We still have no roots, one thing I noticed is these all seem to be cut at the top and the bottom. Romulan is the only one with roots, and appears to be a one cut job not cut on top and bottom so maybe thats why it rooted easier?

I have Afgani Kush, pure kush/ sour deisel, granny, romulan, and sour d/chem dog, and they were $15 each
