if it popped try planting it. i just got done germinating 6 seeds and 4 of em popped like the second day and grew tap roots and two of em just looked like they popped just a little. well i planted the ones that just only popped a little with no tap root and now im getting all of them to come up through the soil. those ones that only cracked a little are just taking a little more time than the others. how cold/hot is the environment for the germ? might be too cold. i dont know if i read it right but colder temps will hinder its growth. someone please correct me if im wrong!
