Just a followup on this, I've now finished, dried, and sampled all three. They are all very potent so no comlpains there, but there are some differeces. My favorite is Jack Herer for its overall balance of potency, yeild, and finish time. My biggest dissapointment was Vanilluna - the yeild was awful, really pitiful after seven weeks of veg. The flowers were beautiful and purple and the smell and smoke is top shelf, but not as good as DJ's Blueberry. The NL5xHaze is similar to Jack, gets very big, and the smoke is definately haze in character. I like it a lot but it took 11 weeks to finish. None of thses strains yeilded extremely well but they are all worthy to grow an make excellent "private stash" additions.
