Parts of my family are in the bedding plant / greenhouse business. One cool technology is the transplanting machine. This transfers seedlings from "plug trays" to "flats" and replaces an assembly line of ladies doing this work. Here is one design:

The ones they actually used were the "Harrison Transplanter".. could not find a video, but here is one http://bid.sheridanauctionservice.com/images/lot/3471/347193...

Harrison is neighbor of ours who worked at Brookhaven National Labs but then became an entrepreneur. He sold a bunch of them.
