    From Professional Seeds comes a wonderful double Jack Herer hybrid cross aptly named Double Jack. The goal of this cross was to breed for a shorter flowering time while still retaining the extremely high quality that the man himself, Jack Herer, worked so valiantly to achieve. Double Jack can get pretty large, is suitable for either indoor or outdoor cultivation, and finishes within 8 – 10 weeks. The flowers have a strong incense flavor with sweet accents and very powerful brain effects.
