Dr chronic has LR, and almost always has it in stock, and is kick ass on the shipping times. 5 days from payment to my doorstep.
LR isnt as potent by itself. When it was crossed with ak i noticed an amazing difference, just an all around high. out of 5 seeds (not feminized) i got 4 to germinate, and 2 were males.
10-11 weeks in out bang done!!!! you cant beat it. If you look on his website there are diesal strains, ak, northern lights, and a few others.
