what i did was just mist the dixie cup container where the seed lives.
the other one of its batchmates is also slow growing,really slow but growing.but this one, really not. the taproot seemed to have 2 shades of white, 1/2 being white as it should be and the other half a bit yellowish.this was when i remember putting it into soil from the paper towel.i guess bad seed. this 2 were my favorite and last beans of its kind that i have.
