I understand my problem is lack of light, or a light source too far away, but here's my question about tall skinny seedlings...if you plant them deeper, into a bigger pot, will the stems, that are under the dirt, grow roots along that stem, like a tomato plant does? Or will the stem just rot and the plant eventually die. I have some seedlings that are so tall and thin, but (knock on wood) are not top heavy AS OF YET, and I don't know what to do with them. I do use a fan on them, to try to strengthen their stems. Also, when starting with seeds, what can I do to keep the plants from getting tall and thin before they can get thicker stems? Keep them in the dark for awhile? I have other plants, that I am growing in a empty fish tank, and have gotten them to a nice healthy state, but I can't fit anymore plants in there. These seedlings I speak of, they are seeds I got from a nice salesman and am curious to plant and grow them this summer to see how they turn out. But since they are outside the fish tank, they don't have that great light source and are tall and skinny.
