Out of all of them, I would consider Dinafem's "Industrial Plant".......it has the same parent as the original Jack Herer and when finished properly, is absolutely wonderful. It will need a full 10 weeks, but will reward you in many ways. I've heard good things about Peak Seeds N.L. but they are out of stock for 2 more months. Sensi is the original, but it's a lot different than it used to be. Nirvana is hit or miss and out of theirs, Aurora Indica may be the way to go if u go with them (it's very smelly though)....hope this helps some.
