No no, I think you may be ON to something. Because I think the opening of the first set of...ummm forget the specific names... leaf flaps almost ... will be at a angle to hang on ... pure speculation .... could you get a piece of paper, square, cut a slit on a radious, half way through your square, gently slide that slit along the flatness of your cloner where it meets under the helmet, just to give the tap root a support like a rim on a hat, till it grows a bit to support itself, then remove the paper easily by pulling out through the slit. HAHAHAHAHA gosh, I don't know if I even make sense.
This is why I love visiting growers threads, I think this is truly innovative. This should be called "DB Seeding Technique," yah man, I totally thing you've stumbled into a new method of your madness.
