I have a seedling with the first set of serrated edged leaves and about 1/2" long. In my limited experience I have not seen the way these leaves look before at this stage. The individual points are very well defined and raised throughout the leaf. If it were metal it could probably cut. They are very sharp and well defined. It is also a darker green than what I have normally seen. I dont have a pic at the moment but was wondering if the description was enough to get an idea about this seedling. I am planting from seeds and know nothing about the strain.
