Sensi seeds has the original.
I'm thinking of trying some JH. If cost wasn't an issue which seedhouse would you use for your Jack Herer grow. Cheers
Sensi's Jack is not the same as it used to be so I don't think it's the original but rather a new selection maybe due to the loss of one of there parents.
Think............... It's not illegal yet
I grew some Jack Herer from Sensi seeds in the early nineties. The plants were out of control and the bag appeal wasn't that great, but the yield and the potency almost made it worth dealing with them.
I haven't grown it yet but when I do it will be Sannies Jack.
