"Gro-more" quadruple hydroponic minimalist net cup with solo cup feature
Description
How well do small root crops such as carrot and radish grow in high density hydroponics? Let's find out. As a bonus these are sized to fit atop red party cups for eventual use by students. I modified leonardlowe's rockwool holder (https://www.thingiverse.com/thing:4633665) after seeing photos of folks growing hydroponic chives, carrots, and radish VERY close together in seed germinating flats. Using these quad net cups you can grow four plants side by side, for abundant harvests of tiny root crops including parisian carrots, little finger carrots, and french breakfast radish. Overall dimensions are ~100mm diameter. Net cups all fit within an 85mm diameter circle- use a 3.3"/89mm hole saw for easy installation on tote lids. Round holes in the design are for a 6mm airline tubing and a 11mm large straw for a water level indicator such as joshc's self-watering planter indicator (https://www.thingiverse.com/thing:3792035).
