microscope is definatley the way to go I got a 30x one wicked little thing it is I wanted to look at everything. If y cant get one go by the colour of the hairs when about 50% have changed colour (I think its 50% ish but Im sure someone will correct me if Im wrong) it should be just about ready. Y dont have t hang it t dry it its just easier that way. Hang it till the stem snaps when y try bend it depending on conditions takes about 2 weeks then into the jar to cure.
