump, air stone, some tubing, and an opaque water container. Plant can either continue to be grown in the hydroponic system, or transplanted once the roots are thick into soil.

I printed this in PLA at about 50, with 0.8mm wall thickness, and 15% infill.
