Had several Jack seeds from an order a few years ago, but all germinated, and all grew to completion. Plants were about 2 ft tall, and each one yielded a couple of ounces. So – not the highest yield I’ve had, but pretty good. Almost all of the regular leaves yellowed and fell off by the end, but the buds just kept on growing, and everything turned out great. It has a really nice high – strong, but not so much that you can’t do whatever you need to. Very energizing and clear. Highly recommended.

Due of its odd earthy taste, I don’t think I could ever grow to like Jack Herer. Although it seems to be present in all marijuana, this particular strain is too potent for my taste. I enjoyed the results but disliked the flavor. Would advise you to give it a shot and judge for yourself because, on the whole, the strain is good.

Still my favorite strain. I took the head bud, ground it let it dry over night and smoked it the next day. No curing. When I smoked the first joint of this beautiful 6′ tall and 6′ round plant in my basement. I got so high I used the tv remote like an imaginary seat belt before changing the radio channel. I’ll be taken better care of this years and following the steps to see if I can grow it even bigger then the last Jack Herer auto crop king seeds I grew. Pictures and videos to come. I’ll have it involved with my cannabis art website. Also a help from crop king seeds, massive crop = massive joint art. http://www.tharonscannabisart.com

Has a significant impact on concentration skills and appears to keep the same zen-focused energy for about two hours. While smoking other potent sativas, a buzz can be felt as a warm sensation in the stomach as opposed to a full-body buzz.
