So the thinking is to plant it with a short tail so it’s not curling sideways on a plate?Roots have special cells that have little granules that float around in them (like a snow cone), which tell the root which way is down. So when you leave a sprouted seed on a plate the root can’t go down and starts searching for a downward path by growing back and forth. This is a waste of time as you want your roots going deep, not growing side to side. It’s not really a big deal if the root is up or down (since it will quickly reorient). More important that it can go down and isn’t left on a flat plate for days searching around for the downward path.
