Reading Early Leaf Shape

Beitrag von justicebzwieg »

Leaf shape gives away sativa dominance well before flowering starts. Narrow fingers with widely spaced serrations and a lighter green colour usually show up by the third or fourth node, and in a mixed pack this is often the first sign of which seedlings lean which way. There is a side by side photo set on https://hazesativaseeds.com that documents leaf development across several seedlings from one pack, which helped me sort mine at two weeks old. It is not foolproof, but it beats waiting until the stretch to find out.
