Fastest sativa I have ever grown
Finished in just under 8 weeks! The buds are dense and covered in trichomes. Classic Jack Herer flavor with an extra kick. Will definitely order again.
Perfect for my short outdoor season
Living in the PNW, I need fast finishers. Jack Heir delivered exactly what was promised. Harvested mid-September with zero issues. Energetic, creative high.
Incredible genetics, beginner friendly
First grow ever and I pulled over 400g. The strain is super forgiving and the smoke is smooth with uplifting effects. 10/10.
Great strain, stretchy in flower
Excellent quality and fast finish. Only 4 stars because it stretched more than expected in early flower. Plan for extra headroom.
