I disagree. I've had seeds that came out with just a stem and a seed on top. It took a few days for the seed to pop off and leafs to come out of it, but now that plant is bigger than the ones that had a better looking start.If its still a stem with a seed on top with no leaves after 2 days its fucked. Could be a number of reasons why it happened, did u place seed in with tap root up, did u wait too long after seed cracked to plant it causing it to run out of energy or it could be just the shitty genetics or age.
