Reusable Seed Starter

thingiverse

This is a reusable seed starter cup. Most seed cups use rock wool or pete moss cubes as a seeding medium to hold water around an incubating seed. This design endeavors to make use of water surface tension to allow water to wick up into and around a seed placed into the matrix. The matrix allows enough space for roots to propagate, and is reusable many times in that a plant will simply decay and wash out of it when completed, allowing another undamaged section to be populated. Best printed with TPU, so that the matrix can flex. Scale as needed, scaling to at least 150% is advisable, unless your printer can print 0.1mm well.
