  • Short height – Jack Herer reaches a final height of 80 – 120 cm – a fantastic indoor strain!
  • Max EC of water – 1.6 in veg, up to 2.0 in flower.
  • Recommended nutrients: CANNA COCO range.
  • Recommended grow method: 15 L pots with organic soil to bring out the best flavour and greatest yield Jack Herer has to offer.

An Invigorating Sativa-dominant Hybrid!

Jack Herer’s Sativa-leaning genetic lineage gives her a very balanced effect – a long-lasting, invigorating high that keeps you uplifted for hours on end. The ideal strain for daytime use, Jack Herer is very popular among medical and recreational users both due to her high cannabinoid content and well-refined terpene profile.
