no they will still grow but placing it down waste energy and time as root has to go up then back down root up it comes out and goes down
and i have dug them up and seen this in healthy seeds
may not make or break but why not do the most to insure your seeds and plants are their most successful

Size and timing matters.

If the root tip is small and just emerging, (hasn't begun to curve downward) it probably makes sense to place it root tip oriented upwards as you've mentioned.

If the emerging root tip is longer and already orienting downward, I place root tip down or at least angled in that direction. Seems to work fine.

I usually use the scuffed seed, paper towel method, although sometimes I simply place directly in soil, if I have a batch of seeds I'm checking for germination.

Most seeds behave uniformly, but there's always a few renegades...

lovely post. Thanks for your good work
