Ever wanted to grow your favorite strain? Leafly and General Hydroponics are teaming up on a series of grow guides that will equip you with all the tips and tricks you need to grow different strains successfully.
Strain Overview: A classic strain developed in the Netherlands, Jack Herer is a cross between Northern Lights #5 and Shiva Skunk. The name comes from the cannabis activist Jack Herer. This strain offers a clear, motivating, and creative high that has launched this strain to global fame. There are a number of phenotypes, most of which are sativa-dominant while less common is the indica phenotype.
Grow Techniques: Jack Herer is a great option for hydroponic systems, but it likes to grow bushy so make sure there is enough spacing between plants. If growing the sativa phenotype, be aware of stretching and make sure they do not outgrow your space. Also ensure that the branches are supported as the buds develop to prevent any from snapping.
Flowering Time: 8-9 weeks
Yield: Moderate (indica phenotype); low to moderate (sativa phenotype)
Grow Difficulty: Moderate to hard
Climate: Moderate climates with temperatures between 70 and 85 degrees Fahrenheit.
Indoor/Outdoor: Grows well in indoor hydroponic gardens where the feeding and climate can be controlled. If you have a known sativa phenotype and live in a climate with warm fall weather, let Jack Herer grow outside and see how truly massive a sativa can get.
Feeding: Sativa-dominant plants can be vulnerable to overfeeding. Make sure to feed lightly at first, looking out for nutrient blockage or burn. Flush plants if you ever feel like you have overfed. Silica-based foods will help the plant develop thicker stems to support the buds.
