Should I give up on this seed?

Hey gang. It's been 4 days and this is all the further this seed has sprouted out of the ground. I'm either growing the smallest plant EVER, or I think I've got a dud here. Thoughts? I planted it when I had about .5cm of taproot out of the paper towel.

LEAVE IT ITS GREEN

May aswell try, just use water, maybe root stimulant to assist root growth

with my second batch I only got two to sprout (10 year old seeds) maybe more! But I let them grow under paper towel and two plates under my mattress (slept on the couch) let the get about 2 inches of tap-root, then added an extremely diluted mix of micro, and grow (flora) tested ph of the water (6.5) perfect, added that to the towel, it sprouted some secondary roots, then I planted into a small clay pot, just seedling dirt. They are doing well now!

It may just suddenly take off for you...a little more patience maybe? Not TELLING you anything, just suggesting.
Good luck.

Be patient it might surprise ypu

Alrighty. I'll leave it be for another 3 days or so. I'm headed out of town so I'll check back Saturday morning.

If it still looks like this Sat morn, I'm going to call it and pop a clone in its place. Thanks for the advise, gang.
