18 bucks/seed is a bit stiff and i haven't seen any decent jack herer in years. i've been around recent grows/harvests of it but wasn't impressed with either flavor or potency. if i were planning on growing sat's or sat dom's right now it'd be c99. it has everyhthing jh used to have but finishes much earlier and does much better indoors. if doing it outside, c99 will easily finish by early to mid oct while jh will be lucky to be in before nov 1st.
