Khay ươm hạt cho grow cup của Hydroponic Tower

A simple rack that holds hydroponic tower grow cups upright while establishing roots in a seed starting.   Blacks out the water area underneath of the tray to discourage algae growth.

Once the seedlings are established and there are roots dangling into the liquid through the grow cup, it is then ready to transfer to the hydroponic tower.

The fit is a little snug (for the Jiffy7 cups) but that's mostly the seam flash which wears down.  When slicing, you may want to use X/Y size compensation with +.4 to adjust the looseness, or just size to 100.05 %
